摘要
PROBLEM TO BE SOLVED: To provide a microsilica having fluidity capable of being easily added to a fibrous cement mixture and reducing its transportation and storage cost by using the micro silica having a bulk density within a specific range.;SOLUTION: In this method for producing a cement roofing and a wall cladding containing no asbestos and containing a fibrous material, a mixture consisting of one or more kinds of volcanic ash materials containing cement, water, the fibrous material containing no asbestos and the micro silica is molded and hardened into a roofing and wall cladding product. In this case, the micro silica to be added into the mixture has a bulk density of from 425 kg/m3 to 550 kg/m3.;COPYRIGHT: (C)2001,JPO
