Fiber reinforced calcium silicate board is made of silicon material and calcium material mixed, calcium material and silica material in the substrate after autoclave curing, under the action of saturated steam about 1MPa hydrothermal synthesis reaction to produce strength, its internal cavity is more. Density is relatively small, compared with fiber cement board, has lower thermal conductivity, lower shrinkage rate, but also has excellent fire performance, in the open fire will not occur cracking and combustion, do not produce smoke and toxic gas. However, because the density of calcium silicate board is slightly smaller than that of fiber cement board, the product strength is lower than that of fiber cement board.
