| titleOfInvention | Admixtures for mortar and concrete, hydraulic compositions, cement compositions and concrete |
| abstract | PROBLEM TO BE SOLVED: To provide an admixture for mortar / concrete capable of obtaining mortar / concrete having excellent chloride permeation resistance without impairing basic performance such as compressive strength, freeze-thaw resistance, and fresh properties. SOLUTION: The polymer particles are hollow fine particles made of acrylonitrile-based polymer or a water-absorbent polymer made of an acrylate / acrylamide-based polymer, and the total amount of silica fume and metacaolin is 100 parts by mass. The silica fume content is 30 to 70 parts by mass, the polymer content is 30 to 70 parts by mass, and the hollow fine particles are 0.5 to 7.5 parts by mass or 0.5 parts by mass with respect to 100 parts by mass of the total amount of silica fume and polymer. A mortar containing 0.4 to 1.2 parts by mass of a water-absorbent polymer, having a mulite content of 5 parts by mass or less and a kaolinite content of 0.1 parts by mass or more in 100 parts by mass of metakaolin. Admixture for concrete. [Selection diagram] None |
