POLYMER CEMENT MORTAR, REPAIRING MATERIAL, AND CURED POLYMER CEMENT MORTAR

摘要

PROBLEM TO BE SOLVED: To provide polymer cement mortar and the like which have excellent characters under a fresh state and a cured state and improves explosion resistance.

SOLUTION: The polymer cement mortar includes water, cement, an expansive additive, a fine aggregate and a polymer. As the polymer, a vinyl acetate/vinyl versatate/acrylic copolymer resin. With cement and the expansive additive as a binder, the polymer/binder ratio is 4.2 to 9.8%. The polymer cement mortar is available as a repairing material for e.g., repairing a cross section of a concrete structure or repairing covering thickness of the concrete structure.
