Zusammenfassung:PROBLEM TO BE SOLVED: To obtain a material which can endure superlow temp. and prevents freezing, and is incombustible and has higher strength and durability by incorporating a specified foamed aggregate into a cement compsn. SOLUTION: A waste glass is pulverized, classified and foamed by heating to obtain a glass foamed body having 0.3 to 5.0mm particle size. A powder of a crystalline ceramic material selected from aluminate compds. and silicate compds. is adhered and fused on the surface of the glass foamed material to obtain a foamed aggregate. The obtd. foamed aggregate is compounded in a cement in (5 to 6):1 mixing ratio of the aggregate to the cement compsn.
