苏丹谢里克水电站火山灰替换粉煤灰可行性的分析与探讨

摘要

In the process of preparing for Shereik Hydropower Project in Sudan , special indoor test on four kinds of local natural pozzolans have been carried out , which including the test for the influence of pozzolanic admixtures on activity index , the test for the effect of pozzo-lan's inhibition on alkali reactivity of aggregate , the test for the influence of pozzolan on concrete strength and hydratation heat of cementi -tious material .Special analyses and research of the feasibility to substitute pozzolan for flyash have been done .%在苏丹谢里克水电站前期筹备过程中，对苏丹当地的四种天然火山灰进行了专门的室内检测试验，包括：火山灰掺量对活性指数的影响试验，火山灰抑制骨料碱活性效果试验，火山灰对胶凝材料水化热和混凝土强度的影响实验，对火山灰替换粉煤灰的可行性进行了专门的分析研究。
