硅粉掺合料对砂浆抗硫酸盐侵蚀性能的影响

Influence of silica-fume on resistance of sulphate erosion for mortar

硅粉是优良的混凝土掺合料,但对其抗硫酸盐侵蚀机理与效果研究不够。本文结合硅粉砂浆抗硫酸盐侵蚀试验研究,提出了"梯级封堵"的改性思路,并对其抗硫酸盐侵蚀效果进行了分析。

Silica-fume is one kind of outstanding material for concrete. However, study about its mechanism and effect of sulphate erosion resistance is not enough. Based on the experiments and study of mortar combined with silica-fume, this paper puts forward the idea named 'grade filling' to improve mortar property. As well as effect of sulphate erosion performance is analyzed.
