Self-leveling super-early-strength quick-hardening material for repairing thin surface layer of concrete pavement and application of self-leveling super-early-strength quick-hardening material
The invention relates to a self-leveling super-early-strength quick-hardening material for repairing a thin surface layer of a concrete pavement and application of the self-leveling super-early-strength quick-hardening material, and belongs to the technical field of concrete materials. The material is prepared from the following components in percentage by mass: 91 to 94 percent of gelling agent, 4 to 6.2 percent of accelerator, 0.05 to 0.15 percent of toughening binder, 0.25 to 0.35 percent of retarder, 0.15 to 0.25 percent of curing agent, 0.25 to 0.35 percent of reinforcing agent, 0.8 to 1.1 percent of expansion anti-shrinking agent, 0.25 to 0.35 percent of friction coefficient reinforcing agent and 0.25 to 0.35 percent of waterproof agent. The problems of rapid strength increase, large brittleness, poor impact resistance, low bonding strength and the like of the repaired thin surface layer are solved, the thin surface layer with high compressive strength, high old and new bonding strength, high breaking strength and excellent toughness is successfully repaired on the concrete pavement, and the repairing process is simple, easy to operate, low in cost, short in period and suitable for large-scale popularization and application. The method has a good application prospect in the field of concrete pavement thin layer repair.
