解説オルトケイ酸カルシウム：Ca2SiO4(172.24)．セメントクリンカーの10～40％ を占める主成分の一つで，セメント業界ではケイ酸二石灰(belite)とよばれる．独立した四面体型構造のSiO4からなる．
一般的な説明Dicalcium silicate occurs when cement clinker is not completely saturated with calcium oxide. Pure dicalcium silicate melts congruently at 2130 ℃. In lime-rich raw mixes, C2S forms already at temperatures below 1000 ℃ by solid-state reaction. During the sintering process in the presence of a melt above 1250 ℃, C2S incorporates additional Ca2+, resulting in the formation of C3S.
