Description
Technical Field

Since the 1900 year glass blowing was mechanized, the global production of glass and glass products has grown rapidly. Glass is becoming one of the most common materials used in every corner of life, from containers, windows, screens, to medical, electronic instruments, and the like. Glass not only brings convenience to the life of people, but also causes a plurality of problems in the follow-up process. The most important problem is how to effectively and environmentally treat the waste glass. According to official statistical data, about 17.51 million tons of waste glass are produced in the middle of 2014, the recovery amount is about 8.55 million tons, and the utilization rate is 48.33%. The yield of the waste glass reaches 22.12 hundred million tons in China by 2020, and only 9.44 hundred million tons are recycled, and the utilization rate is 44.48 percent. Because the waste glass has differences in color and chemical components, only part of the waste glass can be recycled, and new glass products, glass fiber products and ceramics are produced after specific screening and cleaning, while most of the waste glass is directly subjected to landfill treatment. However, the waste glass is an inorganic nonmetallic material that is not decomposed in a natural state and is difficult to incinerate, and a simple landfill treatment causes land occupation, environmental problems, and resource waste. Therefore, development of a new approach to improve the resource utilization of waste glass is required.
The cemented filling mining process has the advantages of small ore loss and dilution, reduction of surface tailing accumulation, maintenance of stability of underground dead areas and the like, and is widely applied. The large-scale underground goaf filling body consumes a large amount of cement and other cementing materials, the mining cost is obviously increased, and a certain economic burden is brought to mine enterprises. The main oxide composition of the waste glass is SiO 2 CaO and Al 2 O 3 Making it a potential mineral additive useful in the preparation of filled cementitious materials. However, the mere waste glass is less reactive and requiresThe modified solid waste material is modified to improve the hydration reaction activity, and then is matched with various solid waste materials to prepare the cementing material. The invention has important significance for reducing the filling mining cost and improving the utilization rate of solid waste resources. Therefore, the invention aims to research a method for preparing a full-solid waste composite filling cementing material by using waste glass.
