Product Overview

Sika ViscoCrete-5201 NS is a high-performance superplasticizing admixture based on modified polycarboxylate chemistry, engineered to deliver very high water reduction together with prolonged workability retention. By keeping cement particles dispersed for longer, it allows concrete to stay flowing and placeable through extended transport and handling while still achieving high strength, density and durability with reduced drying shrinkage. It is compatible with all cement types and is used in high-performance and high-strength concrete, ready-mix, self-compacting, precast, prestressed and pumped concrete for floors, slabs, foundations and reinforced walls. Space Arc Engineering, an authorized Sika distributor in India, supplies ViscoCrete-5201 NS to producers who need dependable slump life in warm conditions or over long hauls. Dosage and compatibility should follow trial mixes and the current Technical Data Sheet.
