The experiment results show that these three kinds of additives can improve sulphate attack resistance of the concrete and the order of their efficiency from high to low is silica fume,slag and fly ash;the development of mortar expansion value is closely related to the degree of sulphate attack resistance of the concrete;integrated assessing two concrete properties: mortar expan.
试验结果表明:三种矿物掺合料均可改善混凝土的抗硫酸盐腐蚀能力,作用效率由高至低依次为:硅灰>矿渣>粉煤灰;掺合料混凝土中砂浆膨胀值发展与混凝土硫酸盐腐蚀程度有良好相关性,采用混凝土中砂浆的膨胀值和抗压强度比两项指标能较准确的评价混凝土抗硫酸盐腐蚀的能力。
