SikaPlast®-400 CX

Water reducing and retarding superplasticizing admixture for concrete

SikaPlast®-400 CX 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®-400 CX 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®-400 CX acts by surface adsorption on the cement particles producing steric hindrance as well as electrostatic repulsion between the binder particles which results in higher dispersion, flow and retention. SikaPlast®-400 CX 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
