THE HISTORY OF CONCRETEFrom the Phoenicians to the Present Day

“The basic recipe for concrete is sim-ple and all its ingredients occur natu-rally. Concrete is made from lime-stone, clay, mineral aggregates(sand, gravel) and last, but not least,water. When mixed a cement pasteis formed that binds the mineral ag-gregates which is the prerequisite forcreating a hard stone.” [GermanCement and Concrete Industry.]

This knowledge about “concrete”, abinder made of lime, brick dust orpozzolana, goes back to ancienttimes.

The Phoenicians mixed lime mortarwith volcanic rock 3,000 years ago.They produced a material that couldharden under water.

Via the Greeks this knowledge, alongwith the techniques, reached Italyaround the 3rd century BC during thetime of the Roman Empire. The pro-duction of compression resistantbuilding elements made of water re-sistant mortar, and pieces of stonethat hardened in formwork, made itsbreakthrough in the 1st century ADand became the standard for late

Roman architecture. Thus theRoman “concrete”, also called“Opus caementitium” after Vitruvius,was born. Throughout Europe, fan-tastic and monumental buildingswere constructed that are still ad-mired nearly 2,000 years later: tem-ples, theatres, cisterns, aqueducts,sewer systems, thermal baths,roads, harbour facilities, tunnels,bridges and houses.

One of the last great concrete struc-tures in the Roman tradition is the“leaning tower of Pisa”, the con-struction of which started in 1173. Amonolithic concrete cylinder withwalls 2.7 metres thick surrounds aspiral staircase and is faced on bothsides with hard marble. Concreteconstruction technology was con-signed to oblivion during the MiddleAges and only rediscovered around1700. Since then, concrete has beencontinuously developed and im-proved and is now the building mate-rial of today.

The Pantheon (2nd century AD) dome is made ofRoman light-weight concrete. The record spanof 43 m was only surpassed in the year 1913(Centennial Hall in Breslau).

NOTHING LASTS FOREVEREven Concrete Needs Protection and Must Be Repaired

Despite high quality constructionand resistance, damage can occureven to concrete. Repairs and addi-tional protection are therefore neces-sary. Different internal and externalinfluences can have a long-term ef-fect on the resistance of concrete.Through the typical use of concretebonded with steel, so-called rein-forced concrete, one of the most im-portant damage mechanisms is cor-rosion of the steel reinforcement.This usually occurs because the con-crete carbonates in the area thatcovers the steel or chloride ions (e.g.from de-icing salt) can penetrate theconcrete. Further damage ariseswhen moisture continuously entersthrough cracks which in turn pro-motes rust on steel and also causesfrost damage.

Due to the numerous causes of andtypes of damage to reinforced con-crete structures there have been dif-

While the repair guideline “Protectionand Repair of Concrete BuildingElements” issued by the GermanCommittee for Reinforced Concreteonly recognised four repair princi-ples, there are eleven repair princi-ples in the European standard.

ferent principles for repairs for manyyears. In Germany, these are de-scribed in the guideline “Protectionand Repair of Concrete BuildingElements” (Repair Guideline) issuedby the German Committee forReinforced Concrete (DAfStb). Aftera phase of coexistence, theEuropean standard series EN 1504(in Germany DIN EN 1504) “Productsand Systems for the Protection andRepair of Concrete Structures” cameinto effect in 2009.

With the introduction of EN 1504,specifiers are given a considerablygreater degree of freedom. Thespecifier selects a repair principle forthe respective measure takingboundary conditions into accountand then selects a correspondingprocedure from part 9 of the stan-dard. All product related parts of thestandard refer to these principlesand procedures. Kaiser Wilhelm Memorial Church – Berlin

DAMAGE MECHANISMS IN CONCRETE STRUCTURESCorrosion of Concrete and Steel

From a thermodynamic standpoint,cement stone is not a stable system.This fact was not known or mostly ig-nored for a long time. In the past,more attention was paid to function-ing capacity and production coststhan to durability when producingconcrete structures. The damagethat occurred as a result was usuallyonly visible years later.

Damage to reinforced concretestructures can be subdivided into:damage of the concrete itself (con-crete corrosion); and damage that re-sults from corrosion of the steel rein-forcement (steel corrosion).

Damage to concrete is essentiallydue to the following causes:

� Unsuitable original materials during production

� Individual components are notcompatible with each other

� Environmental influences� Influences from utilisation� Construction errors� Design errors

Depending on the ambient conditionsto which the concrete is exposed,there are different types of concretecorrosion (according to DIN EN 206-1/DIN 1045-2) caused by:� Frost attack with and without

de-icing salts � Chemical attack � Wearing

From this list it becomes obviousthat you must also distinguish be-tween environmental influences andproduction errors as the causes ofdamage to reinforced concrete.

Environmental influences can be ex-haust gasses, acid rain, frost and de-icing salt, but also simply carbondioxide from the air. These eithercause damage directly or change thechemical properties of the concreteso that the steel reinforcement in theconcrete starts to rust. Since rustedsteel is larger in volume than non-corroded steel, compression stressresults, causing the covering con-

crete to crack and burst. If the rein-forcement is too close to the surface,such damage can occur at a veryearly stage if the concrete is not pro-tected.

7

In young concrete, the steel is pro-tected from corrosion through thehigh alkalinity of the pore water (pH ≥12.5). In this pH range, a microscop-ically thin layer of oxide forms on thesurface of the steel which sup-presses disintegration.

If the pH value of the concrete fallsbelow 10 through carbonation (be-cause it has absorbed CO2), or thechloride content exceeds a criticallimit value, this “natural” corrosionprotection is lost in local areas orover larger areas. Once this state hasbeen reached and moisture (as anelectrolyte) and oxygen (which isnearly always present) are present atthe same time, corrosion results.

Since corrosion products are largerin volume than the starting materials,the concrete that covers the steeloften bursts.

Prerequisites for the corrosionprocess in steel reinforcement are:� Electrical conductivity in the metal

(always present)� Anodic disintegration of the steel

must be possible (the pH valuefalls below 10)

� Electrolytic conductivity aroundthe metal (water)

� Differences in stress and potential(practically always present)

� Oxygen in the electrolyte (alwayspresent except in underwaterareas)

NEW RULES AND THEIR IMPLEMENTATION Which Standards and Rules Will Apply in the Future?

To successfully repair concrete, theexact cause of the damage must beknown. This will allow the correctmethod of repair to be undertaken. Arepair will only be successful if thestructure is restored, as close as ispossible, to its original state. The statea reinforced concrete structure shouldhave is determined, among otherthings, on the basis of exposureclasses according to DIN 1045. Bycomparing the stipulated state astructure should be in with its stateupon review, the need for repair be-comes evident. While drafting a repairconcept, different repair options canbe derived from the state and expo-sure found. After taking both eco-nomic and practical aspects into con-sideration, the most favourable repairmeasure is then selected.

Until now, the guideline issued by theGerman Committee for ReinforcedConcrete, “Protection and Repair ofConcrete Elements” (RepairGuideline), governed the specification,execution and supervision of protec-tion and repair measures for buildingsand building elements made of con-crete and reinforced concrete accord-ing to DIN 1045. It consists of fourparts:

Part 1: General rules and planning principles

Part 2: Building products and applications

Part 3: Requirements on contracting firms and supervision of exe-cution

Part 4: Test methods

Since January 1, 2009 the Europeanrepair standard series EN 1504 has

been in force. Existing national stan-dards and guidelines either no longerapply, or apply only as supplementalor additional rules.

EN 1504 is divided into 10 parts. Part9 plays a key role since this part ex-plains the “General Principles for theUse of Products and Systems” towhich all other parts of the standardrefer, particularly parts 2 to 7 which arerelated to products.

9

EN 1504-9 Total Freedom for the Designer

Part 9 of the standard follows theprinciple “Total Freedom for theDesigner“ and therefore does notprovide any binding rules or“recipes” for the individual case.Instead it contains principles andmethods that are understood asprinciple possibilities for solving aproblem and should prompt the“knowledgable designer” to thinkabout the consequences of each de-cision he makes, from diagnosingthe damage, through planning anddrafting a concept all the way to adetailed tender and selecting theright materials and systems for theindividual case.

The steps required to achieve suc-cessful concrete repairs or protectivemeasures are: � Assessment of the actual state� Determination of the causes of

damage� Specifying the goal of the protec-

tion and repair measure� Selection of suitable protection

and repair principles� Selection of repair methods� Specification of product and sys-

tem properties� Specifying maintenance require-

ments after repair has been car-ried out

The importance of this approach wasnot stated with such clarity in anyGerman rule.

In Germany, the state of harmonisa-tion of the product related parts ofEN 1504 is not uniform. Since 2009repairs must not only comply withthe European standard but also fulfilnational rules - particularly when itcomes to repairs relating to struc-tural stability. Conformity with EN1504 is shown by the CE-mark, whileconformity with the remainingGerman rules is identified by theÜ-mark.

Principles 7 to 11 deal with the cor-rosion of reinforcement which can becaused by:

� Physical loss of the protectiveconcrete cover

� Chemical loss of alkalinity in theprotective concrete cover result-ing from reaction with carbondioxide from the air (carbonation)

� Contamination of the protectiveconcrete cover with corrosion pro-moting substances (usually chlo-

ride ions) that entered the con-crete while it was being mixed orfrom the environment

� Stray electric currents from neigh-bouring electrical installations thatwere conducted through the rein-forcement

If the reinforcement is already cor-roded or there is a risk that corrosionwill form in the future, one or more ofthe following corrosion protectionand repair principles must be consid-ered before selecting a repairmethod.

In addition, the cross-section of theconcrete should be repaired accord-ing to principles 1 to 6, if necessary.

FAIR-FACED CONCRETE PROTECTION WITH HYDROPHOBIZINGAGENTS The Most Simple Surface Protection for Concrete

Treating building materials with hy-drophobizing agents is a methodthat has been used for many cen-turies to protect buildings. Vitruviusdescribed the use of natural oils tomake mortar water repellant andthus more resistant in his famouswork “De Architectura Libri Decem”.Today, silanes and siloxanes, in par-ticular, are used to hydrophobizemodern building materials.

The effectiveness and durability ofhydrophobization is determined bypenetration depth and active ingredi-ent content in the area of the buildingmaterial close to the surface. That iswhy Funcosil impregnation agentshave high effective ingredient con-tents and are formulated to achievedeep penetration. Treatment with ahydrophobizing agent is therefore asimple but high quality measure to

protect both new and old concretestructures from corrosion damage.

Particularly in cases where the con-crete has a more dense structure,this innovative cream technology isused. Funcosil IC is an all-roundproduct for these cases.

Remmers Funcosil C 40 was specifi-cally developed for concrete sur-faces that are already strongly car-bonated. It is a cream product withspecial catalysts that ensure that theeffective ingredients react quickly,even if the alkalinity of the substrateis low.

Remmers Funcosil BI, a liquid im-pregnation agent with an active in-gredient content of 80 %, is suitablefor use in many situations, especiallyfor less dense concrete surfaces.

Properties and Advantagesof Remmers Funcosil IC:� Cream technology – out of the

bucket right on the wall� Easy to work overhead� Excellent penetration depth through

long contact time on the surface� An active ingredient content of 80%

ensures a high active ingredientconcentration at the edges of theconcrete

� Visible, uniform application pro-vides quality assurance

� Less material is needed – it is ap-plied just once

� Solvent-free� Best possible “performance”

17

Coatings are used to produce aclosed, protective layer on the sur-face of concrete. This protectivelayer can take on different functions.

� Protecting concrete againstingress of damaging substancessuch as salts and CO2

� Regulating moisture balance andincreasing electrical resistance

� Increasing physical resistance� Rigid or flexible crack-bridging� Excellent base for “decoration”

Remmers concrete protection coat-ings, “Concrete Acrylic” and“Elastoflex Facade Paint” have the fol-lowing properties:

� High water repellency � Excellent hiding power� CO2 inhibiting effect which

prevents carbonation � Water vapour permeability � Limitless possibilities for

decoration

The floors and the floor slabs of bothaboveground and underground park-ing garages are subject to high me-chanical loads from vehicle trafficand the accompanying emissionswhich bring in chlorides. These twofactors put the floors at great risk ofreinforcement corrosion.

Remmers surface protection sys-tems protect these concrete struc-tures from the ingress of moistureand damaging substances dissolvedin the water. They also prevent dam-age caused by frost and de-icingsalts; and, because they are CO2 re-sistant, they permanently protectagainst damage caused by corro-sion.

A rigid coating for surfaces sub-jected to vehicle traffic and heavymechanical loads is available in theform of an anti-slip coating accord-ing to OS 8 (DIN 13813). In addition,crack-bridging, anti-slip coatings ac-cording to OS 11b (DAfStb) are usedfor surfaces with foot and vehicletraffic.

REPAIRING CRACKS AND FILLING VOIDSRestoring Functionality

Cracks or voids that impair the func-tioning capacity of the building ele-ments can occur for the followingreasons:� Shrinkage� Change of static conditions

through settlement � Inherent stress in the building ele-

ment � Fluctuations in climate, particu-

larly frost� Reinforcement corrosion

Complete functionality can be restoredthrough different measures.

The ultimate aim of the repair, the typesof cracks and the course of the cracksare all decisive factors. Remmers injec-tion resins are suitable for a number ofapplications because of their extremelygood adhesive bonding capacity, theirhigh resistance to chemicals, and con-stant viscosity behaviour when in-jected.

Before the material can be injected intothe cracked area, the cracks must beplugged so that there is sufficient pres-sure to distribute the material and fillthe cracks. First the sides of the cracksmust be widened, after which they arefilled with a suitable plugging mortar.

Depending on requirements, materialsare available with different propertiesthat can provide economic solutions:� Extremely low-shrink, machine

applied mortar systems� Single or two component systems

with ultrafine mineral components

BALCONIES AND THEIR EXTREME LOADSWe Ensure a Holiday Setting at Home

For many people, their balcony is aplace to relax. And just as the archi-tecture of buildings varies greatly,balconies, terraces and loggias canalso vary widely in how they are con-structed. The defects and damagefound in these areas correspond tothe defects and damage found onother exterior building elements andare, in most cases, due to problemswith waterproofing. In addition, dam-age to the supporting structure canalso occur through warping or defor-mation caused by its inherent weightor traffic load, and/or damagecaused by moisture and thermalloads. Damage may also arisethrough faulty construction of thelayers such as poor thermal protec-tion but also because of the materi-als used. More than most otherbuilding elements, balconies must beable to withstand extreme loads.

Among the typical defects that arisebecause of the problems statedabove are cracks, detached tiles,leaks, open joints, damaged/dampscreed, infestation with moss andalgae, spalling concrete, dirt stains,efflorescence on tiles, corrosion ofsteel reinforcement, rust stains andcracked balcony balustrades. So before a balcony can be repaired,an exact determination of the causesand an analysis of the damage is nec-essary to define suitable repair meas-ures for the specific object. The Remmers Balcony and TerraceProgramme contains state-of-the-art,decorative system solutions, not onlyfor tile covers but also for coatingswith liquid plastics.

Climate loads� Temperature fluctuations of up to

70°C � Strong UV loads� Moisture through rain and snow � Frost loads� Because they are partially covered

A NEW, EXCITING FIELD OF WORKFrom Simple Fence Posts to the Berlin Wall

replacing the original concrete, thesimplest surface protection measureis to apply effective water repellingmeasures, e.g. with an invisible hy-drophobic impregnation agent.

Many other possibilities have alsobeen tested over the years, for exam-ple when the fence posts of the formerconcentration camp in Auschwitz andthe Kaiser-Wilhelm Memorial Churchin Berlin were restored.

In recent years, relatively young con-crete construction buildings havebeen declared “historically protectedmonuments”. When these buildingsneed to be restored, historical preser-vation takes precedence, which oftenmeans that normal rules for concreterepair cannot be followed. In thesecases, individual, object-specific solu-tions are required that must be dis-cussed with an approved curator.

Some of the typical damage found onconcrete is the same as that found onnatural stone facades:

� Organic and inorganic deposits onthe surface

� Sanding areas on the surface thathave become friable

� Use of inappropriate repair mortars� Pipes and gravel pockets� Cracks and open joints

Other types of damage are onlyfound on reinforced concrete andneed special treatment:� Rusting reinforcement� Spalling and cracks resulting from

corrosion of the reinforcement

Expereince in this area has shown thatit is possible to use existing productsystems from all areas of buildingpreservation. These concepts areoften alternatives to those specified inthe existing rules.

One example is the use of Remmersrestoration mortars for supplementingconcrete without static loads (loadingcapacity class M1).

Although it is not well known, practiceshows that the knowledge gainedfrom repairing natural stone can betransferred to the repair of concrete.The adjustment of the physical-me-chanical properties and colour ofRemmers restoration mortars hasbeen tested for many years. Localcoarse aggregates can also be usedwhich ensures that the old concretecan be matched almost exactly.

High moisture content is also respon-sible for the formation of corrosion.Particularly in the case of historical,early concrete structures, high car-bonation depths may be found be-cause of the highly porous consis-tency of the concrete. So along with

PROTECTION OF CONCRETE ELEMENTS IN CONTACT WITH THE GROUND

Highest Safety in a System

Remmers Kiesol System: � Prevents the ingress of water� Suppresses the penetration of

water vapour (sd value > 200 m)� Protects against water-related

corrosion� Helps the concrete to dry out and

increases resistance to heat trans-mission

� Improves the feeling of well-being

In Germany, waterproofing concreteelements in contact with the ground isnot regulated in RL-SIB nor in EN1504. However, concrete building ele-ments that are in contact with theground require special protection be-cause of the strong but very differentloads to which they are subjected. Forexample, for high-end utilisation ofcellar rooms for living purposes, a wa-terproofing system is a necessity.

To protect and waterproof these con-crete building elements, plastic-modified, bitumen waterproofingmaterials as well as flexible water-proofing grouts are particularly suit-able. This is because of: their resist-ance to chemicals; their flexible,crack-bridging properties; their easeof application; and their cost-effec-tiveness.
