FLUIDIZATION TREATMENT SOIL OF COAL ASH EFFECTIVE UTILIZATION AND UTILIZATION METHOD OF THE FLUIDITY TREATMENT SOIL

摘要

PROBLEM TO BE SOLVED: To provide fluidization treatment soil in which effective utilization of coal ash is contrived and the characteristics of coal ash can be fully displayed. ;SOLUTION: With regard to the fluidization treatment soil of coal ash effective utilization, coal ash is utilized as reinforcing composition, improved soil or raw material of processed soil. Or the characteristics having coal ash, for instance, the characteristics indicating fluidity, strength or material separation resistance are utilized as the framework of a ground reinforcing and ground improvement method. In the case, with regard to the constitution, soil and water, a solidifier and coal ash are stirred and mixed, fluidity and strength of coal ash is displayed, and physical property increasing material separation resistance by mixing with muddy water is prepared.;COPYRIGHT: (C)1998,JPO
