Multi-source solid waste-based grouting cementing material as well as preparation method and application thereof
A cementitious material and grouting technology, applied in the field of multi-source solid waste-based grouting cementitious materials and their preparation, can solve the problem of poor corrosion resistance, less than 1% utilization rate of red mud, and setting time of grouting cementitious materials. It can meet the needs of engineering applications, solve the problem of solid waste storage, and improve the comprehensive utilization rate.
