无碱速凝剂在溪洛渡水电站的运用

Application of alkali-free accelerating agent to construction of Xiluodu Hydropower Station

通过喷射混凝土运用无碱速凝剂在溪洛渡水电站地下工程施工中的实践,以及对无碱速凝剂与碱性速凝剂进行的大量的室内和现场喷射的对比试验,证明:无碱速凝剂比碱性速凝剂有更明显的技术优势并能保证良好的施工环境,可大力推广使用。

Based on the practice of the application of alkali-free accelerating agent to shotcrete during the construction of the underground works of Xiluodu Hydropower Station and a large amount of indoor and in situ comparative tests made on the applications of both the alkali-free accelerating agent and alkaline accelerating agent, it is demonstrated that compared with the alkaline accelerating agent, the alkali-free accelerating agent not only has more technical advantages, but can also ensure a better con- struction environment, and then can be largely popularized in the construction concerned.
