| 中文摘要: |
| 简要介绍了双膨胀水泥混凝土在湖南凌津滩水电工程的应用试验，进行了双膨胀混凝土现场取样检验和原型观测。结果表明：双膨胀混凝土兼有早期和后期微膨胀性能，从而能有效地补偿大体积混凝土的收缩，双膨胀混凝土的强度及其它力学性能与普通混凝土基本一致，均满足设计要求。 |
| 英文摘要: |
| The experience of double expansive cement concrete applied to South Nanjintan Hydropower Project is introduced.The in-situ sampling test and prototype observation data show that this kind of concrete not only expands at the early stage but also sloghtly expands in the later stage,so that the shrinkage strain of the concrete ate the same as that of ordinary concrete. |
