中文摘要：

研究了粉煤灰混凝土（Fly ash concrete，FAC）、大掺量矿物掺合料混凝土（Concrete with high content mineral admixture，HCMC）和绿色高耐久性混凝土（Green high durable concrete，GHDC）在（5％MgCl2＋5％Na2SO4）复合溶液中的长期侵蚀作用与干湿循环作用下的化学腐蚀行为。结果表明，在复合溶液的长期侵蚀作用下，GHDC具备比较好的抗腐蚀性能；在复合溶液的干湿循环作用下，HCMC的抗腐蚀能力比较强。因此，GHDC适合于长期的侵蚀环境中，而HCMC则更加适合于干湿交替的严酷条件。

英文摘要：

The durability of fly ash concrete （ FAC）, concrete with high contem mineral admixture （HCMC） and green high durable concrete （GHDC） subjected to the composite solution （5% MgCl2 ＋ 5% Na2SO4 ） under long-term attack and dry-wet circulation were studied. Results show that GHDC has high durability subjected to the composite solution under long-term attack; HCMC has the best performance under dry-wet circu- lation. So GHDC is suitable for long-term attack, and HCMC is suitable for dry-wet circulation.
