| 摘 要： | 研究了不同种类的矿物掺合料对混凝土的力学性能和抗氯离子渗透性能的影响。试验结果表明,对单掺矿物掺合料的高性能混凝土而言,在水胶比和坍落度相同的情况下,掺硅灰的混凝土的抗压强度最高,其次是掺粉煤灰的混凝土,掺矿渣的混凝土强度最低。矿物掺合料的掺入能改善混凝土抗氯离子渗透的能力,其中以硅灰为最好,其次是矿渣,粉煤灰稍差。

| Abstract: | The influence of different kind of mineral admixture to mechanical properties and anti chloride ion permeability of concrete is analyzed in this paper.The test results show that for high performance concrete with mineral admixture, when water cement ratio and slum value are kept the same,the compressive strength added with silicon powder has the highest strength,the concrete added with fly ash has the second highest strength,the concrete added with slag has the lowest strength.The mineral admixture can improve the anti chloride ion permeability of concrete as well.Silicone powder has the best result,slag is in the second place,and fly ash is in the third place. |
