Summary:PROBLEM TO BE SOLVED: To provide extra quick hardening grout mortar which further enhances the required performances such as fluidity, bleeding prevention or secured sufficient pot life, provides stable initial expansivity and attains the improvement of crack resistance in a dry state. SOLUTION: The extra quick hardening cement composition which is a main component of the grout mortar contains cement, calcium aluminate, gypsums, peroxide material, setting modifier and fluidizing agent. Among those, a bonding material is composed of 50-90 pts. cement, 5-25 pts calcium aluminate and 5-25 pts. gypsum in 100 pts total, and the peroxide material of 0.005-0.5 pt. is blended based on 100 pts. bonding material. The extra quick hardening grout mortar is prepared by kneading water and an extra quick hardening mortar composition comprising the above cement composition and fine aggregate. Besides, a cement-hardened body is composed by using the grout mortar. COPYRIGHT: (C)2006,JPO&NCIPI
