摘　　要：对掺入20%粉煤灰+30%矿渣的掺合料混凝土试块分别采用试验室干湿交替循环、全浸泡和半浸泡不同的试验方法。对若干次试验循环后的掺合料混凝土试块外观变化,质量损失、孔隙率变化、抗压强度的记录和微观结构的扫描,分析和研究试验方法对掺合料混凝土抗硫酸盐侵蚀性能的影响。The concrete blocks with admixtures,which are including 20% pulverized coal ash and 30% gangues,were tested by several methods such as cyclic wetting and drying measure,entire immersion and half immersion measure.Through observing the appearance change,mass loss,porosity change,compressive strength and microscopic structure of the concrete block after certain testing cycle,the influence of different testing methods on anti-sulfate corrosion performance of concrete with admixtures is analyzed.
