Field of Application

Producing highly flowable concrete
Performing pre-stressed concrete
Faster concrete placement
Industrial high strength flooring systems
Concrete pumping with least depreciation
Performing highly rein forced concrete structures
Performing all pre-cast and cast in place concrete structures
Easy placement in structures with small and unsymmetrical area
Producing highly strength concrete through reducing the ratio of water to cement

Properties and Effects

Increasing concrete slump
Increasing final strength by 40% of the strength of the original sample
Reducing water content under constant flowability condition by 30%
Reducing cement percentage under constant strength condition by 15%
Reducing aggregate tendency to segregation
Increasing integrity of concrete
Improving pumpage and reducing the depreciation of tools and equipment
Increasing impermeability
Increasing bond strength of concrete to steel
Increasing resistance to thawing and freezing cycles, and improving durability of concrete
Reducing the consumption of condensation energy


Depending on the required strength and workability and ambient temperature, use BC20 up to 0.3 to 0.8% of cement weight

Instruction of use

To achieve the optimal result, after mixing ingredients add BC20 to the mixture and continue mixing for 2 minutes

Technical Observation and application

The overuse of the admixture increases the flowability and reduces the strength of concrete
The optimal dosage rate may be obtained by trial mixes
When simultaneous use of several admixtures in concrete mix is required, consult Research Center of Beton Chimie
BC20 is compatible with all kind of Portland cement
Never add the product to dry materials
