Description

BC20 is used to increase concrete workability and slump, and reduce the ratio of water to cement under constant flowability condition for obtaining concrete with higher finial strength.

 Producing mortar or concrete with a controlled level of expansion,
Producing mortar for steel base preparation and filling joints, voids, and connecting anchor rods, precast members, steel and concrete pipes,
Injection operations in dams, tunnels and alluvial and stone shearing,
Concrete repair work that requires preventing shrinkage of substitute concrete.

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

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

Color: brown
Physical state: Liquid
Density: 1.05 g/cm3
PH: Approx. 7
Solubility: In water
Chloride: Nill

Storage: in capped container protected against air and frost
Shelf life: 1 year in original package
Packaging: in 20 and 220 kg containers

 The ambient temperature for use should be 5 to 30° C,
The exact dosage rate may be obtained by trial mixes
The more the cement percentage, the less the
consumption of Grout Admixture,
Depending on the ambient temperature, the maximum
expansion level will be attained 1 to 2.5 hours after mixing
concrete in cement,
BC2 is compatible with Portland Cement,
When simultaneous use of several admixtures in
concrete mix is required, consult Research Center of Beton
