MOISTURE CONDITIONING BUILDING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method of producing a moisture conditioning building material, capable of producing the moisture conditioning building material more excellent in absorption and desorption performance than a conventional moisture conditioning building material.SOLUTION: A method of manufacturing a moisture conditioning building material includes a first calcination step (S11) of calcining aluminum hydroxide to produce an activated alumina, a kneading step (S12) of mixing a mixture of the activated alumina, clay and an additive with water and then kneading the resultant mixture, and a second calcination step (S15) of molding the mixture raw material kneaded in the kneading step (S12) in a predetermined shape and then calcining it.
