Abstract

PURPOSE: To obtain light, non-flammable construction materials which are excellent is sound absorbing and heat insulating capability and which is useful as ceilings and wall finishing materials, by subjecting a mixture of waste liquor left over in the production of pulp and calcined gypsum to press work, whereby industrial waste can be effectively utilized.
CONSTITUTION: Waste liquor left over in the production of pulp is condensed to obtain paste having water content of 80%. This paste is mixed with 40W100% by weight, based on the weight of solid in the paste, of calcined gypsum. An admixture of an extending agent, a reinforcing agent, a bonding agent, a coloring agent and a deodorant is mixed as neccessary with the mixture obtained in the above-mentioned step. The resulting mass is shaped by a molding press. The molded product thus obtained is forcibly dried at a temperature of not more than 100°C or naturally dried such that the water content is reduced to around 10%, to obtain a final product.
