小浪底工程中大掺量粉煤灰混凝土多种配合比性能的试验研究表明,掺粉煤灰可显著降低混凝土的单位用水量,改善混凝土拌和物的和易性;随着掺量的增加,用水量减少,90天后能逐渐接近并超过纯水泥混凝土的强度。粉煤灰的大量使用,不仅可以减轻它对环境造成的污染,而且还能产生显著的经济效益和社会效益。
Experimental study on various mixing performance of high volume fly ash concrete in Xiaolangdi Project shows that mixing fly ash can significantly reduce the unit water consumption of concrete and improve the workability of concrete mixture. With the increase of dosage, After 90 days, it can gradually approach and exceed the strength of pure cement concrete. The extensive use of fly ash can not only reduce its pollution to the environment, but also produce significant economic and social benefits.
