BP EXPANDABLE SLUDGE COMPOSITION FOR FILLING CAVITIES USING PB BYPRODUCT

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an expanded sludge composition for filling a subterranean hollow portion such as a sink hole, a tunnel back surface and a pulverized sludge well by a grouting method. More particularly, the present invention relates to an expanded sludge composition comprising BP byproduct, paper ash and hydraulic inorganic binder, Self-leveling performance is developed to fill cavity space. In the curing process, BP byproduct and paper ash react with each other to expand and cure while foaming. The present invention relates to an inflated sludge composition for filling a cavity using a byproduct of BP which causes an inflated pressure of an appropriate amount to be filled tightly.
