Humidity-controlling building material and method for producing same

Abstract

A humidity-controlling building material, which is produced by subjecting a molded product obtained by dehydration pressing a kneaded product of a hydraulic composition comprising an autoclaved lightweight aerated concrete powder and cement, and water; to autoclave curing, wherein a volume of pores with a diameter of 0.1 μm or more is 0.1 to 0.25 cc/g and a pore volume resulting from subtracting a volume of pores with a diameter of 0.1 μm or more from a total pore volume is 0.2 to 0.5 cc/g exhibits remarkably excellent performance in terms of both strength and moisture absorption and desorption performance.
