The production process of reinforced fiber cement board and fiber reinforced calcium silicate board is basically the same, but the raw materials used are different. Due to the different materials, the hardening reaction mechanism is also different, and the products are also different. Different manufacturing processes have different requirements for raw materials. For example, natural curing and autoclaved curing have obvious differences in the selection of cementitious materials. Natural curing products must use cement as the main cementing material, its hardening reaction is the use of cement hydration reaction to produce strength, generally use room temperature water retention hardening or steam accelerated hardening for several hours and then turn to room temperature water retention hardening. Autoclonic curing products can use cement hydration to produce strength, plus quartz powder, under high temperature and high pressure and cement hydration produced by calcium oxide chemical reaction to produce strength; Hardening can also be achieved by a hydrothermal synthesis reaction of saturated steam using lime and quartz as the main base materials.

For natural conservation products, the cementing materials are mainly cement with different labels, and can also include a small amount of ultra-fine quartz, whose reaction products are mainly calcium silicate hydration; For autogenous curing products, cementing materials include calcium oxide or Ca(OH): and silica. These calcium materials and silica materials together constitute calcium silicate cementing, and the reaction products are mainly tobermulite. That is to say, cement is a kind of calcium silicate cementitious material including calcium material and silica material, which itself has a cementitious effect and hardening into cement stone, while calcium oxide and Ca(OH); Only the calcium material, must be combined with silica as silica material, under a certain pressure of saturated steam hydrothermal synthesis reaction to generate cementing material.
