Embodiment Construction

[0026] The following specific embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0027] Due to the long-term exposure of the airport pavement and the load of the aircraft, maintenance has always been one of the important issues of the airport road department. With the increase of time, the damage of the airport pavement has continued to increase, and the cost of excavation and reconstruction It is very high, and due to the special reasons of the airport, it is not realistic to dig and rebuild. Therefore, the damaged pavement must be repaired. Traditional repair materials cannot solve the problem of repairing thin and ultra-thin layers. If it is allowed to develop, it will increase the disease and even damage the entire board. The present invention is made in view of the above situation, and the purpose is to provide a super concrete repair material which is easy to construct, has short setting time, has a ...

Abstract

The invention discloses a concrete for airport pavement repair and a preparation method thereof. The concrete is characterized by comprising, by weight, 15.0-30.0% of Portland cement, 10.0-20.0% of sulphoaluminate cement, 1-3% of multi walled carbon fiber, 1.8-3.0% of nanometer aluminum powder, 0.5-1.15% of an the active dispersant, 0.2-0.3% of a retarder, 25-55% of quartz sand and 10.0-20.0% of natural zeolite powder. The concrete provided by the invention can repair the airport pavement.

Description

technical field [0001] The invention relates to the field of airport pavement maintenance technology and materials, in particular to a concrete used for airport pavement repair and a preparation method thereof. Background technique [0002] Due to the repeated effects of environmental factors and load factors, especially in winter, after rain and snow, the concrete pavement of the airport is required to be opened to traffic quickly, and a large number of auxiliary materials such as deicing fluid and snow melting agent are used, causing the concrete pavement to be damaged and causing serious damage. The leather and pitted surface expose the aggregate below. After a long time, the large angular aggregate will puncture the aircraft tires. At the same time, foreign objects (FOD) will be produced after the aggregate loosens, which will cause great harm to the aircraft. [0003] There are several categories of materials that can be used for this kind of repair, as shown in the tab...
