摘要
通过对砼试件快速碳化试验结果的分析,得出砼碳化后受压应力———应变关系的三个特征值,并将理论分析的结果与试验结果进行对比,得出碳化砼与未碳化砼相比没有实质性区别,主要不同点为碳化砼峰值强度提高60%,极限应变降低30%,为现有的商业化结构设计和分析程序考虑砼碳化的影响提供了依据.
Through an analysis for results of fast carbonization experiments, three characteristic constants of the relationship between the stress and strain were obtained. After the results were compared with the theories, a conclusion that the carbonized concrete was not remarkably different with the non-carbonized concrete was drawn. The main differences are that the peak strength of carbonized concrete increases about 60% but the ultimate strain decreases about 30%, which provides a basis for current commercial construction design.
