白石水库建在多泥沙河流上，泄水建筑物的抗冲磨问题是设计的关键．硅粉混凝土是一种新型抗冲耐磨材料，具有强度高、抗磨蚀、抗空蚀能力强，以及施工简单，与基底混凝土适应性好、无毒、成本低等优点．为此，白石水库大坝底孔选择硅粉混凝土为抗冲磨材料，并对其进行了试验研究，得出施工用硅粉混凝土配合比，其水泥用量仅为240kg／m3左右，降低了水泥水化热温升，有利于防止混凝土裂缝的发生． Whitehead Reservoir built in the multi-sediment rivers, anti-scouring structure of the building is the key issue of the design. Silica fume is a new type of wear-resistant materials, with high strength, abrasion resistance, cavitation erosion resistance and simple construction, good adaptability with the base concrete, non-toxic, low cost and other advantages. For this reason, silica fume concrete is selected as the anti-abrasion material in the bottom hole of Baishi reservoir dam, and the experimental study is carried out. The results show that the mix proportion of silica fume cement used in construction is only about 240kg / m3, Hydration heat temperature is conducive to preventing the occurrence of concrete cracks.
