| 摘 要： | 在北方严寒地区修建碾压混凝土坝，首要解决的是高抗冻耐久性碾压混凝土筑坝材料问题。通过研究，提出了解决该问题的有效途径是：低水胶比、适当的掺和料掺量、低VC值、大引气剂掺量、较高含气量。该成果已成功应用在我国西北地区的几座碾压混凝土坝上。

| Abstract: | During construction of RCC dam in severe cold areas, the first problem is to find high-frost-reslstant and durability RCC. The study provides effective solutions of having low rate of water and cement, proper admixture, low VC value, big air-entraining agent and relatively high air content. The technology was successfully applied in RCC dam construction in Northwest of China. |
