Ash made of amorphous silica is a type of material that is used as an additive in cement. It is produced by burning rice husks, which are a waste product of the rice milling process. The ash that is produced is high in amorphous silica, which makes it an ideal material for use in cement. When used as an additive in cement, ash made of amorphous silica can improve the strength and durability of the resulting concrete. This is because the amorphous silica in the ash reacts with the calcium hydroxide in the cement to form additional calcium silicate hydrate (C-S-H) gel. This gel fills in the pores and voids in the concrete, making it more dense and less permeable to water and other substances. In addition to improving the strength and durability of concrete, ash made of amorphous silica can also reduce the environmental impact of cement production. This is because it is made from a waste product that would otherwise be discarded, and because it reduces the amount of cement that is needed to achieve a given strength and durability. Overall, ash made of amorphous silica is a valuable additive for use in cement. It improves the strength and durability of concrete, reduces the environmental impact of cement production, and is made from a waste product that would otherwise be discarded.
