|
摘要
通过在混凝土中掺入玄武岩纤维和粉煤灰,配制玄武岩纤维高性能混凝土,采用正交试验的方法,研究玄武岩纤维掺量、水胶比、粉煤灰掺量、单位用水量和砂率对混凝土力学性能和工作性能的影响,用极差法分析了各因素对混凝土抗压强度、抗折强度和坍落度的影响规律。根据研究结果,找出了玄武岩纤维高性能混凝土的最优配合比,为实际工程应用提供参考依据。
By using the concrete mixed with basalt fiber and fly ash to make the preparation of high performance concrete of basalt fiber,It uses the orthogonal experiment as the method to find out the different effects on work performance and mechanical properties of concrete,which is related to the amount of basalt fiber and fly ash,water-binder ratio,unit consumption of water and sand rate,The effects of various factors on compressive strength,flexural strength and slump of concrete are analyzed by the method of extreme difference.According to the research results,the optimal mix ratio of high performance concrete of basalt fiber is found out,which provides reference for practical engineering application.
