摘要
高寒地区混凝土面板堆石坝趾板混凝土对抗冻性有特别高的要求,针对抗冻性F300这一关键性的技术指标对其进行配合比对比试验研究分析,拟合得到28d抗压强度与胶水比的关系式,选择出了既满足性能要求又为经济的配合比。
In alpine areas, the toe slab of concrete faced rock-fill dam requires higher frost resistance, the key technical index of F300 was studied to analyse its mix proportion, the relationship of 28 d compressive strength and the gel was achieved, and the optimal mix proportation was obtained.
