Sika ViscoCrete®-522 RMX

Superplasticizer / High water reducer for ready-mixed concrete (BPE) Sika® ViscoCrete®-522 RMX is a new generation, non-chlorinated superplasticizer based on acrylic copolymers, specially developed for ready-mixed concrete (RMX / BPE). It ensures excellent workability, high water reduction and optimal stability of the concrete during transport and installation. Description Sika® ViscoCrete®-522 RMX acts by advanced dispersion of cement particles using an electrostatic and steric repulsion mechanism. This technology makes it possible to obtain homogeneous concretes, easy to pump, with good maintenance of workability, even during prolonged transport times. Areas of application Ready-mixed concrete (BPE / RMX) Pumped concrete Concrete poured in hot climatic conditions Common and technical structural concretes Construction sites requiring good consistency consistency Advantages Significant water reduction Excellent workability and pumpability Good consistency maintenance over time Reduction of the risk of segregation and bleeding Improvement of mechanical resistance More compact and durable concrete Compatible with the majority of cements Use The dosage depends on the type of cement, the concrete formulation and the desired performance. Prior tests in a BPE plant are recommended in order to determine the optimal dosage.
