在道路建设中使用工业废料粉煤灰不但能节省优质集料,而且对保护环境有相当大的益处。英国对粉煤灰的用途做了许多研究工作,本文汇总了英国在这方面研究的结果,着重介绍粉煤灰的性质以及在道路工程中的用途。一、粉煤灰的物理性质粉煤灰是一种颜色从浅褐色到暗灰色的细粉末,它的颜色取决于灰中未烧透煤的数量。 The use of industrial waste fly ash in road construction not only saves high-quality aggregates but also provides considerable benefits to the environment. In the United Kingdom, much research has been done on the use of fly ash. This article summarizes the findings of the British study in this area, highlighting the properties of fly ash and its use in road engineering. Physical Properties of Fly Ash Fly ash is a fine powder of light brown to dark gray color whose color depends on the amount of unburnt coal in the ash.
