In order to improve the performance of the elastic cement-based grouting materials in deep water environment, experimental studies of the effects of acrylate latex and waterborne latex curing agent on the performance of the elastic cement-based grouting materials are carried out in this research. And the mix promotion of the cement-based cementitious materials is optimized. The testing results show that after admixing waterborne latex curing agent into the grouting materials mixed with the acrylate latex, some acrylate can react with the amido of waterborne latex curing agent by Michael addition and amidation to form polyacrylamide compounds under alkaline conditions of cement hydration, which improves the non-dispersibility of grouting material under water, and the water-air strength ratio of the concretions is more than 90%. At the same time, other acrylate latex is accelerated to form film by waterborne latex curing agent. The interfacial flexural strength between the elastic grouting material and concrete crack interface is greater than 2.0 MPa, and the bearing permeability pressure is greater than 1.2 MPa. Admixing a defined amount of rubber powder into the grouting material can effectively reduce elasticity modulus, improve impact toughness and elastic deformation capacity. The concretion of grouting material has the characteristics of volume stability with no dry shrinkage cracking.
