| 摘 要： | 对内掺复合料制成的高性能细石混凝土、普通硅酸盐水泥以及由抗硫酸盐水泥制成的高性能细石混凝土进行了实验对比研究,将其在硫酸钠溶液中进行干湿循环后,对动弹性模量、重量变化率进行测量,结果表明掺加复合掺和料的高性能细石混凝土对硫酸盐侵蚀有较好的抵抗性能.

| Abstract: | Taking three sorts of concrete such as high-performance fine-grained concrete with compound mixture, common silicate cement, and high-performance fine-grained concrete with anti-sulphate ability as investigation target, the dynamic elastic modulus and weight variation rate of these concretes are tested after their dry-wet sycling in the solution of sodium sulphate. The test results show that the former one as listed above possesses a better preventability against the corrosion of sulphate. |

| Keywords: | high-performance concrete dry-wet cycling sulphate |
