CONMIX manufactures an impressive range of construction chemicals that comply with international standards.

Customised Concrete:Admixtures make it easy

oncrete is the core componentof every structure. Concretehas evolved over a period oftime not only in its constituent

nature but also its utility. Modern day con-crete has to comply with many stringentparameters set by structural designersand architects. Concept of commercialready mix business has raised the expecta-tions of concrete performance in terms oflonger duration of slump retention andeasy pumpability without segregation andbleeding for tall structures.

Concrete had to satisfy only the com-pressive strength as a main parameter inthe past. But today, concrete has to alsomeet other durability parameters likeleast levels of water penetration, rapidchloride permeability, water absorption,etc. Consultants and designers employ var-ious international standards like BS EN12390-8, BS 1881-208, ASTM C1202, ASTMC109, BS 6319-3, etc. to govern the perform-ance of fresh and hardened concrete.

Technological advancement

Above scenario has compelled concreteproducers to design the concrete using latest technology with utmost care.Concrete mainly constitutes fine aggre-gates, course aggregates, water and

cement as a binder which have to be com-bined in optimal proportions to obtainbest performance. Many a time, quality oflocally available materials puts limits onthe concrete technologist to have best qual-ity concrete or to meet increased stringentperformance levels.

Construction chemicals are beingextensively used to enhance the quality ofconcrete to fulfil the pre set performancetarget which is difficult to attain other-wise. MegaFlow SP1 range of concreteadmixtures help in achieving high slumpof 160mm with water reduction of 30%.These admixtures are a boon to precastindustry where early strength at 12 to 14hours is a governing factor for fast rota-tion of the moulds thereby increasing theproductivity. MegaFlow SP4 range ofconcrete admixtures help in maintainingthe pumpability of concrete with morethan 120mm slump and for extended traveltime up to two hours without setting ofthe concrete. Modern day concrete whichcontains combination of cement, microsilica, fly ash or GGBS, etc. calls for specially designed admixtures likeMegaFlow SP402.

congested steel reinforcements andreduced noise and energy level require-ments at sites have called for self compact-ing concrete. MegaFlow 2000 range ofpoly carboxylic based hyper plasticisershelps concrete technologists to design andexecute self compacting concrete withease. These admixtures help in designingconcrete with high strength of 80 MPa andalso completely avoid noisy mechanicalcompaction.

Water holding structures like watertanks, swimming pools, dams, canals,deep pile foundations etc. require watertight concrete. MegaAdd WL range ofadditives helps in designing concrete withleast water penetration at high pressures.
