SikaPlast®-2600

High performance water reducing and retarding concrete admixture

SikaPlast®-2600 is a third generation polycarboxylate based superplasticizer for concrete. It has been developed for use in ready mixed concrete giving extended slump retention and high strength development of normal grade concrete mixes.
SikaPlast®-2600 is suitable for use in concrete mixes containing microsilica and other pozzolanic materials such as GGBS and fly ash.
Suitable for use in hot and tropical climatic conditions.

SikaPlast®-2600 acts by surface absorption on the cement particles producing steric hindrance as well as electrostatic repulsion between cement particles which results in higher dispersion, flow and retention. SikaPlast®-2600 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 continuous concrete casting for 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®-2600 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®-2600 may be combined with all types of Portland cement and the following Sika products:

  • SikaPump®
  • Sika® FerroGard®-901
  • SikaFume®
  • Sika-Aer®
  • Sika® Control-40 (stabilizer)
  • Sika®-WT 1

We recommend to perform trial mixes to establish the required performance when combined with the above products. Please consult our Sika Technical Department.

Dispensing

SikaPlast®-2600 is added to the gauging water or simultaneously poured with it into the concrete mixer at the batching plant. Do not add SikaPlast®-2600 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.
