Sika® ViscoCrete®-225 P is a high-performance superplasticizer and water reducer in powder form based on Sika® ViscoCrete® polycarboxylate polymer technology. High water reduction capacity High sulphate tolerance Compatible with other additives, e.g. citric acid Usage Sika® ViscoCrete®-225 P is formulated for applications in systems with high calcium sulphate content or pure gypsum binders. The product is especially suitable for the production of dry-mixed mortars and concrete for applications like: Floor screeds, self-leveling screeds and underlayments Grouts, non-shrink grouts, repair mortars, tile adhesives Building plaster, render, stucco, bonding/filling compound, molding plaster, dental & medical plaster Sika® ViscoCrete®-225 P can be used in the following binder systems: Calcium sulfphte binders (α- and β-hemihydrate, natural/thermal/synthetic anhydrite) Ternary compounds (Portland cement + calcium aluminate cement + calcium sulphate) Portland cement and cement blends, especially cement with high C3A, sulfate and alkali content Advantages Sika® ViscoCrete®, Sika´s polycarboxylate technology, works based on a combination of electrostatic forces and steric repulsion effects. Thus, solid particles can be effectively dispersed.Sika® ViscoCrete®-225 P is adsorbed onto the surface of the binder particles and due to repulsive forces from the effect known as steric hindrance, the solid binder particles are very effectively dispersed in the mix. The benefits of Sika® ViscoCrete®-225 P include, but are not limited to the following: High water reduction, resulting in high density and strength
