前言利用电厂粉煤灰作水工及其它混凝土的掺合料,水泥的混合材,以及其它一些建筑材料的原材料,国内外进行了广泛的研究。由于粉煤灰是十分复杂的东西,各地区的粉煤灰品质有相当差异,而粉煤灰作为混凝土的掺合料,在混凝土中的具体掺入效果,除与粉煤灰的品质有关外,还与混凝土所用水泥性质,配合比及粉煤灰掺入量等因素有关。浙江省水电工程局为了利用杭州半山电厂干排粉煤灰(每年排灰量约十万吨,目前很少利用),作奉化亭下水库大坝混凝土的掺合料,以节约水泥,改善混凝土性能和降低工程造 Preface The use of power plant fly ash as admixture of hydraulic and other concrete, cement mixed materials, as well as some other raw materials for building materials, conducted extensive research at home and abroad. Because fly ash is a very complicated thing, the quality of fly ash in each region is quite different. However, the concrete mixing effect of fly ash as admixture of concrete is not only related to the quality of fly ash , But also with the nature of the cement used in concrete, with the ratio and fly ash incorporation and other factors. Zhejiang Provincial Bureau of Hydropower Engineering in order to use Hangzhou Mid-level power plant dry row of fly ash (annual discharge of about 100,000 tons of ash, with little use), as Fenghua Ting dam reservoir concrete admixture to save cement and improve concrete Performance and reduce engineering
