Kind Code:
A1
Abstract:
[Problem] To provide a powdered tobermorite type calcium silicate-based material that can exhibit high oil absorption. [Solution] A powdered tobermorite type calcium silicate-based material characterized in that (1) a SiO2/CaO molar ratio is 1.5 or more, and (2) a cumulative volume of pores of pore sizes of 3.6 to 200 nm is 0.9 cc/g or more and a cumulative volume of pores of pore sizes of 3.6 to 5000 nm is 2.6 cc/g or more.
