Summary:PROBLEM TO BE SOLVED: To prevent ammonia gas generated from a mortar- or concrete-based material from mixing into a clean space such as a clean room, or a gathering room or a display room of artistic works and to prevent the contamination of clean air by the gas. SOLUTION: The mortar- or concrete-based material is used in a building in which the clean space exists. The mortar- or concrete-based material for clean space is obtained by blending an ammonia-decomposing agent or an ammonia-absorbing agent such as a hypochlorite, phosphoric acid or the like into the material when the material is kneaded.
