粉煤灰混凝土在桥梁灌注桩中的应用

通过裂区试验方法,对影响粉煤灰混凝土抗压强度的水胶比、粉煤灰掺量、外加剂种类等各试验因素进行了分析研究,总结出粉煤灰混凝土强度在各影响因素下的变化规律,并得出适宜于不同种类外加剂的粉煤灰最佳掺量,并为工程提出最佳配合比。

Application of Powdered Coal Ash Concrete in Bridge Bottling Pile

With the testing method of crack area, the article researches on the factors that influence the compressive strength, including the ratio of water to glue, the blending quantity of powdered coal ash and the type of intrusion aid. Then it summarizes the changing rules of powdered coal ash concrete strength influenced by various factors and the optimum blending quantity suitable for the intrusion aid of various kinds, and provides the best mix proportion for the project.
