Problems solved by technology

[0002] With the rapid development of my country's highway traffic, national and provincial trunk road networks are in a period of rapid construction. Therefore, there is a huge demand for base materials for new roads. If traditional base materials are continued to be used, the consumption of natural raw materials will inevitably increase, which will not only increase It reduces the cost and is not conducive to the sustainable development of the environment
[0003] On the other hand, due to the objective status quo of rich coal, poor oil, and little gas in our country, a large amount of fly ash is produced every year due to the combustion of coal for power generation. A large amount of silicon-calcium slag is produced when the fly ash is consumed. Therefore, the discharge of solid waste such as silicon-calcium slag and fly ash will increase year by year. If these wastes cannot be recycled and cleaned up in a timely and effective manner, it will seriously affect the local environment. Ecological environment, how to recycle these solid wastes, improve the utilization rate of industrial solid wastes, and realize its resource utilization is of great significance

Abstract

The invention provides a stabilizing material as well as a preparation method and application thereof. The stabilizing material is prepared from the following ingredients in parts by weight: 70 to 85weight parts of graded broken stone, 5 to 12 weight parts of silico-calcium slag, 3 to 10 weight parts of fly ash, 1 to 4 weight parts of cement and 5 to 15 weight parts of water, wherein the weight part of the silico-calcium slag is calculated according to the dry basis of the silico-calcium slag. The stabilizing material can be used for road construction; the comprehensive utilization of industrial solid waste can be realized; the road construction cost can also be reduced.
