Abstract
The invention relates to a hardened calcium silicate material characterized by having Ib/Ia which is greater than 3 (wherein Ib represents the diffraction peak intensity of the tobermorite (220) plane in powdery X-ray diffractometry; and Ia represents the minimum diffraction intensity in the angle region located between two diffraction peaks in the tobermorite (220) and (222) planes;), having a specific gravity of 0.2 or more but less than 0.7, and being substantially free from bubbles having a maximum diameter exceeding 200 &mgr;m; and a process for producing the same.
