Sikament® RB 2000 M

A HIGH RANGE MELAMINE BASED SUPERPLASTICISER

Sikament® RB 2000 M is a chloride free, admixture based on melamine formaldehyde, formulated for the production of rheoplastic concrete. Sikament® RB 2000 M available as a liquid  form which can used for the production of rheoplastic concrete. A rheoplastic concrete is a fluid, but cohesive mix with a slump value of at least 200 mm. It is virtually self compacting, but at the same time free from segregation and with a water/cement ratio as a noslump concrete with an admixture. Sikament® RB 2000 M is suitable for use in hot and tropical climatic conditions.

  • Translucent color enables use with white cement concrete
  • Enables production of highly impermeable, dense concrete with enhanced durability
  • Enables higher strength and high workability concrete with normal cement contents
  • Enables earlier demoulding of precast units
  • Can be used to produce self compacting flowing concrete which requires little to no vibration

Technical Information

Concreting guidance

The standard rules of good concreting practice for production and placing must be observed when using Sikament® RB 2000 M 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® RB 2000 M is suitable for mixes containing all types of cement and supplementary cementitious materials such as: Microsilica (Silica Fume), Fly Ash (PFA), GGBS (ground granulated blast furnace slag) and the following Sika products:
▪ SikaPump®
▪ Sika®FerroGard®
▪ SikaFume®
▪ SikaFiber®
▪ Sika® Aer
▪ Sika® Stabilizer
▪ SikaControl®
We recommend to perform trial mixes to establish the required performance when combining Sikament® RB 2000 M with the above products or other admixtures. Sikament® RB 2000 M should not be premixed with any other admixtures. If other admixtures are to be used, those should be dispensed separately. Please consult our Sika Technical Department for further assistance.

Dispensing

Sikament® RB 2000 M is a ready-to-use admixture to be added to the concrete as a separate component. Optimal result is obtained if Sikament® RB 2000 M is poured into the concrete mix right after the addition of the first 80 % of the mixing water, i.e. when all solids are wetted. Avoid adding the admixture to the dry aggregates.
Consumption

Recommended dosage

Sikament® RB 2000 M is normally dispensed at a rate of 0.5 – 3.0 Iitres per 100 kg of total binder. Other dosages may 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.
