<p><P>PROBLEM TO BE SOLVED: To provide a cement hardened body having excellent explosion resistance. <P>SOLUTION: The explosion resistant cement hardened body contains waste tickets. It is preferable that the explosion resistant hardened body is carbonated and has 35-60% water/cement ratio and≥30 N/mm<SP>2</SP>compressive strength. The method of producing the explosion resistant cement hardened body includes: mixing a cement composition containing the waste tickets and cement with water to prepare a cement kneaded material; pouring the kneaded material into a form and curing it; and removing it from the form and curing the resultant formed body. It is preferable that the cement kneaded material contains at least one kind of fine aggregate, coarse aggregate and an organic fiber. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
