Gray Silica Fume offered by our company, is an amorphous polymorph of silicon dioxide, silica. This silica is an excellent admixture for concrete as it leads to better engineering properties. It reduces thermal cracking, improves durability, and increases strength. It is produced by some chemical processing of the ash. Gray Silica Fume provides a more uniform distribution and a greater volume of hydration products. This fume can be easily purchased by our clients at cheaper rates, as per their requirements.
