HUMIDITY-CONTROLLING BUILDING MATERIAL AND METHOD FOR PRODUCING SAME

WIPO Patent Application WO/2011/052291

A1

Disclosed is a humidity-controlling building material which is obtained by subjecting a shaped article to autoclave curing, said shaped article being obtained by dehydration-pressing a kneaded product of water and a hydraulic composition that contains an autoclaved lightweight cellular concrete powder and cement. The humidity-controlling building material has a volume of pores having a diameter of not less than 0.1 μm of 0.1-0.25 cc/g, and a pore volume as obtained by subtracting the volume of pores having a diameter of not less than 0.1 μm from the total pore volume of 0.2-0.5 cc/g. The humidity-controlling building material is significantly improved with respect to both strength and humidity absorption/desorption performance.
