建材生产是大量处理粉煤灰的有效途径之一。除烧结制品外,粉煤灰用于建材生产都有一个活性问题。从六十年代起各同对粉煤灰的火山灰活性开始较系统的研究工作,普遍认为在常温条件下粉煤灰的细度及玻璃体含量是影响其活性的主要因素。我们曾采集了国内31个热电厂的35种 Building material production is one of the effective ways to deal with fly ash. In addition to sintered products, fly ash has an active problem for the production of building materials. From the 1960s, the study on the pozzolanic activity of fly ash began systematically. It is generally believed that the fineness and vitreous content of fly ash are the main factors affecting its activity under normal temperature conditions. We have collected 35 types of domestic 31 thermal power plants
