粉煤灰资源的综合利用研究现状

Research status of comprehensive utilization of fly ash resources

粉煤灰作为电厂废弃物,已成为我国最大的单一固体污染源,但其中含有大量的有用物质,其高效利用刻不容缓。论文研究了粉煤灰的物理化学性质,比表面积大、粒度细、疏松多孔的物理性质及硅酸铝盐的成分,使其在农业、环保、建材、航天等方面得到了应用,未来将会在更多新领域发挥作用,提高产品性能、降低成本、造福社会。

As a power plant waste,fly ash has become the largest single solid pollution source in China.It is urgent to use it efficiently.The physicochemical properties of fly ash,such as large specific surface area,fine particle size,loose and porous physical properties and the composition of aluminum silicate,have been studied,which have been applied in agriculture,environmental protection,building materials,spaceflight and other fields.In the future,it will play a role in more newareas,improve product performance,reduce costs,and benefit society.
