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.

 Reducing shrinkage, cracking and bleeding of concrete and mortar,
Accelerating the final finishing operation and preparation of the mortar and concrete surface,
Increasing compressive, tensile, bending and shear strength
Providing a volume expansion of up to 2% in concrete or mortar,
Reducing steel corrosion,
Increasing the concrete setting,
Compatible with different types of Portland Cement,
Suitable for connecting concrete and steel surfaces such as protecting post-stressed cables and Preparation heavy machinery bases

a) Mortar
When sand-cement ratio is 1 or less than 1, the dosage rate will be 0.5% of cement weight,
When sand-cement ratio is more than 1, the dosage rate will be 1% of cement weight,
b) Concrete
For concrete mixes with different cement percentage, the dosage rate will be 0.5% to 1% of cement weight

Add the required quantity of BC2 to mortar or concrete ingredients, then mix for 3 to 5 minutes. To achieve the predetermined controlled expansion, use the mortar or concrete within 20 minutes
