Sika® Plastiretard

Sika® Plastiretard is a versatile setting retarder for concrete, usable in all types of concrete. Depending on the dosage used, it also acts as a water reducer, improving the performance of concrete both in the fresh and hardened states. Advantages over fresh concrete Significantly improves workability, even with reduced mixing water Ensures homogeneous dispersion of cement in the mass Limits segregation and increases thixotropy of concrete Facilitates implementation, particularly in hot weather or for transported concrete Advantages of hardened concrete Increases final mechanical resistance Increases compactness and improves waterproofing Reduces shrinkage and creep Contributes to better durability of structures Areas of application Concretes cast in hot climates Ready-mixed concretes Concrete foundations, slabs and common works Projects requiring delayed setting time and better workability
