摘要
阐述了混凝土的碳化机理,从其内部的物理、化学因素两方面分析了粉煤灰混凝土的抗碳化性能,提出了相应的改善措施。此外,还对粉煤灰混凝土碳化测试和评价方法进行了探讨,并提出从选择合适的养护条件和适当延长其养护时间来进一步完善粉煤灰混凝土碳化测试和评价方法。
The paper introduced the carbonation mechanism of concrete, analyzed the carbonation characteristic of fly ash concrete, proposed the improvement measure. It also analyzed the evaluating methods of carbonation resistance of fly ash concrete, and proposed improvement measure on evaluating methods with proper curing condition and proper curing time.
