SikaPlast®-200 S

Mid-Range water reducing and retarding concrete admixture

SikaPlast®-200 S 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®-200 S 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®-200 S 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®-200 S provides the following beneficial properties:
  • Substantial improvement in workability without increased water
  • Low risk of segregation
  • Low air content
  • 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 therefore may be used for reinforced and pre-stressed concrete construction

Technical Information

Concreting guidance

The standard rules of good concreting practice for production and placing must be observed when using SikaPlast®-200 S 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

Application Information

Compatibility

SikaPlast®-200 S may be combined with all types of Portland cement (OPC and SRC), concretes containing pozzolanic materials such as; GGBS,
PFA, micro-silica and the following Sika products:

  • SikaPump® 
  • Sika® FerroGard®
  • SikaFume®
  • SikaFiber® 
  • Sika® Aer
  • Sika® Stabilizer 
  • Sika®-1 WT 
  • Sika® WT-10

We recommend to perform trial mixes to establish the required performance when combining SikaPlast®-200 S with the above products or other
admixtures. Please consult our Sika Technical Department.

Dispensing

SikaPlast®-200 S is added to the gauging water or simultaneously poured with it into the concrete mixer at the batching plant. Do not add SikaPlast®-200 S directly to the dry mix. For optimum utilization of its high water reduction property we recommend thorough mixing at a minimal wet mixing time of 60 seconds.The addition of the remaining gauging water (to fine tune concrete consistency) may only be started after two-thirds of the wet mixing time to avoid surplus water in the concrete.
Consumption

Recommended dosage

0.8 - 1.6 % by weight of binder.

Higher dosages by weight of binder, up to 2.0 %, can be used depending on the mix design, raw materials, climatic conditions and concrete requirements. Trial mixes must be performed to establish the exact dosage rate required.
