当前,以粉煤灰代替部分水泥用于混凝土的生产,在粉煤灰的综合利用中占领先地位。水电部基建司于1983年8月颁发了“混凝土中掺用粉煤灰的暂行技术规定”(试行),对推广该项技术起了积极作用。践实证明,使用优质及合格的粉煤灰是保证粉煤灰混凝土质量的重要条件之一。因此,对粉煤灰原材料进行针对性的研究探讨是很必要的。
At present, the use of fly ash to replace part of the cement is used for the production of concrete, which occupies a leading position in the comprehensive utilization of fly ash. In August 1983, the Department of Infrastructure of the Ministry of Water and Electricity issued the “Provisional Technical Regulations for Adding Fly Ash to Concrete” (Trial), which played a positive role in promoting this technology. Practice has proved that the use of high quality and qualified fly ash is one of the important conditions to ensure the quality of fly ash concrete. Therefore, it is necessary to carry out targeted research on fly ash raw materials.
