Research progress of fly ash-based grouting materials
The research status of grouting materials on fly ash base is reviewed,and the engineering appli-cation of grouting materials on fly ash base is summarized.In order to improve the utilization rate of fly ash in grouting materials,the evaluation of fly ash activation mode is carried out,and the methods to improve the properties of fly ash based grouting materials are demonstrated and suggested,in order to provide theo-retical support for the large-scale application of solid waste.
