“KEM SUPLAST PCE 200 is an admixture of new generation based on modified polycarboxylic ether,” Deepak Kanitkar, GM & Head Technology, Construction Chemicals Division, Chembond Chemicals Ltd.
Chembond Chemicals Ltd. offers KEM SUPLAST PCE 200, a polycarboxylic ether (PCE) based, high range superplastering admixture for concrete. The product has been primarily developed for applications in high performance concrete where the highest durability and performance is required. It is free of chloride and low alkali. It is compatible with all types of cements.
Applications

High strength concrete
High performance concrete
Production of controlled rheology concrete
For attaining high workability without segregation or bleedingReady-mix and precast concrete
Concrete containing pozzolans such as microsilica, GGBFS, PFA as well as high-volume fly ash concrete
Advantages

Increase in early and ultimate strengths, higher e-modulus, improved adhesion to reinforcing and stressing steel
Excellent workability at optimum dosage.
Better resistance to carbonation and other aggressive atmospheric conditionsLower permeability – increased durability
Reduced shrinkage and creep
Elimination or reduction of vibration and reduced labour cost in placing.
Ensuring concrete reliabilityIt is a ready-to-use liquid which is dispensed into the concrete together with the mixing water. The plasticising effect and water reduction are higher if the admixture is added to the damp concrete after 70 to 90 per cent of the mixing water has been added. The addition of KEM SUPLAST PCE 200 to dry aggregate or cement is not recommended. Thorough mixing is essential and a minimum mixing cycle, after the addition of the KEM SUPLAST PCE 200 VM, of 60 seconds for forced action mixers is recommended
