Volsil Silica is a Cement Admixture powder made from Natural Volcanic Ash. It is a natural amorphous material and processed in a well controlled factory, its quality and grain size is very fine. VolsilSilica is the best Cement Admixture for long-lasting concrete constructions.
Volsil Silica Cement Admixture powder is formed during volcanic eruptions. Volcanic glass is relatively high in silica, and its physical and chemical properties could be referenced with ASTM C618-93, a Standard Specification Natural Pozzolan for Use as a Mineral Admixture in Portland Cement Concrete’.
This paper presents comprehensive details of the physical, chemical properties of volcanic ash, and its micro-structure and hydration products. It also covers effect of volcanic ash on consistency, setting times, workability, compressive strength, electrical resistivity of cement and concrete
Volsil is also recommended for painted concrete since it keeps the original color of the concrete for years and prevents the painted concrete from partial discoloration. Volsil protects concrete against deterioration and alkali-aggregate reaction by pozzolanic reaction. Concrete with Silica (Above 92% and more SIO2) gets stronger in years through its pozzolanic reaction.
Volsil Silica is a Cement Admixture improve the strength, durability and workability of concrete.
