2 results about "Alite" patented technology

Alite is an impure form of tricalcium silicate, Ca₃SiO₅, sometimes formulated as 3CaO·SiO₂ (C₃S in cement chemist notation, CCN) with typically 3-4% of substituent oxides. It is the major, and characteristic, mineral phase in Portland cement. The name was given by Törnebohm in 1897 to a crystal identified in microscopic investigation of Portland cement. Alite is a name in common use in the cement industry, but it is very rare in nature (known as hatrurite).
