<P>PROBLEM TO BE SOLVED: To manufacture a cement formed body having a good compression resistive strength by a small amount of water. <P>SOLUTION: The cement formed body is manufactured by kneading a cement, a microparticle having a particle diameter of ≤1 mm and water of 5 to 20% to the cement, and thereafter compression forming the kneaded material. Particularly, the microparticle is utilized which is prepared by water granulating municipal waste melt slag and sieving and sorting the granulated slag. Thus, a cement and a microparticle are compression formed, so that a cement formed body is well manufactured; water is added in a ratio of the water content necessary and enough to the cement of 5 to 20%, so that the use amount of water becomes smaller than in conventional cement forming and the curing time can e largely reduced and occurrence of slippage in compression is prevented to well carry out the forming; further, as the microparticles becoming aggregates, microparticles having a particle diameter of ≤1 mm are sieved and sorted and used, so that the compression-resistive strength can be increased. <P>COPYRIGHT: (C)2012,JPO&INPIT |
