摘要
煤炭是当今世界电力的主要来源资源之一,利用煤炭发电产生了大量粉煤灰,如何合理利用粉煤灰已经成为世界性课题。我国是一个超大煤炭资源国,每年都会消耗巨大的煤炭量用以发电等,产生的大量粉煤灰和炉底渣等工业“废料”严重污染了环境,占用了土地资源。在当下大力提倡“绿水青山就是金山银山”的背景下,应更加注重保护环境以及高质量利用土地资源,减少粉煤灰的负面影响。该文基于粉煤灰的物理和化学特性,开展力学性能试验,分析粉煤灰对混凝土力学性能的影响规律,为合理利用粉煤灰提供一定参考。
Coal is one of the major sources of electricity in the world today, but power generation through coal has generated a large amount of fly ash. So how to rationally utilize fly ash has become a worldwide concern. China is a country with massive coal resources, and a huge amount of coal is being consumed every year, like power generation, for example,thereby producing a large amount of industrial “wastes” such as fly ash, blaster furnace slag, etc., seriously polluting the environment and using land resources. In the current context of vigorously advocating “Clear waters and green mountains are as valuable as mountains of gold and silver”, more attention should be paid to environmental protection and high-quality use of land resources, so as to reduce the negative impact of fly ash. Based on the physical and chemical properties of fly ash, this paper conducted tests on mechanical property,and analyzed the influence of fly ash on the mechanical properties of concrete, providing reference for the rational use of fly ash.
