Sika® ViscoCrete® SKY 504 AE

(formerly MGlenium SKY 504AE)                                                                                                                                                                                                                                                                                            Water reducing and retarding superplasticizing admixture for concrete

Sika® ViscoCrete® SKY 504 AE is part of a range of latest generation superplasticizers engineered for ready-mix concrete.
Sika® ViscoCrete® SKY 504 AE is based on unique polymers with long lateral chains. This greatly improves cement dispersion. At the start of the mixing process the same electrostatic dispersion occurs but the presence of the lateral chains, linked to the polymer backbone, generate a steric hindrance which stabilises the cement particles capacity to separate and disperse.
This mechanism provides flowable concrete with greatly reduced water demand.
Suitable for use in hot and tropical climatic conditions

Sika® ViscoCrete® SKY 504 AE provides the following beneficial properties:
▪ Substantial improvement in workability without increased water
▪ Low risk of segregation
▪ Normal set without retardation (within the dosage limit)
▪ Improved density and surface finish
▪ Improved water tightness
▪ Excellent solution for continuous concrete casting of deep elements
▪ Does not contain chlorides or other steel corrosion promoting ingredients
▪ Sika® ViscoCrete® SKY 504 AE may be used in combination with Sika® Stabilizer. The technology produces advanced self-compacting concrete, without the aid of vibration. For economic, ecological and ergonomic ready-mix concrete production.
