Our Brand Volsil - Silica Cement Admixture contain more then 92 % of amorphase silicon dioxide and high surphase area...
Volsil A-Sio2 is a pozzolanic material containing A-Sio2 amorphous silica and minor amounts of residual minerals
Test results indicated that the concrete specimens containing 5%, 10 %, 15 %, 20% A-Sio2 replacement by weight for cement had the best compressive and flexural strength and the replacement of cement separately and together using a super plasticizing admixture could be utilized to improve the mechanical properties of the conventional concrete mixtures.
Amorphous silica (a-SiO2) in fine-grained form possesses a high pozzolanic activity which makes it a valuable component of blended binders in concrete production. The origin of A-SiO2 applied in cement-based composites is very diverse. SiO2 in amorphous form is present in various amounts in quite a few supplementary cementing materials (SCMs) being used as partial replacement of Portland cement. In this work, the applicability of a commercially produced silica powder as a partial replacement of Portland cement in cement paste mix design is investigated. Portland cement CEM I 42.5R produced according to the EU standard is used as a reference binder. silica is applied in dosages of 5 and 10, 15, 20 % by mass of cement. The water/binder ratio is kept constant in all the studied pastes. For the applied silica, specific surface area, density, loss on ignition, pozzolanic activity, chemical composition, and SiO2 amorphous phase content. For the developed pastes on the basis of cement-silica blended binder, basic physical properties as bulk density, matrix density, and total open porosity are accessed. Pore size distribution is determined using MIP analysis. Initial and final setting times of fresh mixtures are measured by the automatic Vicat apparatus. Effect of silica cement admixture on mechanical resistivity using compressive strength, bending strength, and dynamic Young''''s modulus measurement. The obtained data gives evidence of the workability of paste mixtures with silica, whereas the setting process is accelerated. On the other hand, the reaction activity of silica with Portland cement minerals results in a slight decrease of porosity and improvement of mechanical resistivity of cement pastes containing a-SiO2.

Pozzolan cement is a blend of Portland cement and pozzolanic materials, such as fly ash or silica fume. It enhances concrete properties by improving workability, durability, and reducing heat of hydration. Pozzolan cement offers sustainable construction solutions and reduces the environmental impact of concrete production.
Type 2 OPC cement, a variant of Portland cement, possesses moderate heat of hydration and sulphate resistance. Its balanced properties make it suitable for general construction applications, providing durable and stable structures in environments with moderate sulphate exposure. Pozzolan cement is a blend of Portland cement and pozzolanic materials, such as fly ash or silica fume. It enhances concrete properties by improving workability, durability, and reducing heat of hydration. Pozzolan cement offers sustainable construction solutions and reduces the environmental impact of concrete production. Clinker Cement clinker is the intermediate product produced during the cement manufacturing process. It consists of finely ground materials, such as limestone, clay, iron ore, and shale, heated to high temperatures in a kiln. Clinker forms the basis of various types of cement when combined with gypsum and other additives.

Microsilica (silica fume) is a by-product from silicon metal or ferrosilicon industries, is an amorphous silicon dioxide SiO2. This product reacts chemically with the calcium hydroxide in the cement paste which yields a calcium silicate hydrate gel that significantly enhances strength and durability. The super fine microsilica fills the voids between cement particles creating a very dense, less permeable concrete. White Cement advantages: Sustainability: Solar Reflectance Index (SRI): Floors finished with white or pastel color concrete will have a much higher SRI than floors with gray concrete, therefore they will reflect light better, and generate energy savings for the lifetime of the floors. Reduction of Heat Island effect: By constructing buildings with white concrete roofs or light-colored roof tiles, the Heat Island Effect is reduced from surfaces generating less heat and improved reflectivity. Architectural Concrete: White Portland Cement is ideal for decorative concrete and Architectural Concrete applications, Masonry and Cementitious Building Products. A key advantage of using white cement for these applications is that it provides a base color that can be tinted to custom colors to meet any color spectrum demand.
