Sikament® RB 1044

(former MasterRheobuild® 1044)

Optimised Superplasticising Admixture for producing Rheoplastic Concrete

Sikament® RB 1044 is a ready to use, liquid admixture designed to produce rheoplastic concrete. Rheoplastic concrete is typically defined as fluid concrete with slump value of >200 mm that flows easily but at the same time is free from segregation. Sikament® RB 1044 contains no added chloride.

• High workability for shorter placement time 
• High water reduction to produce high impermeability and strength leading to improved durability 
• Superior cohesion with no segregation even at high workability leading to excellent concrete quality 
• Higher early stregth for early de-moulding 
• Low shrinkage and creep for better demensional stability

Application

Application Information

Dispensing

The addition of Sikament® RB 1044 into dry mix is not recommended. Sikament® RB 1044 can be dosed either at the batching plant or on-site. Introduce Sikament® RB 1044 at the specified dosage directly into the mixer through a dispenser along with the mixing water when the concrete is thoroughly wetted (i.e., after adding at least 75% of the mixing water) and mix for at least 2 minutes. For on-site dosing, mix for at least 2 minutes after the addition.

Compatibility

Sikament® RB 1044 may be combined with many other Sika products. Trials must always be carried out before combining products in specific mixes. Contact Sika Technical Services for additional information and any specific combinations. 
Sikament® RB 1044 is compatible with all types of Portland Cement, including SRC type and Hydraulic Cement.
Consumption

Recommended dosage

Dosage of Sikament® RB 1044 depends upon the mix design, the ambient condition and the degree of water reduction and workability required. Typical dosage used is 0.6 – 2.0 litres per 100 kg of total cementitious materials. Other dosages may also be used depending on the mix design and ambient condition. Therefore, in many cases it is advisable to carry out trial mixes.
