Sika® ViscoCrete® SKY 8761 is a 3rd generation polymer based high performance superplasticizer for producing soft consistency concrete. Sika® ViscoCrete® SKY 8761 has no chloride content and meets the requirements of ASTM C 494 Type D & G.
Features:
Sika® ViscoCrete® SKY 8761combines different modes of actions. By adsorption on the surface of the fines and keeping them apart while the hydration is in progress, Sika® ViscoCrete® SKY 8761 effects the following concrete properties:
Improve mortar phase when using coarse sand.
Long slump keeping and high water reduction.
High flowability (considerably reduced placing and compacting work).
Faster evolution of early strength development.
Workability can be maintained up to 3 - 5 hours (still depends on admixture dosage, cement type, temperature).
Improved creep and shrinkage resistance characteristics.
When used at higher dosages, Sika® ViscoCrete® SKY 8761 can give extended working time.
