Abstract
The invention relates to a polymer concrete mortar for quick patching of cement concrete pavements and a preparation method thereof. The material is prepared in proportion by taking industrial waste flyash as a main raw material, a polyurethane-modified epoxy resin as a binder, a modified polyamine as a curing agent, and adding a right amount of an active dilution toughening agent. The specific proportion is accounted as: in parts by weight, 200 to 300 of flyash, 100 to 150 of polyurethane-modified epoxy resin, 100 to 150 of polyamine, 15 to 30 of a diluent, and 5 to 20 of an exciting agent. The patching material for cement concrete pavements prepared by the invention has the advantages of rapid hardening early strength (curing time: 10-40 min; compressive strength of 65-75 MPa), strong bonding power with cement concrete so that the construction can be performed in wet and low-temperature conditions, high cured strength, good toughness, smooth surface, and excellent abrasive resistance and shock resistance.
Description
technical field [0001] The invention relates to the field of materials, in particular to a preparation method of a novel polymer concrete mortar material capable of rapidly repairing cement concrete pavement and other civil engineering. Background technique [0002] Since the reform and opening up, with the rapid development of the national economy, the road traffic volume and vehicle load have increased day by day, and the damage of the pavement structure has been accelerated. The pavement is damaged to varying degrees when it is far from reaching its design life. According to incomplete statistics, about 20-30% of the existing cement concrete pavement in my country will be repaired and improved. [0003] The damaged concrete pavement needs to be repaired, but due to the needs of the current traffic network, it is not allowed to close the traffic for a long time when repairing the road surface in use, especially the highway and urban road. Therefore, the research on rapid...
