PURPOSE:To develop an inhi bitor which can effectively prevent fly ash formed when coal is burnt from being hardened with water and can suppress the heat generation caused thereby. CONSTITUTION:The inhibitor comprises a polymer containing 10-100mol% monomer containing a carboxyl or carboxyl anhydride group or its salt. It can reduce the strength of a product formed by the hardening of fly ash by the pozzolanic reaction, can suppress the heat generation caused thereby, and can improve the handleability of fly ash. |
