Product Overview

Sika® ViscoCrete®-2004 NS is a high-performance superplasticising admixture formulated as an aqueous solution of modified polycarboxylate. It imparts very high workability with improved workability retention and permits a large reduction in water content, producing a uniformly cohesive, free-flowing concrete of high quality through superior dispersion and rheology control. The result is concrete with improved strength, density and durability, better cohesion and reduced drying shrinkage. Its strong water reduction combined with extended slump life makes it well suited to high-strength, ready-mix, self-compacting, precast, prestressed and pumped concrete, including pours that need to stay workable during transport. Space Arc Engineering, an Authorized Project Distributor for Sika in India, supplies ViscoCrete®-2004 NS in drums and bulk, backed by mix-design support for ready-mix and infrastructure projects.
