Abstract
The invention belongs to the technical field of airport parking lane maintenance, and particularly relates to a rapid repairing material for an airport parking apron and a preparation method thereof.The repairing material is prepared from the following components: high-belite sulphoaluminate cement, wollastonite powder, a powder defoaming agent, a water repellent, quartz powder, acrylic acid redispersible latex powder, a polycarboxylate superplasticizer, a medium-term early strength agent, an early retarder, low-viscosity HPMC, fine aggregates, heat-resistant fibers and polymer fibers. The repairing material disclosed by the invention has high bonding force, and is free from hollowing and cracking after being repaired; the strength can reach C65 or above; the toughness is high, and the impact resistance is more than 20 times that of common concrete; low-temperature cyclic freezing and thawing at -40 DEG C or below can be resisted; acid and salt corrosion resistance; thermal expansionand cold contraction coefficients are consistent; synchronous displacement between cold and hot circulation and original concrete is ensured; and moreover, navigation can be performed only by maintaining for 2 hours after construction, and therefore, the rapid repairing material for an airport parking apron is suitable for rapid maintenance and repair of airport roads.
Description
technical field [0001] The invention belongs to the technical field of airport apron maintenance, and in particular relates to a quick repair material for airport aprons and a preparation method thereof. Background technique [0002] Most of the airport apronways in my country are rigid pavements of cement concrete, which have the characteristics of high strength and good durability. However, after long-term use, the pavement is subjected to long-term loads of aircraft, as well as wind and snow, alternating cold and hot weather, etc. The impact of changes and other conditions has caused cracks, breaks, edge drop and corners on the airport pavement, and even worse conditions, which may affect the normal operation of the airport, and in severe cases, it will affect the take-off of the aircraft. Therefore, for the maintenance of the airport pavement, the task of repairing the airport runway and the repairing of the airport road can be described as a top priority. [0003] The m...
