Abstract
A method for sheet forming a remarkably waterproof gypsum hardened body, in which a main component consisting of gypsum dihydrate, slag and calcium hydroxide and additives are added with a part of the main component coated with a hydrophobic diorganopolysiloxane fluid having a kinetic viscosity of 10-10,000 CS at 25.degree. to be sheet formed and cured. The hydrophobic diorganopolysiloxane fluid is uniformly dispersed through the sheet formed gypsum hardened body and its strong water repelling property makes the gypsum hardened body remarkably waterproof to be used suitably as both interior and outdoor construction materials.
