Problems solved by technology

[0005] (2) During normal service, it is easy to cause structural damage due to factors such as drying shrinkage, aircraft impact load, environmental corrosion (carbonization, freeze-thaw, deicing salt, acid rain, etc.);
[0006] (3) In the process of repeated impact and friction between the aircraft tire and the road surface, the anti-skid structure (such as napping, pressing grooves, etc.) is easily damaged, reducing the anti-skid performance and causing flight accidents

Abstract

The invention provides high-bending-resistance abrasion-proof skid-resistance concrete for an airdrome. Each cubic meter of concrete comprises 360kg of cement, 90kg of pulverized fuel ash, 703kg of sands, 1,100kg of continuously graded broken stones with maximal grain size of between 5mm and 25mm, 160kg of water, and 6.7kg of high-efficiency slushing agent. According to the concrete, the pavement has high bending resistance and high wear resistance, and the requirement for pavement structure service can be fulfilled.

Description

technical field [0001] The invention belongs to a new formula of concrete materials in the field of civil engineering. technical background [0002] In recent years, many airport flight areas, including runways, taxiways, aprons, etc., due to improper design and construction, low investment in maintenance and management, long service life, coupled with a substantial increase in flight density, and replacement of aircraft types Due to the increase of post-load and other reasons, the load on the airport pavement is increasing day by day, resulting in a large number of exposed stones, thin layer separation, looseness or damage on the surface of the airport pavement. Such diseases of the airport pavement will not only accelerate the deterioration of the pavement and shorten its service life, but also seriously affect the performance of the airport runway and reduce the safety; at the same time, it will take a lot of manpower, material and financial resources to maintain, affecti...
