Sika® ViscoCrete® SKY 504
(former MGlenium SKY 504)
High range water reducing and superplasticizing admixture for concrete
Sika® ViscoCrete® SKY 504 is part of a range of latest generation superplasticizers engineered for ready-mix concrete.
Sika® ViscoCrete® SKY 504 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 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 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.
