| Abstract: | With the development of concrete structural technology, high strength is no longer the first important target of high performance concrete and emphasis is more and more put on the unity of mechanical properties, durability and economic benefits of concrete, Fly ash concrete not only can realize the resourceful of fly ash, but also it can solve environment pollution problem, improve concrete quality, add concrete variety, reduce hydrating heat and lower the cost. In this paper, the authors introduced the history, current situation and development trend of the application of PFA concrete, meanwhile analyzed the social and economic significance, properties, application prospect as well as some existing problems of PFA high performance concrete of high replacement levels. |
