中文摘要: |
本文结合200m级高面板堆石坝混凝土面板的特点,对面板材料进行改性研究。采用三复合外加剂、Ⅰ级粉煤灰、硅粉及其增强密实剂、钢纤维与合成纤维6种材料进行试验,取得的研究成果表明,改性材料可以使面板混凝土的抗裂性、抗渗性和耐久性达到更高的水平,保证200m级高坝混凝土面板更加优质、安全、耐久。 |
英文摘要: |
In this paper, the measures for elevating the crack resistance, impermeability and durability of concrete for face-plate in CFRD, 200m in height, are experimentally studied. The results show that the adoption of triple composite additive, Grade I fly-ash, siliceous power and relvant agent for enhancing its strength, synthetic fiber as well as steel fiber are effective in improving the properties of concrete. |
