Abstract

1. A process for the production of fire proof light-weight plates true to size having a gross density of from about 160 kg/m**3 to 800 kg/m**3 on the basis of fibrereinforced calcium silicate compositions by reacting amorphous and crystalline silicium dioxide or materials containing these, respectively, with calcium oxide or materials containing this, respectively, in a molar ratio of CaO to SiO2 of 0.8:1 to 1.1:1 with adding synthetic calcium silicate and incorporating toxicologically unobjectionable fibre materials in the presence of water and by shaping carried out with dewatering and autoclave indurating, characterized in that one add to the CaO-SiO2 starting mixture a synthetically prepared calcium silicate granulate or powder, respectively, having a molar ratio of CaO to SiO2 of 0.8:1 to 1.1:1 and one carries out the reaction for th slow development of the gel structure before the shaping (pre-reaction) without external application of heat in a minimum time being in an inverse function relationship to the desired gross density of the light-weight plates to be produced of at least 5 hours in case of the production of light-weight plates having a gross density of 800 kg/m**3 increasing to at least 12 hours in case of the production of light-weight plates having a gross density of 160 kg/m**3.
