ADHESIVE COMPOSITION BETWEEN MORTAR LAYERS AND REPAIRING METHOD OF CONCRETE

PROBLEM TO BE SOLVED: To provide an adhesive composition between mortar layers which does not inhibit the hydration of cement in mortar or mortar blended with a polymer and which does not cause peeling between the layers of a mortar composition and to provide a repairing method of concrete. SOLUTION: In the repairing of existing concrete in which an adhesive for jointing is coated on the existing concrete, a mortar or a mortar blended with a polymer is coated as undercoating, a reinforcing net material is attached and then a mortar or a mortar blended with a polymer is coated, the adhesive composition between the mortar layers composed of an epoxy resin, a water-dispersible polyamine-epoxy adduct, hydraulic cement and a polyolefin-based pulp-like material is coated on the surfaces of the reinforcing net material and the undercoated mortar or the mortar blended with the polymer.
