摘要:
将纳米SiO2和纳米CaCO3掺入到普通基础混凝土中,通过室内盐冻循环试验,研究在冻融环境下纳米基础混凝土的抗硫酸盐侵蚀性能。试验结果表明,掺加纳米SiO2和纳米CaCO3可以提高基础混凝土在冻融循环作用下的抗硫酸盐侵蚀性能。当纳米SiO2和纳米CaCO3掺量为2%时,基础混凝土的抗硫酸盐侵蚀性能改善效果最好。
Abstract:
Nano-SiO2 and nano-CaCO3 were added into the plain foundation concrete, and the sulfate corrosion resistance was studied through freezing and thawing test in the sulfate solution. The test results show that the addition of nano-SiO2 and nano-CaCO3 can improve the sulfate corrosion resistance of foundation concrete under freeze-thaw cycles. When the amount of nano-SiO2 and nano-CaCO3 was 2%, the sulfate corrosion resistance of foundation concrete was most obviously improved.
