These are tricalcium silicate (3CaO.SiO2), aluminate (3CaO.Al2O3) and a ferrite phase from the (2CaO.Fe2O3 - 6CaO.2Al2O3.Fe2O3) solid solution series that at one time was considered to have the fixed ...

It is the hydration of the calcium silicate, aluminate, and aluminoferrite minerals that causes the hardening, or setting, of cement Materials used above 1 billion tons/year carbon 8.6 billion ...

Current techniques for fending off sulfates include cement mixtures low in tricalcium aluminate and with a low water-to-cement ratio, because it makes for a less reactive and less porous concrete.
