碱活性骨料抑制应用研究

Study on Inhibition of Alkali-active Aggregate

碱骨料反应是影响混凝土耐久性的重要因素之一,不同地区骨料碱活性有一定区别,为保工程质量须在工程开工前对工程所用的骨料进行碱活性检测,并对碱骨料进行抑制性控制,从而使项目施工混凝土配合比试验工作顺利进行,为工程选定符合强度、耐久力、经济性要求的工程施工混凝土配合比。

Alkali-aggregate reaction is one of the important factors affecting the durability of concrete.There are some differences in alkali activity of aggregates in different areas.In order to ensure the quality of the project,it is necessary to test the alkali activity of the aggregates used in the project before the project starts,and control the inhibition of alkali aggregate to guide the test of concrete mix ratio in project construction,and select the mix ratio for construction that meets the requirements of strength,durability and economy.
