Product Overview

Sika ViscoCrete-5138 is a high-performance superplasticizing admixture formulated from a modified polycarboxylate base to create free-flowing concrete with excellent water reduction and workability retention. Its advanced dispersion action separates cement particles so mixes flow and self-level at reduced water content, then harden into dense, durable, high-strength concrete with lower drying shrinkage. The admixture is well matched to floors, slabs and foundations, slender reinforced sections, walls and columns, and to high-performance, high-strength, ready-mix, self-compacting and pumped concrete. Space Arc Engineering, an authorized Sika distributor in India, supplies ViscoCrete-5138 to ready-mix producers and contractors who need consistent flow over time without compromising strength. As with all admixtures, dosage and compatibility should be validated by trial and the current Technical Data Sheet.

Features & Benefits

• Very high water reduction for high-strength, low-permeability concrete
• Sustained workability retention keeps mixes placeable during transport and handling
• Free-flowing rheology improves placing, compaction and surface finish
• Denser matrix enhances durability against aggressive exposure
• Reduced drying shrinkage lowers the likelihood of cracking
• Suited to self-compacting and pumped concrete in complex pours

Technical Highlights

Applications

• High-strength concrete for towers, transfer slabs and core walls
• Self-compacting concrete in slender, densely reinforced members
• Ready-mix supply requiring reliable workability over longer haul distances
• Infrastructure foundations and water-retaining structures needing low permeability
• Pumped concrete for high-rise and large-volume commercial pours
