摘要:
硫酸盐侵蚀是混凝土耐久性研究的热点之一。矿物掺合料的掺入改变混凝土内部的组成,细化了混凝土的孔结构,对混凝土抗硫酸盐侵蚀起着举足轻重的作用。掺合料的化学组成、细度、掺量等对混凝土抗硫酸盐侵蚀均有很大的影响。外界腐蚀环境的不同,矿物掺合料混凝土抗硫酸盐侵蚀的效果也有显著的差别。大量的研究表明,在连续浸泡的硫酸盐溶液中矿物掺合料只要掺量适当能够提高混凝土抗硫酸盐侵蚀的能力。在干湿循环与硫酸盐溶液共同作用下,矿物掺合料混凝土抗硫酸盐侵蚀的能力有所争议。有些研究表明矿物掺合料能够提高干湿循环条件下混凝土抗硫酸盐侵蚀的能力;然而有些研究却持相反的结论,这需要进一步探索。
Abstract:
Sulfate attack is one of the hot topics in the study of concrete durability. The incorporation of mineral admixtures change inside composition of concrete and refine pore structure of concrete, which plays an important role on the concrete resistance to sulfate attack. Admixture of chemical composition, fineness, dosage, etc have great influence on concrete resistance to sulfate attack. When external corrosion environment is different, the effect of resistance to sulfate attack also has significant difference for mineral admixture concrete. Abundant studies manifest that mineral admixtures can significantly improve the ability of resistance to sulfate attack of concrete as long as the content is appropriate in continuous immersion of sulfate solution. In dry-wet circulation and sulfate solution, it is controversial that mineral admixtures of concrete resists to sulfate attack. Some studies have shown that mineral admixtures can improve the ability of resistance to sulfate attack of concrete. some studies, however, hold the opposite conclusion, which need further study.
