PROBLEM TO BE SOLVED: To prevent malodor from being generated by leakage of a static crushing agent and to inject the static crushing agent into a hardened cement body without wasting, when the hardened cement body is crushed by using the static crushing agent.;SOLUTION: In a method for crushing the hardened cement body by using the liquid static crushing agent of which the effective component is an organic ester compound originated from a carboxylic acid, of which the calcium salt is at least crystal, generated in an alkali hydrolysis, the static crushing agent is housed in a container, a hole is formed in the hardened cement body, at least a part of the container is inserted into the hole, and the static crushing agent is gradually discharged into the inside of the hole by pressurizing the static crushing agent through a pressurizing means installed in the container, thereby the static crushing agent being injected into the hardened cement body.;COPYRIGHT: (C)2007,JPO&INPIT
