不同性能Ⅱ级粉煤灰对混凝土性能的影响
Effect of Concrete Performance by Performances of Different Ⅱ Grade Fly Ash
【摘要】 试验根据四川木里河电站的粉煤灰比选项目,通过测定在粉煤灰采用超量取代法的最优参数下5种粉煤灰掺入的混凝土强度和坍落度,对粉煤灰进行性能检测、XRD分析、SEM观察,确定并分析粉煤灰不同的性能指标、物相及微观结构对混凝土性能的影响。
【Abstract】 According to the fly ash comparison and selection experiment of the Sichuan Muli river hydropower station,the strength and slump of each concrete specimen mixed into each kind of fly ash in optimal parameters were determined by Excess replace method.Through XRD analysis,SEM observation and performance testing of each fly ash,the effect of the concrete performance of different Performance index,Phase and Microscopic structure were confirmed and analyzed.
