Sikament® RB 1000

(former MasterRheobuild® 1000)

A SUPERPLASTICISING ADMIXTURE TO PRODUCE RHEOPLASTIC CONCRETE

Sikament® RB 1000 is a superplasticising admixture that contains a sulphonated polymer. It is chloride free and is specially formulated to impart rheoplastic qualities to concrete.

Rheoplastic concrete is a fluid concrete with a slump value of at least 200mm or higher that flows easily but at the same time is free from segregation and has the same water/cement ratio as that of a no-slump concrete without additive.

Sikament® RB 1000 has been formulated to meet the requirements of ASTM C494 for Type A & F & BS 5075 admixtures.

Sikament® RB 1000 is compatible with all cements meeting recognised international standards

  • Very high workability - Short placement time. Saves time and labour
  • High water reduction - High impermeability and strength. Improved durability
  • Superior cohesion - No segregation even at high workability. Excellent concrete quality
  • High early strength - Early demoulding. Shorter steam curing cycles
  • Low shrinkage and creep - Better dimensional stability
     
Compressive strength: Sikament® RB 1000 improves compressive strengths at all ages considerably compared to plain concrete with the same workability.

Shelf Life

12 months

Storage Conditions

Stored above freezing temperatures. If Sikament® RB 1000 freezes, thaw at 45 °F (7 °C) or above and completely reconstitute by mild mechanical agitation. Do not use pressurized air for agitation.

 

Application

Application Information

Dispensing

Use Sikament® RB 1000 as supplied after thorough stirring, without any dilution.

The addition of Sikament® RB 1000 to a dry mix is not recommended.

Sikament® RB 1000 provides optimal benefits when all materials have been batched and mixed.

Compatibility

Cement: For optimum performance, always use fresh cement since the reactivity of cement is reduced with ageing.

Aggregates: Use of properly graded, good quality, coarse aggregates and sand helps to achieve higher impermeability and strength.
Consumption

Consumption

Dosage depends upon the mix design, the ambient conditions and the degree of water reduction and workability required. Typical dosage used is 0.7- 1.2L per 100kg of cementitious materials.
Site trials are recommended to fix the dosage.
