<p><P>PROBLEM TO BE SOLVED: To provide a method for easily processing waste concrete at a low cost without using high-temperature calcination or the like. <P>SOLUTION: A water-contained pulverized waste concrete having a water content of 5-16 wt.%, an unsaturated polyester resin, a hardener, and a hardening accelerator are mixed, and the obtained mixture is charged into a specified shaping mold and hardened at an ordinary temperature to give a resin concrete product. Preferably, the water-contained pulverized waste concrete is mixed at a ratio of 50-90 wt.% vs. the total of the unhardened mixture. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
