CEMENT COMPOSITION FOR WATER RETENTIVE HARDENED BODY, CEMENT MILK, WATER RETENTIVE HARDENED BODY AND MANUFACTURING METHOD OF WATER RETENTIVE HARDENED BODY

摘要

PROBLEM TO BE SOLVED: To provide a cement composition for a water retentive hardened body having strength development for a short term and high strength for a long term while having fluidity when cement milk is filled into a void of open-graded asphalt or porous concrete under low temperature circumstances. SOLUTION: The cement composition for the water retentive hardened body where the water retentive hardened body is constituted by filling the cement composition into a void of open-graded asphalt or porous concrete and where portland cement, cement having calcium aluminate and II-type anhydrous gypsum, a zeolite, lithium carbonate, sodium carbonate and sodium tartrate are contained is characterized by containing a lithium carbonate of 1.2-2.4 pts.wt., a sodium carbonate of 0.2-0.4 pts.wt. and a sodium tartrate of 0.1-0.3 pts.wt. based on 100 pts.wt. of the total amount of the cement and the zeolite.
