According to literature reports, there is also the practice of laying steel plates on the damaged airport runway at present, but the huge airport runway cannot meet the smoothness of the connection between the steel plate and the steel plate, which brings safety hazards to the take-off and landing of the aircraft, and the complexity of the damaged runway The situation made the laying of the steel plate too heavy a task to bring the airfield into service quickly

Abstract
The invention relates to a polymer concrete used to repair airport track, and relative production. Wherein, it uses waste coal ash and sand stone as main materials; uses epoxy resin as adhesive; uses modified polyamine as solidifier; adds some active dilute flexibilizer; the mass percentages of them are (150-200):100:100:(15-30):15. And the invention polymer concrete has high rigidify speed (5-30min), high strength (compression strength at 65-83MPa), and high adhesive with cement concrete.
Description
technical field [0001] The invention relates to the field of materials, in particular to a method for preparing a novel polymer concrete material capable of quickly repairing civil engineering such as airport runways. Background technique [0002] The existing airport runways are basically cement concrete structures. When a war breaks out, the airport must be an important target for enemy military attacks. Once the airport runway is damaged, the runway can be repaired in the shortest time and the plane can take off and land normally. becomes extremely important. If cement concrete is used for repair, the hardening period is long and the construction requirements are high. It takes at least 24-72 hours from repair to normal use. This is obviously not advisable in the extremely urgent situation of the two armies. According to literature reports, there is also the practice of laying steel plates on the damaged airport runway at present, but the huge airport runway cannot meet...
