Sikament® RB 1100

(former MRheobuild 1100)

HIGH RANGE WATER-REDUCING CONCRETE ADMIXTURE

The basic components of Sikament® RB 1100 are synthetic polymers which allow mixing water to be reduced considerably and concrete strength to be enhanced significantly, particularly at early ages. Sikament® RB 1100 is a chloride free product.

Sikament® RB 1100 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

▪ Walls
▪ Columns
▪ Piers
▪ Slender components with dense reinforcement
It is also used as a water-reducing agent leading to high early strength concrete for:
▪ Pre-cast concrete elements
▪ Pre-stressed concrete
▪ Bridges and cantilever structures

Technical Information

Concreting Guidance

The standard rules of good concreting practice for production and placing must be observed when using Sikament® RB 1100 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

Dispensing

Sikament® RB 1100 is a ready-to-use admixture to be added to the concrete as a separate component. Optimal result is obtained if Sikament® RB 1100 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.

   

Alternatively, when using Sikament® RB 1100 to produce flowing concrete at site using ready-mix trucks, it can be added to the concrete via the feed hopper at the rear of the truck. Mix before discharge for 3 minutes at 10rpm to produce a fully homogenous mix.
When using Sikament® RB 1100 to obtain very high early strengths, advantage must be taken of its water reducing properties.

Compatibility

Sikament® RB 1100 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 1100 with the above products or other admixtures. Please consult our Sika Technical Department.

 
Consumption

Recommended Dosage

0.8 - 1.5 % 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.
