Sikament® RB 858 C 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 858 C with the above products or other
admixtures. Please consult our Sika Technical Department.

The standard rules of good concreting practice for production and placing
must be observed when using Sikament® RB 858 C 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.

Sikament® RB 858 C is a ready-to-use admixture to be added to the concrete
as a separate component. Optimal result is obtained if Sikament® RB 858 C 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.

0.8 - 2.0 % by weight of binder
Other 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.
