Silica Cement Admixture – Volsil

Volsil Silica Cement Admixture is a pozzolanic material containing A-Sio2 amorphous silica and trace amounts of residual minerals.

The concrete specimens containing 5%, 10%, 15%, and 20% A-Sio2 replacement by weight for cement had the best compressive and flexural strength, and the replacement of cement separately and in combination with a super plasticizing admixture could be used to improve the mechanical properties of conventional Concrete Admixture Additives.

Volsil Silica Cement Admixture is a pozzolanic material containing A-Sio2 amorphous silica and trace amounts of residual minerals.

The concrete specimens containing 5%, 10%, 15%, and 20% A-Sio2 replacement by weight for cement had the best compressive and flexural strength, and the replacement of cement separately and in combination with a super plasticizing admixture could be used to improve the mechanical properties of conventional Concrete Admixture Additives.

Due to its high pozzolanic activity, fine-grained amorphous silica (a-SiO2) is a valuable addition to blended binders used in the manufacture of concrete. The source of A-SiO2, which is used in cement-based composites, is extremely varied. Quite a few supplementary cementing materials (SCMs), which are used to partially replace Portland cement, contain SiO2 in amorphous form in varying amounts. In this study, it is looked into whether commercially available silica powder can be used in cement paste mix designs in place of Portland cement. The reference binder is Portland cement CEM I 42.5R made in accordance with EU standards. By the mass of cement, silica is added in dosages of 5, 10, 15, and 20%. All of the pastes under study maintain a constant water-to-binder ratio. Specific surface area, density, loss on ignition, pozzolanic activity, chemical composition, and the percentage of SiO2 in the amorphous phase for the applied silica. Basic physical characteristics like bulk density, matrix density, and total open porosity are accessed for the pastes developed on the basis of a cement-silica blended binder. MIP analysis is used to determine the distribution of pore sizes. The automatic Vicat apparatus measures the first and last times that fresh mixtures are set. Utilizing compressive strength, bending strength, and mechanical resistivity to determine the impact of silica cement admixture. The automatic Vicat apparatus measures the first and last times that fresh mixtures are set. Using compressive strength, bending strength, and dynamic Young’s modulus measurements, we can determine the impact of silica cement admixture on mechanical resistivity. The collected data shows that paste mixtures containing silica are workable, while the setting process is sped up. Conversely, cement pastes containing a-SiO2 experience a slight decrease in porosity and an improvement in mechanical resistivity as a result of silica’s reaction activity with Portland cement minerals.

Complementary cementitious materials (SCMs) are now frequently used to create cement composites, either by blending different types of cement or by adding them separately to the composite mixture. Utilizing active silica-rich materials is a suitable replacement for some of the Portland cement [1]. Additionally, since the majority of SCMs are industrial by-products, using them in cement-based composites is advantageous for both the environment and the economy. In both the fresh and hardened states, the admixture of various SCMs typically modifies the properties of cement composite to some extent. Different chemical and mineralogical compositions, as well as different particle size characteristics that are related to water requirement and reactivity, all influence these changes [2]. Due to their size difference, active silica particles fill the spaces between cement and other component particles. The formation of a denser microstructure is aided by the filler effect because the hydration products minimise and bridge the gaps between the particles.

Delivery in India: The best products are delivered to customers by Guru Corporation, which also offers the best transportation services. Our plant manager examines every item that is about to be shipped to ensure proper manufacture and packing. Due to a large number of orders, materials frequently experience a few-day delay. If there is a significant delay in the dispatch of your order, we will contact you by phone or email.

Delivery Outside India: For export shipments, we use the best transportation network on a basic FOB, CNF, or CIF basis. Because of the container imbalance, which makes it difficult for the trade to get equipment space on vessels, the specified stuffing day and vessel plan are only indicative and subject to change without prior notice in light of volume gathering, equipment, and space accessibility.
