大掺量粉煤灰高性能混凝土碳化性能研究

Research on Carbonation Resistance of High-performance Concrete Containing Large Amount of Fly Ash

基于混凝土碳化机理,就粉煤灰掺量、水胶比的变化、激发剂的引入和长期养护等方面,研究了大掺量粉煤灰高性能混凝土碳化深度。并结合大掺量粉煤灰高性能混凝土抗压强度发展特点,对试验结果进行分析和比较,得出一些参考性结论。

Based on the concrete carbonation mechanism,the effects of content of fly ash,water-binder ratio,compound activator and long-term maintenance on the carbonation depth of high-performance concrete are investigated. Experiment results are analyzed and compared with compressive strength development characteristic of high-performance concrete with large amount of fly ash,and some valuable conclusions are gained.
