Materials use in precast structures

• Concrete• Steel reinforcement

• Structural steel and bolts

• Non- cementitious material

Concrete

Precast Concrete is a construction product producedby casting concrete in a reusable mold or "form" whichis then cured in a controlled environment, transportedto the construction site and lifted into place. Incontrast, standard concrete is poured into site-specicforms and cured on site. Precast stone is

distinguished from precast concrete by using a neaggregate in the mi!ture.



•Steel reinforced concrete is concrete in whichsteel reinforcement bars, plates or bers have been

incorporated to build up a material . In industrialiedcountries, nearly all concrete used in construction isreinforced concrete. #here are a number of buildingmaterials that have been found to be e!ceptionalwhen it used in the construction of buildings

Steelreinforcement

•Structural steel is steel construction material, a prole,formed with a specic shape or cross section and certainstandards of chemical composition and mechanical properties.Structural steel shape, sie, composition, strength, storage, etc.,

is regulated in most industrialied countries.•Structural steel members, such as I-beams.

Structural steel



Fibre reinforced concrete $%&C' is concrete containing brous

material which increases its structural integrity. It contains shortdiscrete bres that are uniformly distributed and randomlyoriented. %ibres include steel bres, glass bres, synthetic bresand natural bres. (ithin these di)erent bres that character ofbre reinforced concrete changes with varying concretes, brematerials, geometries, distribution, orientation and densities.

Non cementitiousmaterial

Glass Fiber Reinforced Concrete $GFRC' is a type of berreinforced concrete. *lass ber concretes are mainly used ine!terior building fa+ade panels.

ecient solutions.

•&eliable - %itting of precast is a fast process and not sub/ect to the same

weather dependency as traditional construction methods with an average

house being covered within a few hours.

2ollow core Composite%loors

• 2ollow core Composite %loors combine the benets of ourstandard 2ollow core unit, with a Structural #opping, !ed onsite, to give a greater load bearing capacity.

• 2ollow Composite %loors use 2ollow core units with astructural concrete topping that provides improved loadcapacity.

• 2ollow core Composite %loor can be designed in theunwrapped or partially propped condition to suit the particular

re1uirements of construction. #his maes the product well-suited to industrial developments, tall buildings, car pars,

• Suitable for use in all types of building these pre-stressed unitsfeature a series of voids that run the length of each section thus

reducing weight and improving thermal performance.

Solid Composite %loorsSolid Composite %loors are a combination of solid prestressed

concrete units with a structural concrete topping which is placedafter the solid slabs have been erected.
