Document Type and Number:
Japanese Patent JP4632507
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a latent heat storage cement-based building material which exhibits very small dimension change before and after the phase transition temperature. SOLUTION: This building material is obtained by incorporating a micro- encapsulated latent heat storage material having a volume average particle size of >=0.5 and <=50 μm and mixing >=50 and <=500 pts.wt. of a porous calcium silicate powder to 100 pts.wt. of cement, and then forming and curing.
