SikaPlast®-279 AE
WATER REDUCING AND RETARDING CONCRETE ADMIXTURE
SikaPlast®-279 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.
SikaPlast®-279 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.
SikaPlast®-279 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.
SikaPlast®-279 AE provides the following beneficial properties:
SikaPlast®-279 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
