<P>PROBLEM TO BE SOLVED: To provide a cement composition for which industrial wastes can be utilized effectively and which has effects such as quick viscosity increase, excellent strength development, an underwater inseparable property and the like and to provide a cavity filling material and its using method. <P>SOLUTION: The cement composition involves cement, slag whose content is 25 pts. or more to 100 pts. of cement, a plasticizer which is an alkali-thickener type polymer emulsion and a curing accelerator. The cavity filling material involves the cement composition. In the using method of the cavity filling material, a liquid A in which the cement, the slag and water are premixed and a liquid B in which the plasticizer and water are mixed are mixed just before use. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
