<p><P>PROBLEM TO BE SOLVED: To provide a granule containing versatile charcoal in which the carbonized material is hardly reduced to powder, the used-up granule is readily reproduced causing no littering, and which scarcely brings about lowering of strength unlikely as conventional products not only when used solely, as a matter of course, but also when incorporated in a concrete product or mortar product, and to provide a method for producing the same. <P>SOLUTION: The granule containing versatile charcoal is produced by charging a carbonized material, aggregate and cement into a rotary drum for granulation, adding water containing a flocculant little by little while rotating the rotary drum and hardening the mixture. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
