The SILICA CEMENT ADMIXTURE is generally the volcanic ash that can generally be understood as the cement supplement. With characteristics such as water-proofing, neutralizing alkali, providing strength, avoiding efflorescence, it is an indispensable product in a country like Nepal where the alkalinity of cement is very high. Marron Trading rapidly became popular amongst quality-driven consultants with the ever-increasing market of SILICA. Marron Trading is often understood and called as “SILICA” in the Nepali Engineering fraternity.
Silica Cement Admixture is made from Natural Volcanic ore. lt is natural amorphous mineral and is processed in controlled environment thus achieving equal grain size and quality in overall. As Silica Cement Admixture is in a finely divided state it combines with calcium hydroxide (produced by the hydrating Portland cement) in the presence of water to form stable calcium silicates, which have cementitious properties. This reaction is termed as pozzolanic reaction. Dense and durable concrete can be produced by the addition of Silica Cement Admixture. This is achieved because the presence of reactive silica generally reduces the heat of hydration and thus helps reducing the adverse effect of rapid hydration reaction resulting from the use of rich mixtures. In addition to this both grain and pore refinements occurred due to the reactive silica, resulting in increased resistance to permeability of water, carbon dioxide and other aggressive agents (acids), it also improves resistance to attack by sulfate soils and by sea water, and reduce bleeding.
Japan is a country which experiences frequent strong earthquakes and concrete strength is one of the most important factors for designing and constructing high-rise buildings and other civil infrastructures. Compressive strength of 100 MPA which is standard concrete strength for 60 storey buildings in Japan, can be achieved by adding suitable amount of Silica Cement Admixture.
Advantages of using Silica Cement Admixture:
• It improves the strength of concrete.
• It improves the permeability hence concrete becomes more water resistant therefore acts as water proofing material.
• Improves durability against salt water, acids and aggressive agents.
• Prevents Efflorescence.
• It decreases the heat of hydration.
• It improves freezing and thawing action of concrete.
• Resists Segregation.
• Creates siliceous gel layer on the particle surface for the architectural finish.
• It improves self-healing effects of hair cracks.
• Improves workability.
• Produces quality concrete surface that looks beautiful, smooth and attractive.
• It is an inorganic product with reactive silica content of above 86%.
• It has longest storage date.
• It improves the design strength intensity by 40% and more.
• It prevents the separation of the aggregates and the water at the time of casing.
• It helps keep the smooth ess and beauty of the finished concrete almost
