MIXED COMPOSITION OF RECLAIMED COAL ASH

摘要

PURPOSE: A reclaimed coal ash mixture composition is provided to increase permeation coefficient and compression speed of a mixture when mixed with spoils, to shorten time and cost for improving reclaimed ground, and to minimize environmental contamination. CONSTITUTION: A reclaimed coal ash mixture composition is obtained by adding 0.01~5 weight% additives for accelerating crosslinking action for coherence and flock formation to 100 weight% reclaimed coal ash, wherein the reclaimed coal ash is directly used without separate separation and selection process. The additive is at least one selected from a coagulant, coagulant aid, and flocculation aid. The coagulant is any one selected from metal salt, polyaluminum chloride, aluminum sulfate and iron salt.
