HYDRAULIC COMPOSITION, AND CONCRETE OR MORTAR HAVING EXCELLENT PUMP FORCED-FEEDING PROPERTY

摘要

PROBLEM TO BE SOLVED: To provide a hydraulic composition yielding a mortar or a concrete having improved work execution properties such as pump forced-feeding property in a low water/cement ratio and free from causing the lowering of the strength of hardened body and to provide a hardened body manufactured using the same.;SOLUTION: The hydraulic composition composed of 70 to 95 pts.mass cement, 5 to 30 pts.mass inorganic admixture and 50 to 200 ppm trialkanol amine to the total of the cement and the inorganic admixture is capable of yielding concrete or mortar having improved work execution properties such as pump forced-feeding property in the lower water/cement ratio than that of the conventional ratio without deteriorating the strength of the hardened body.;COPYRIGHT: (C)2005,JPO&NCIPI
