In the process of industrial production,large quantities of solid wastes are discharged.If they are dis-posed of in a low-resource way such as landfills and stockpiles,it will lead to environmental pollution and other problems.However,solid wastes can be processed to make mineral admixtures.Adding mineral admixtures to concrete not only improves the properties of concrete,but also reduces the amount of cement used and lowers carbon emissions.In recent years,engineering practice has shown that compounding is an important development direction for mineral admixtures.Through compounding methods,various properties of admixtures can be fully u-tilized to achieve effect superposition.In this paper,the physical and chemical properties of a single type of min-eral admixture and its impact on the performance of concrete were introduced.Then,starting from the compound-ing methods of composite admixtures,we reviewed the application of composite admixtures in concrete.Finally,the characteristics of three blending methods were discussed,and suggestions for future research of composite ad-mixtures were proposed.
