Abstract
The problems to be solved by the invention are to provide a fiber reinforced cement composition for obtaining a fiber reinforced cement product which is excellent in bending strength, dimensional stability and installation property such as handling property, flexibility performance and nail performance, as well as a process for manufacturing the product. Namely, the fiber reinforced cement composition comprises the following raw materials: a hydraulic inorganic material, a siliceous material and a woody reinforcement, wherein the siliceous material is a mixture of an average particle size of not less than 15 .mu.m and not more than 50 .mu.m which is burned ash of coal and/or rhyolite and an average particle size of not less than 1 .mu.m and not more than 15 .mu.m which is burned ash of coal and/or rhyolite. The effects of the present invention, it is possible to obtain a fiber reinforced cement product having good bending strength, dimensional stability and installation property such as handling property, flexibility performance and nail performance.
