Sikament®-300 R

Superplasticizing admixture for concrete

Sikament®-300 R is the retarded version of Sikament®-300, a highly effective dual action liquid superplasticiser that imparts excellent slump retention for prolonged periods.
Suitable for use in hot and tropical climatic conditions.

Sikament®-300 R provides the following properties:
As a Superplasticiser:
  • Workability is greatly improved
  • Concrete is placed easily
  • Especially suitable for slender components with densely packed reinforcement
  • Concrete requires less vibrating
  • Improved cohesion of the concrete mix significantly reduces the risk of segregation and allows greater time for placement
 
As a Water Reducer:
  • Impressive water reduction capability
  • Final strength improvement

Technical Information

Concreting Guidance

The standard rules of good concreting practice for production and placing must be observed when using Sikament®-300 R 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

Sikament®-300 R 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 to perform trial mixes to establish the required performance when combining Sikament®-300 R with the above products or other admixtures. Please consult our Sika Technical Department.

Dispensing

Sikament®-300 R is added to the gauging water or simultaneously poured with it into the concrete mixer at the batching plant.
Do not add Sikament®-300 R 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

0.4 - 1.6 % by weight of binder.
Higher dosages 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.
