摘要

The present invention relates to an underwater non-separable cement mortar composition and an underwater structure repair and reinforcement method including a sewage culvert using the same, intended to maintain a repair and reinforcement effect for a long time while improving long-term durability. According to the present invention, the underwater non-separable cement mortar composition comprises cement, an aggregate, a concrete reinforcing agent, a reinforcing fiber, a calcium aluminoferrite-based expanding agent, a powdery thickener, a polycarboxylic acid-based water reducing agent, a silicone-based antifoaming agent, a polyether-based antifoaming agent, and a gas foaming material.;COPYRIGHT KIPO 2020
