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。 The effects of different types of mineral admixtures on the mechanical properties and chloride ion permeability of concrete were studied. The test results show that the compressive strength of concrete with silica fume is the highest for the high performance concrete with single admixture of mineral admixture, with the same water-cement ratio and slump, followed by the concrete with fly ash , Slag concrete slag the lowest strength. The incorporation of mineral admixture can improve the ability of concrete to resist chloride ion infiltration, among which silica fume is the best, followed by slag and fly ash is slightly worse.
