PURPOSE:To obtain cement composition wherein extrusion molding is easy and a produced, cured and molded body is excellent in strength and harmful asbestos is not contained by allowing cement, fibrous wollastonite, a spherical particle-base inorganic aggregate, reinforcing fiber and a cellulose-base admixture to be incorporated. CONSTITUTION:This cement composition consists of composition incorporating cement, fibrous wollastonite, an inorganic aggregate mainly consisting of spherical particles reinforcing fiber and a cellulose-base admixture. In case of using this composition, a cement molded body which has high strength and is excellent in shock resistance is obtained by extrusion molding with good moldability at high efficiency. Such cement molded body is preferably used, e.g., as the floor material such as a deck material and a corridor material of multiple dwelling houses. Furthermore, harzard of carcinogenesis due to waste dust of asbestos is eliminated even in a producing process and even at a time of use because asbestos is not contained. |
