The excellent dispersion properties of RB-PC375 make it the ideal admixture for precast and ready mixed concrete where low water cement ratios are required. This property allows the production of very high early and high ultimate strength concrete with minimal voids and therefore optimum density in cold region. Due to the strength development characteristics the elimination or reduction of steam curing in precast works may be considered as an economical option.
RB-PC 375 is available in 220 kg drums and in 20 kg gallons.
RB-PC375 should be stored in original containers and at above 5 degree of Centigrade. If frozen gradually thaw and agitate until completely reconstituted.
RB-PC375 contains no hazardous substances requiring labelling. For further information refer to the Material Safety Data Sheet.
The normal dosage for RB-PC375 is between 0.2 and 0.8 kg per 100 kg of cement (cementitious material).
DIRECTION FOR USE
RB-PC375 is a ready to use admixture that is added to the concrete at the time of batching.
The maximum effect is achieved when the RB-PC375 is added after the addition of 50 to 70 % of the water. RB-PC375 must not be added to the dry materials.
Thorough mixing is essential and a minimum mixing cycle, after the addition of the RB-PC375, 60 seconds for forced action mixers is recommended.
