METHOD FOR SELECTIVELY INHIBITING SULFATE-REDUCING BACTERIUM, GYPSUM COMPOSITION CAPABLE OF INHIBITING PROLIFERATION OF SULFATE-REDUCING BACTERIUM BY SAID METHOD, GYPSUM-TYPE SOLIDIFYING MATERIAL, AND GYPSUM-TYPE BUILDING MATERIAL

摘要

A method for performing selective bacteriostasis of a sulfate-reducing bacterium, the method selectively inhibiting proliferation of the sulfate-reducing bacterium by allowing chelated Al to coexist in an environment where the sulfate-reducing bacterium exists, and a gypsum composition containing calcined gypsum (A) and chelated Al (B), in which the chelated Al (B) is contained in a range of 0.01 to 20 mass parts relative to 100 mass parts of the calcined gypsum (A).
