Abstract: To solve the problems of long traffic opening time and low durability of the existing cement concrete pavement repair materials, a geopolymeric concrete was developed and applied to rapid repair of cement concrete pavement. The influence of Portland cement dosage and activator to solid ratio on the early strength of geopolymer was studied experimentally, and the mechanical properties, adhesive strength, shrinkage of the geopolymeric concrete were investigated as well. The results show that the geopolymer has the highest early strength when the dosage of cement is 10%, and the activator to solid ratio is 0.75. The 8-hour flexural strength and compressive strength of the geopolymer concrete prepared are 3.25 and 43.6 MPa, respectively, and the 8-hour mechanical properties, adhesive strength, and shrinkage of the geopolymeric concrete meet the technical requirements of repair concrete.
