粉煤灰混凝土的研究现状及试验研究前景探讨

Prospect of the Experimental Study and Present Research Situation of Fly Ash Concrete

本文通过分析国内外粉煤灰混凝土抗碳化性能的研究现状及发展趋势，发现，目前混凝土碳化深度主要是通过快速碳化试验的方法，这种方法快捷，但是考虑因素简单，预测结果不准确，而将大掺量粉煤灰混凝土置于自然环境中，可以更全面的考虑自然环境变化因素，分析碳化结果得出碳化深度计算式，可以更准确的预测混凝土碳化深度。进而提高建筑物的耐久性。

In this paper, the writer makes an analysis of the research and development trend of the fly ash concrete carbonation resistance at home and abroad, finds out that currently rapid carbonization test method is mainly used to realize the concrete＇s carbonation depth. This method is quick and simple, but the factors considered are too simple and prediction results are inaccurate. If the concrete with high volume of fly - ash is put in the natural environ- ment, the changing natural environmental factors can be more comprehensively considered. Thus, the carbonization depth calculation formula from the analysis of the carbonization results will used to predicate more accurately the concrete carbonation depth and the durability of buildings will be improved afterwards.
