PREFACE

❒ Concrete

The operating loads which can be applied to anchors generally depend on the mechanicalproperties of the base material. In the case of concrete, it is customary to refer to itscompressive strength.

According to Eurocode 2, the compressive strength of concrete is expressed in terms ofcharacteristic strength defined as being the strength value below which a maximum of 5% of thewhole possible strength measurements of the specified concrete must be located.

The strength must be determined according to ISO 4012 on cubic specimens 15 x 15 x 15 cm(called fck,cube), or on cylindrical specimens 16 x 32 cm (called fck,cyl.) 28 days old, complyingwith ISO 1920 and manufactured and stored according to ISO 2736.

Concrete is classified according to its compressive strength which is based on the classificationper strength measured on cylinders as indicated in Eurocode 2. For information, the table belowgives the correlation between characteristic values and average strength on cylindrical andcubic specimens in MPa.

1.1 - Definition and composition of EPOXY ceramic 6 resin

EPOXY CERAMIC 6 is made up of two components contained in a single cartridge with twoidentical cylinders.

- The first cylinder contains epoxy resin (100%)

- The second cylinder contains hardener.

The following table summarises the characteristics of the components:

1.2. Operating principle

The mixture obtained by mixing the 2 components (epoxy resin + hardener) is injected in a suitable hole from which all dust has been removed. Generally speaking, the quantity of mixtureto be injected should be equivalent to 50% of the volume of the hole.

The element to be fixed is inserted in the hole by hand, turning it back and forth, until it reachesthe end of the hole. The element should be clean and free from oil and grease. In this way theEpoxy Ceramic 6 will be spread along the wall of the hole and completely envelop the elementto be fixed, bonding it to the wall.

The Epoxy Ceramic 6 gradually hardens and solidly bonds the element to the base material. Theresin should come back along the hole until it is at least flush with the wall surface.

The rate of hardening depends on the ambient temperature.

The minimum and maximum temperatures of the base material during installation are 4° and52°C.

NOTA: *These waiting times correspond to a safety factor of approximately 2 on the service loadand 1,5 on the ultimate load. All those hardening time have to be doubled for anchoring in humidconcrete.

1.3 - Suitable base materials

The present specification deals with the use of Epoxy Ceramic 6 in healthy reinforced or plainconcrete in a horizontal position or perpendicular to the ground. In the case of rendered concrete,the thickness of the render should be disregarded when calculating the anchorage depth.

It is possible to use Epoxy Ceramic 6 in cracked concrete or hollow materials and other solidconstruction materials, but the values indicated in this specification must not be used. Pleaseconsult us regarding the specific tests to be conducted in such cases.

1.4 - Field of use

This specification aims at the use of EPCON resin for anchoring of stell reinforcment with the diameter8 to 40 mm for concrete with characteristic strength on cylindrical specimens at 28 days of 20 Mpaat the least.

This resin allowed to obtain strong fixings where the hole diameter is significantly larger than thediameter of the rebar to be fixed (very limited shrinkage < 0,05%). See §5.

1.5 - Resistance of SPIT EPCON resin to chemical agents

The chemical resistance has been established by exposing resin samples to various substances.The resistance of the samples was established by visual inspection and classified in 3 levels(resistant, sensitive, not resistant).The various substances tested and the resistance of the SPIT EPCON resin are given inappendix 1

1.6 - Resistance of the SPIT EPCON resin to temperature

1.6.1 - Freezing / thawing cycles

Freezing/thawing cycle tests were carried out in accordance with the ICBO AC58,ASTM E 1512 and ASTM E 488 specifications. The fixing was subject to 50 freezing/thawing cycles with holding times of 3 hours at temperatures of - 23°C et + 40 °C.These positive and negative temperature variations had no effect on the performance ofthe SPIT EPCON fixing.

1.6.2 - Resistance as a function of temperature

Temperature tests were performed at 0°C up to 140°C. For the various temperaturestested, extraction tests were carried out after the fixing had been exposed in an oven at aconstant temperature for 24 hours.The effect of the temperature is given in the following graph:

2.1 - OFFICIAL QUALIFICATION TESTS

CERAMIC 6 SPIT EPCON SYSTEM has been tested by an official laboratory according to thefollowing standards:

- P 18-831 of April 1993: binder or synthetical resins base anchoring products. Pullout test.

- P 18-836 of July 1993: synthetical resins base anchoring products. Creep test.

These official tests have been carried out on humid base materials and at 23°C in groundposition and wall position after 7 days of anchoring.

The product has been accepted to the NF mark as anchoring product in classification 4according to P 18-822 standard.

2.2 - Other qualification tests

2.2.1 - A pullout test has been carried out on humid base material according to P 18-831standard by the same laboratory (report n° 94/075/A) after only 2 days of the anchoring.Results are according to admission requirements to NF mark.

2.2.2 - SPIT laboratory which is COFRAC accredited has carried out the same types oftests than above on dry base material and according to P 18-831 and P 18-836 standardsat 23°C in perpendicular position to the ground after 1 day of the anchoring = Results areaccording to admission requirements to NF mark.

2 - NF MARK "SPECIAL PRODUCTS" FOR HYDRAULIC CONCRETEBUILDING

We have determined by experiment the mini anchoring depths for different strength of concrete inorder to obtain the mini. rupture strength according to NFA 35016 standard. The mini. drillingdiameter has been determined in order to enable the free introduction of the rebars in drilling.

The following table gives results (in mm) for rebar steel Fe E 500.

NOTA: With steel Fe E 400, anchoring depth and tensile efforts have to be reduced by 20 %.

4.2 - Anchoring depth calculation

Considering the hypothesis proved during the tests that the ultimate adhesive strength of resinversus concrete is at least equal to the one of high adhesion rebar in concrete, anchoringdepth (ls) in mm can be given by the equality :

As.fe = u.ls. τsu (1) (see BAEL 91 page 44)

or As = Nominal cross-section of rebar in mm2

fe = Elastic limit of rebar in N/mm2

u = Π Øf (drilling diameterà in mmτsu = Adhesive strength = 0,6.ψ2s.ftj (in N/mm2)ψs = Fixing coefficient = 1 for plain rounds and 1,5 for high adhesion rebarsftj = Characteristic tensile strength of concrete in N/mm2 or Mpa

The ultimate load for rebar is As.fe with γs = factor of security = 1,15γs

The equation (1) becomes:

Ultimate load (in Newton) : Π Øf.ls.0,6.ψ2s.ftj.1γs

Ultimate load : Π.0,6.1,52.Øf.ls.ftj = 3,69.Øf.ls.ftj

1,15

ls (mm) = Ultimate load (N) .3,69.Øf (mm) ftj (MPa)

Limit of this formula

- Drilling diameter cannot exceed 3 times the nominal diameter of rebar: Øf ≤ 3 rebar Ø.- The useful anchoring depth should be ≥ 12,5 times rebar Ø without ultimate load reduction

and equal to 10 times rebar Ø for a reduction of this load by 20 %.- The maxi. anchoring depth will be limited to 900 mm.- In any case, we cannot exceed 2 cartridges per fixing.

5 - DIMENSIONING TABLE OF ANCHORING

These tables are the application of the formula § 4.2. taking into account the limit of use.

For HA Fe E 500 rebars and for a possible maxi ultimate load per rebar diameter, they give :

- The anchoring depth for a certain drilling diameter and concrete strength- The theoritical number of fixings per EPCON cartridge

For an ultimate load below the maxi ultimate load, anchoring depths can be reduced in the same proportion without being lower than 10 times the rebar Ø.

6 - INSTALLATION

7 - VALIDITY OF SPECIFICATIONS END OF JUNE 2008

Drill a hole according to the selected diameter(tables of dimensions of anchoring). The holmay be drilled with a diamond bit, but rebarlocation must be determined in order to avoidcutting them.

Carefully brush the surface ofthe hole with a metal brush.

Blow the dust out of the hole.NB:The hole may also becleaned with a jet of water.

Inject from the bottom of the hole, graduallyfilling it until 50 % fult.

Insert the rebar by hand with a twisting motionuntil the end of the hole is reached. The rodmust be clean and free from oil and grease.Check that the hole is well filled (no airbubbles). A slight excess should emerge.

Wait for the resin to harden before applying theload (see table page 3).
