粉煤灰在输电线路基础混凝土中的应用研究

Application of Fly Ash on Transmission Line Iron-tower Base

根据宋南220 kV输电线路工程粉煤灰混凝土实验资料及施工情况,并参考有关资料,从粉煤灰的化学成分和与水泥的作用机理,对掺粉煤灰的利弊进行了分析。结果表明,在混凝土中掺入适量粉煤灰可以增加混凝土的和易性,提高强度,提高抗渗透性能和抗腐蚀性能等,并具有显著的经济效益、社会效益和环保效益。

This paper analyzes the benefits and disadvantages of adding fly ash to concrete,from components of fly ash and its action essence with concrete,according to the experimental result and construction quality of applying fly ash to the Songnan 220 kV transmission line. The conclusion is that the operation and intensity and rust-proof could be improving by adding suitability fly ash in it. It is economical and environmental.
