高性能混凝土抗氯离子渗透性能研究

Research on Chloride Resisting Properties of High-Performance Concrete

研究了矿物掺合料对高性能混凝土氯离子渗透性能的影响,同时对胶凝材料用量以及用水量等配合比参数影响混凝土氯离子渗透性能的规律进行研究,试验结果显示：在矿渣和粉煤灰双掺的情况下,矿渣掺量的增加能明显提高混凝土的抗氯离子渗透性能,而粉煤灰在10%～30%掺量范围内,掺量为20%时混凝土的抗氯离子渗透性能相对较强。

Influences of mineral admixtures amount on anti-chloride-permeability of high performance concrete were researched. Meanwhile, influences of cementing material content and water consumption on anti-chloride-permeability of high performance concrete were researched. The results showed that： in the Case of double mixed with slag and fly-ash, the anti-chloride-permeability of high performance concrete were improved obviously with increasing of slag. Within the mixing amount of fly-ash from 10% to 30%, the antichloride-permeability was higher with 20% amount of fly-ash.
