The application of waste fly ash and construction-waste in cement filling material in goaf

摘要：

　　As the process of urbanization accelerated,resulting in a large number of abandoned fly ash and construction waste,which have occupied the farmland and polluted the environment.In this paper,a large number of construction waste and abandoned fly ash are mixed into the filling material in goaf,the best formula of the filling material which containing a large amount of abandoned fly ash and construction waste is obtained,and the performance of the filling material is analyzed.The experimental results show that the cost of filling material is very low while the performance is very good,which have a good prospect in goaf.
