Description

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 25% of the strength of the original sample,
Reducing water content under constant flowability condition by 12 to 25%,
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,

Dosage

Depending on the required strength and workability and ambient temperature, use BC21 up to 1 to 2% of cement weight.

Instruction of use

To achieve the optimal result, after mixing ingredients add BC21 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.
BC21 is compatible with all kind of Portland cement,
Never add the product to dry materials.
