稻壳灰对水泥基材料性能的影响研究进展OA

Rice husk ash(RHA),a by-product of rice husk combustion,possesses unique physical and chemical properties with potential as a cementitious material admixture.Incorporating RHA into cementitious materials not only enhances the resource utilization rate of rice husk as agricultural waste but also helps mitigate the issues of high energy consumption and environmental pollution associated with cement production.This paper systematically describes the physical and chemical properties of RHA and analyzes the influence of rice husk pretreatment methods on its performance.Subsequently,it comprehensively reviews the effects and mechanisms of RHA on the workability,mechanical properties,and durability of cementitious materials.Finally,it summarizes the shortcomings in existing research and outlines future research directions,aiming to provide a reference for further study and application of RHA in cementitious materials.
