超细掺和料的填充效应和改善界面结构的作用,可以有效减少水泥石内的开口孔隙和混凝土中的空隙,提高混凝土的密实度,使侵蚀介质和环境水难侵入水泥石和混凝土内部。本次侵蚀180d的试验结果表明,矿渣粉能明显提高抗硫酸盐侵蚀能力,当掺入矿渣粉50%时,抗蚀系数提高36%。 Filling effect of ultrafine admixture and the effect of improving the interface structure can effectively reduce the open pores in the cement stone and the gaps in the concrete, increase the compactness of the concrete, and make the erosion medium and environment water invade the interior of the cement stone and the concrete. The test results of this erosion for 180 days show that the slag powder can obviously improve the anti-sulfate erosion ability, and the anti-corrosion coefficient increases by 36% when it is mixed with 50% slag powder.
