Sika® ViscoCrete®-7750 AE
HIGH RANGE WATER REDUCING / SUPERPLASTICIZING ADMIXTURE FOR CONCRETE
Sika® ViscoCrete®-7750 AE is a polycarboxylate based superplasticizer developed particularly for use in ready mixed concrete to give extended slump retention and high strength development of normal grade concrete mixes.
Sika® ViscoCrete®-7750 AE is suitable for use in concrete mixes incorporating pozzolanic materials such as GGBS, PFA and microsilica.
Suitable for use in hot and tropical climatic conditions.
Sika® ViscoCrete®-7750 AE acts by surface adsorption on the cement particles producing steric hindrance as well as electrostatic repulsion between cement particles which results in higher dispersion, flow and retention.
Sika® ViscoCrete®-7750 AE provides the following beneficial properties:
