Abstract

PURPOSE:To contrive to improve strength, freeze resistance and extrusion molding properties in producing a cement lightweight molded article containing foamed particles of thermoplastic synthetic polymer, reinforcing fibers and an improver for plasticity, by using specific fibers as the reinforcing fibers. CONSTITUTION:(A) Portland cement is blended with (B) an inorganic filler (e.g. talc), (C) reinforcing fibers consisting of polypropylene short fibers subjected to crimping processing and wood pulp, (D) an improver (e.g. methyl cellulose) for plasticity, (E) foamed particles of thermoplastic synthetic polymer (expanded polystyrene particles) and (F) water. Then the prepared plastic mixture is extrusion molded, aged in an autoclave and set to give a cement lightweight molded article. Short fibers having 5-20mm length are preferable as the short fibers and the amount of the short fibers added is properly about 0.2-1.5wt.%.
