METHOD OF REFILLING WITH WASTE SLURRY AND SELF-CURING SLURRY USED THEREFOR

摘要

PURPOSE: To develop a method of utilizing a waste slurry which is very hard to utilize and is produced in a large quantity during excavation in recent years and to simply produce an excellent refilling material from a waste slurry. ;CONSTITUTION: In a process for refilling a prescribed place by adding a cement- based solidifying material to a waste slurry, transferring the mixture (self- solidifying) to the place and laying it in the place, a curing retardant is further added to the mixture. It is desirable that the mixture still further contains a dispersant. The mixture does not solidify but flowable for a definite time necessary to transfer it to the place to be refilled and can develop sufficient strengths after being layed in the place.;COPYRIGHT: (C)1995,JPO
