Abstract

PURPOSE: A crushing agent, containing a mixture of amorphous calcium aluminate with an inorganic sulfate as a hydraulic material and further a specific amount of silica sand as a principal component, and capable of giving improved fluidity with a small amount of water to be used and using the expansion pressure to maximum.
CONSTITUTION: A crushing agent containing (A) 100pts.wt. principal component consisting of 10W40wt% mixture of (i) 50W70wt% quick lime with (ii) 10W 40wt% silica sand and (iii) 10W40wt% mixture of amorphous calcium aluminate with an inorganic sulfate, preferably anhydrrous gypsum, at 1:(0.5W1.5) ratio as a principal component, (B) 3pts.wt. or less dispersing agent, e.g. lignin sulfonate, and (C) 15pts.wt. or less setting retarder, e.g. sodium carbonate. The resultant crushing agent is filled in a hole provided in a brittle material, e.g. rock or concrete, and the brittle material is then crushed by the expansion pressure.
