摘　　要：四川某水电站高速导流放空洞全长894.24 m,设计要求的衬砌混凝土为C40F300W6。原设计的硅粉抗冲耐磨混凝土存在表面易干缩龟裂、施工难度大等缺点。经多方讨论和论证,最终将其更换为HF抗冲耐磨混凝土,即在混凝土中加入适量的HF外加剂,有效地改善了混凝土拌合物的性能,提高了混凝土的抗冲耐磨性能,并具有水泥用量低、易于施工等特点,取得了较好的效果。The length of the high-speed diversion flood discharge vent of one hydropower station in Sichuan is 894.24 m and the designed lining concrete is C40F300W6.The original design of silica abrasion-resistant concrete has some shortcomings,such as surface shrinkage cracking,difficult in construction and so on.After rounds of discussion and demonstration,HF abrasion-resistant concrete is introduced to replace the original design by adding HF additives,which effectively improves the performance of the concrete mixture and its abrasion-resistant performance.HF abrasion-resistant concrete has the characteristics of low consumption of cement,easy construction and so on.Good results are achieved applying HF abrasion-resistant concrete.
