PROBLEM TO BE SOLVED: To provide a cement composition and a prolonged storage method thereof which enable the prolonged storage of favorable physical properties such as fluidity, compressive strength, resistance to material segregation, and so forth. SOLUTION: The inclusion of a specific pozzolana impalpable powder in the cement composition and tight closure and storage thereof overcomes the preceding problem. The storage in a tightly closed state characteristically uses a laminated film of a polymer layer and an aluminum layer. COPYRIGHT: (C)2010,JPO&INPIT |
