粉煤灰混凝土从施工技术方面看,与普通混凝土无多大差别,但是从粉煤灰的材料组成、配制和性能方面考虑,与普通砼有明显不同之处,又由于其性能比较稳定,无法进行充分的应用, 本文针对江珠高速三门海特大桥水下灌注桩所用粉煤灰采用物理和化学方法提高其活性的手段进行了一些有益的探索。
Fly ash concrete construction technology from the point of view, with ordinary concrete no significant difference, but from the fly ash material composition, preparation and performance considerations, with ordinary concrete have significant differences, but also because of its relatively stable performance, can not be carried out For full application, some useful explorations are made in this paper by means of physical and chemical methods to improve the activity of fly ash used in underwater piles of Jiangmen Expressway.
