PURPOSE:To obtain a calciumsilicate molded body which has a light weight and also a practical flexural strength. CONSTITUTION:This calciumsilicate molded body is constituted of a structure wherein nearly spherical secondary particles formed by three-dimensionally Tobermorite crystals or a small quantity of other calciumsilicate crystals with them, are mutually connected, and the spherical secondary particles have 10-120mum of the outer diameter before the molding and whose hollow rate and the free sedimentation molded body density are <=30% and <=0.12g/cm<3>, respectively. |
