Calcium-silicate passive fire protection board being clad around steel structure in order to achieve a fire-resistance rating. Calcium silicate is commonly used as a safe alternative to asbestos for high-temperature insulation materials. Industrial-grade piping and equipment insulation is often fabricated from calcium silicate.

Thaumasite is a calcium silicate mineral, containing Si atoms in unusual octahedral configuration, with chemical formula Ca 3 Si(OH) 6 (C O 3)(SO 4)·12H 2 O, also sometimes more simply written as CaSiO 3 ·CaCO 3 ·CaSO 4 ·15H 2 O. It occurs as colorless to white prismatic hexagonal crystals, typically as acicular radiating groups. It also ...

Natural pozzolana (volcanic ash) deposits situated in Southern California in the United States. Pozzolans are a broad class of siliceous and aluminous materials which, in themselves, possess little or no cementitious value but which will, in finely divided form and in the presence of water, react chemically with calcium hydroxide (Ca(OH) 2) at ordinary temperature to form compounds possessing ...
It has better pulpotomy outcomes than calcium hydroxide or formocresol, and may be the best known material, as of 2018 data. [1] For pulp capping, it has a success rate higher than calcium hydroxide, and indistinguishable from Biodentin. [2] MTA, when mixed with water, forms a calcium silicate hydrate gel which contains calcium hydroxide.
Cement hydration and strength development mainly depend on two silicate phases: tricalcium silicate (C 3 S) , and dicalcium silicate (C 2 S) . [1] Upon hydration, the main reaction products are calcium silicate hydrates (C-S-H) and calcium hydroxide Ca(OH) 2, written as CH in the cement chemist notation. C-S-H is the phase playing the role of ...
Tacharanite is a calcium aluminium silicate hydrate (C-A-S-H) mineral of general chemical formula Ca 12 Al 2 Si 18 O 33 (OH) 36 with some resemblance to the calcium silicate hydrate (C-S-H) mineral tobermorite. It is often found in mineral assemblage with zeolites and other hydrated calcium silicates.
