摘　　要：增钙灰是发电厂采用立式旋风炉并添加石灰作为助熔剂时生产出的副产品 ,它的品质与普通粉煤灰在诸多方面存在差异 ,从而限制了增钙灰在混凝土中的应用。本文就增钙灰在混凝土中的应用问题进行了试验研究 ,在体积安定性合格的前提下 ,按照等稠原则 ,采用等量取代掺和方法 。The calcium-added fly ash is a by-product using lime as flux from verticle cyclone stove in the power plant.It was different from the fly ash in many aspects,so that its applications in concrete were confined. In this paper,the study on applications of the calcium added fly ash in concrete was made,and the effects of the mentioned fly ash on durability of concrete were diseussed according to the equal dense.
