SikaPlast®-240

WATER REDUCING CONCRETE ADMIXTURE WITH WORKABILITY RETAINING TECHNOLOGY

SikaPlast®-240 is a liquid high-range water reducing and workability retaining admixture for concrete that requires extended workability. SikaPlast®-240 is suitable for use in concrete mixes incorporating pozzolanic materials such as GGBS, PFA and microsilica.

  • Extended slump retention
  • Less sensitive to variations in cement and aggregate types
  • Improved cohesion properties
  • Improved early and ultimate strengths
  • Improved rheology and durability
  • Reduced drying shrinkage

Technical Information

Concreting guidance

The standard rules of good concreting practice for production and placing must be observed when using SikaPlast®-240 in concrete. Refer to relevant standards. Fresh concrete must be cured properly especially at high temperatures in order to prevent plastic and drying shrinkage. Use Sika® Antisol® products as a curing agent or apply wet hessian.

Application

Consumption

Recommended dosage

0.6 - 2.1 % by weight of binder depending on the mix design, raw materials, climatic conditions and concrete requirements.
Trial mixes must be performed to establish the exact dosage rate required.
