Sika® ViscoCrete®-630 RMX

Superplasticizer / High water reducer for ready-mixed concrete with high regularity Sika® ViscoCrete®-630 RMX is a new generation, non-chlorinated superplasticizer based on acrylic copolymers, specially designed for ready-mixed concrete (BPE / RMX) requiring excellent regularity, durable workability and high mechanical performance, even during prolonged transport. Description Sika® ViscoCrete®-630 RMX acts by advanced dispersion of cement grains using a mechanism combining electrostatic and steric repulsion. This technology guarantees homogeneous concrete, stable and easy to pump, with very good consistency maintenance over time, particularly suited to the constraints of BPE plants. Areas of application Ready-mixed concrete (BPE / RMX) Concrete pumped over long distances Concretes poured in hot weather Common and technical structural concretes Projects requiring high consistency of quality Advantages Significant water reduction Excellent maintenance of workability Very good regularity of fresh concrete Reduction of the risk of segregation and bleeding Improvement of mechanical resistance More compact and durable concretes Compatible with the majority of cements Use The dosage depends on the type of cement, aggregates, concrete formulation and desired performance. Prior tests in a BPE plant are recommended in order to determine the optimal dosage.
