Sika® ViscoCrete®-625

Superplasticizer / High water reducer for fluid and high-performance concretes Sika® ViscoCrete®-625 is a new generation, non-chlorinated superplasticizer based on acrylic copolymers, specially formulated for the production of fluid concretes and high-performance concretes requiring excellent water reduction, great workability and high mechanical strengths. Description Sika® ViscoCrete®-625 acts by advanced dispersion of cement grains using a combined electrostatic and steric repulsion mechanism. This technology makes it possible to obtain homogeneous, very fluid or highly water-reduced concretes, with excellent cohesion and easy implementation on site. Areas of application Fluid and self-compacting concretes High performance concretes (HPC) Reinforced and prestressed concrete Pumped concrete Structural works requiring high durability Benefits Very strong water reduction Excellent fluidity and cohesion of concrete Significant improvement in mechanical resistance Reduction of porosity and shrinkage More compact and durable concretes Good compatibility 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 concrete plant are recommended in order to optimize the performance of the concrete.
