Investigation of mechanical properties of fiber-cement board reinforced with cellulosic fibers

[摘要] The article presents experimental research on the development of the optimal composition of cement-fibrous composite material for the manufacture of autoclaved fiber-cement boards with high physical, mechanical and economic parameters. The effect of the cement-sand ratio of the matrix, the specific surface area of the sand and the cellulosic fibers content on the physical and technical properties of the material is shown. It is established that the optimum cement-sand ratio of the matrix associated with a specific surface area of quartz sand 310 m2/kg is 1:2. The optimal content of cellulosic fibers according to the criterion of increasing the strength is 5-7.5%.
