Abstract

249,899. Novocrete & Cement Products Co., Ltd., and Burney, C. D. Oct. 25, 1924. Plastic compositions containing fibres and cement &c.-Fibrous materials such as sawdust, shavings, coir, cork, wood waste, sizal, paper pulp, &c. are mixed, before and after moistening, with a dry hygroscopic substance which acts exothermally when brought into contact with moisture, and while heat is still being evolved the mixture is added to cement, concrete, &c. and cast in moulds. The dry hygroscopic substance may, for example, be dry caustic soda, quicklime, or magnesium chloride. The fibrous material may be subjected to a preliminary treatment to reduce its tendency to change in volume with change of moisture content, such as washing with a weak solution of alkali or acid. It may also undergo a preliminary impregnation with any suitable solution, followed if desired by treatment with a precipitating agent, or the dry hygroscopic substance may itself act as the precipitating agent. For example, sawdust may be impregnated with ferric chloride solution and then mixed with flaked caustic soda; cement and water are then added while heat is still being evolved, and the mixture is moulded under pressure as described in Specification 244,178. Specifications 236,450, 252,906, and 253,007 are referred to.
