SikaPlast®-1300 HEV-3

Water reducing and retarding superplasticizing admixture for concrete

SikaPlast®-1300 HEV-3 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®-1300 HEV-3 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®-1300 HEV-3 acts by surface absorption 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®-1300 HEV-3 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

Technical Information

Concreting Guidance

The standard rules of good concreting practice for production and placing must be observed when using SikaPlast®-1300 HEV-3 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®-1300 HEV-3 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®-901, SikaFume®, SikaFiber®, Sika Aer®, Sika® Stabilizer, Sika®-1 WT, Sika® WT-10
We recommend performing trial mixes to establish the required performance when combining SikaPlast®-1300 HEV-3 with the above products or other admixtures. Please consult our Sika Technical Department.

Dispensing

SikaPlast®-1300 HEV-3 is added to the gauging water or simultaneously poured with it into the concrete mixer at the batching plant.
Do not add SikaPlast®-1300 HEV-3 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, up to 2.0 %, by weight of binder 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.
