随着混凝土技术和建筑业发展的需求,高强混凝土得到越来越广泛的应用.高强混凝土的制备通常以降低水胶比或掺入外加剂、矿物掺合料等方式获取,使得其内部结构与普通混凝土不同.然而,粉煤灰作为矿物掺合料在高强混凝土的发展过程中越来越起着重要的作用.在试验室条件下,本文主要研究粉煤灰在高强度混凝土中的蠕变特性及作用机理,最后对于粉煤灰在高度混凝土中的应用前景进行了总结.%With the development of concrete technology and the need of construction, high strength concrete has been more and more widely used in recent years. The preparation of high strength concrete is usually to reduce the ratio of water to cement or admixture, mineral admixture and other ways to obtain that make its internal structure and ordinary concrete different. However, fly ash that is used to mineral admixture is more and more important role in the development of high strength concrete. Under laboratory conditions, this paper mainly studies the creep characteristics and mechanism of fly ash in high strength concrete. To the end, we summarize the application prospect of fly ash in the high concrete.
