Document Type and Number:
Japanese Patent JP2890389
Kind Code:
B2
Abstract:
PURPOSE:To rapidly mass-produce a filler having prescribed strength At a low cost by adding hydraulic cement and coal ash to soil and sand contg. a prescribed amount of water such as a waste slurry, soft surplus soil, etc., then molding the resulting mixture into a desirable size and thereafter hardening the moldings. CONSTITUTION:Hydraulic cement and coal ash are added to soil and sand contg. a prescribed amount of water such as a waste slurry, soft surplus soil, etc. The amounts to be added of the hydraulic cement and the coal ash depend on the water content of the soil and sand. Then the resulting mixture is molded into a prescribed size to produce moldings and thereafter the moldings are hardened to produce the objective filler. Thus the filler having narrower variation in dimension can be mass-produced in a very short time and also at a low cost owing to the utilization of the waste slurry, etc. The filler thus produced can appropriately be used as a material for the back filling, road base, etc.
