Sikament® RB 1088

(former MasterRheobuild® 1088)

A HIGH RANGE WATER-REDUCING ADMIXTURE IN LIQUID FORM FOR RHEOPLASTIC CONCRETE

Sikament® RB 1088 is a water- soluble, sulphonated polymer-based admixture which allows mixing water to be reduced considerably and concrete strength to be accelerated significantly, particularly at early ages. It contains no chlorides and meets the requirements of ASTM C494 Type F for high range water-reducing admixtures.
Sikament® RB 1088 improves compressive strengths at all ages considerably compared to plain concrete with same workability.

  • Flowable
  • Non-segregating
  • High strength
  • High impermeability
  • Greater durability
  • Dimensional stability
  • Increase resistance of air-entrained concrete to damage due to freezing, thawing and scaling from de-icing salts

Usage

  • Use with all cements and admixtures meeting ASTM, AASHTO, UNI and BSI specifications.
  • Use with MB-VR air entraining agent whenever concrete is required to withstand freeze-thaw cycling.

Storage Conditions

Stored at temperatures above 5°C, in tightly sealed original drums. If found to be frozen, thaw it and reconstitute by stirring.

Application

Application Information

DISPENSING

Sikament® RB 1088 is introduced into the mixer together with water. The plasticising effect or water reduction is higher if the admixture is added to the damp concrete after 50-70% of the water has been added. The addition of Sikament® RB 1088 to dry aggregate or cement is not recommended, as it lowers the plasticising effect or water reduction.

 
Consumption

Recommended Dosage

Sikament® RB 1088 is normally dispensed at a rate of 700 – 1500mL per 100kg of cementitious material. Other dosages may also be used depending on the specific working condition.
