透水性混凝土的强度受外部接触介质的酸碱性影响很大,为研究透水性混凝土的抗盐腐蚀性能及掺加外加剂后的抗盐腐蚀提高程度,通过素透水性混凝土及分别掺加矿渣微粉和粉煤灰后的浸水、浸盐溶液对比试验,得出:素透水性混凝土抗腐蚀能力较差,掺加矿渣微粉和粉煤灰后,其初期强度和抗硫酸盐腐蚀能力显著提高,掺加粉煤灰较掺加矿渣微粉效果更好。该结论的得出,可为透水性混凝土在复杂地质环境中的应用提供参考。
The strength of water-permeable concrete is greatly affected by the acidity and basicity of the external contact medium. In order to study the salt-resistant corrosion resistance of water-permeable concrete and the degree of salt-resistant corrosion after adding admixture, The results showed that the pervious concrete had less corrosion resistance, and the initial strength and anti-sulfate corrosion ability were significantly increased after adding the slag powder and fly ash, Addition of fly ash mixed with slag powder better. This conclusion can be drawn for the application of permeable concrete in complex geological environment.
