模拟酸雨和冻融循环对地聚物砂浆抗压/抗折强度和重金属固化的影响
Effects of simulated acid rain and freeze-thaw cycles on compressive strength and heavy metal immobilization of geopolymer mortar
摘要
Abstract
To explore the changes in compressive and flexural strength of geopolymer mortar mixed with PVA fibers(GPP)and geopolymer mortar mixed with PVA fibers and basalt fibers(GPPB),as well as heavy metal ion leaching,mass loss,and strength degradation,characterization methods such as XRD,SEM,and BET were used to study the microstructural damage evolution of the mortar during acid rain immersion and freeze-thaw cycles.The results showed that the leaching concentrations of heavy metal ions such as Mn,Zn,Pb,Cr,Cd,As,Cu,and Ni in GPP and GPPB geopolymer mortars complied with GB 8978―1996 standard.The freeze-thaw resistance of the mixed fiber geopolymer mortar GPPB was superior to that of the single fiber geopolymer mortar GPP.关键词
