Quick patching material for cement concrete pavement

Abstract

The invention discloses a quick patching material for a cement concrete pavement, which is prepared from the following components in parts by weight: 500-700 parts of slag powder, 300-500 parts of soluble glass, 120-180 parts of sodium fluosilicate, 50-100 parts of desulfurized gypsum, 0.1-0.3 part of rosin soap, 400-600 parts of recycled concrete fine aggregate and 600-800 parts of recycled concrete coarse aggregate. The quick patching material for the cement concrete pavement of the invention has the advantages of high early strength, high speed of patching the damaged parts of the cement concrete pavement, full utilization of the desulfurized gypsum, the slag powder and other industrial wastes and damaged cement concrete pavement slabs, reduction of the production cost, and little influence on peripheral traffic and the environment in the process of patching the pavement.

Description

technical field [0001] The invention belongs to the field of concrete, and in particular relates to a cement concrete pavement quick repair material. Background technique [0002] With the acceleration of the construction of urban transportation facilities, there are more and more concrete structures, especially the mileage of cement concrete pavement is getting longer and longer. However, with the rapid increase of urban traffic in recent years, many concrete pavements have been damaged prematurely, which has seriously affected the efficiency of traffic facilities and brought great inconvenience to traffic. [0003] At present, ordinary concrete pavement repair materials are used to repair damaged pavements, which generally take many days to maintain before they can be opened to traffic, which will seriously affect the surrounding traffic. The material is used as a raw material, and the production cost is high; therefore, it is urgent to provide a cement concrete pavement ...

AI Technical Summary

Problems solved by technology

However, with the rapid increase of urban traffic in recent years, many concrete pavements have been damaged prematurely, which seriously affects the use efficiency of transportation facilities and brings great inconvenience to traffic travel.

[0003] At present, ordinary concrete pavement repair materials are used to repair the damaged pavement, and it generally takes several days to be opened to traffic, which will seriously affect the surrounding traffic; on the other hand, the existing concrete pavement repair materials mostly use relatively high-priced industrial As a raw material, the production cost is high; therefore, it is urgent to provide a cement concrete pavement rapid repair material that can improve the early strength of the cement concrete pavement repair material, open traffic early and have low production cost
