南水北调中线北京段工程混凝土骨料碱活性分析及抑制碱活性效能研究

南水北调中线北京段工程混凝土骨料用量大,要求标准高,对骨料的碱活性反应要求更为严格.文中详细介绍了北京段骨料的碱活性试验与分析以及抑制碱活性效能研究,希望对今后类似工程用提供参考借鉴.

Analysis and research on alkali activity of concrete aggregate and inhibition of its effectiveness for construction of Beijing-section within Mid-route of South-to-North Water Transfer Project

During the construction of Beijing-soction of the Mid-route of the South-to-North Water Transfer Project, a large amount of high standard concrete aggregate is used, for which the requirement on the alkali-reactivity of the aggregate is quite strict. The analysis and research on alkali activity of the aggregate and the inhibition of its effectiveness for the construction of Beijing-section within the Mid-route of the South-w-North Water Transfer Project are described in detail herein, so as to provide some references for the similar projects in the days to come.
