| 摘 要： | 混凝土中的孔隙和微裂纹是CO2向混凝土内扩散的快速通道,而荷载往往是引起裂缝产生和发展的重要影响因素,因此,混凝土所受荷载的形式和大小必然会影响混凝土的碳化速率。综合评述了目前国内外荷载作用下混凝土的碳化研究进展,总结了不同荷载加载方式和荷载作用下的碳化模型,并对荷载的模拟性研究存在的几个问题提出了一些建议。

| Abstract: | The micro-cracks in concrete are fast diffusion track of CO_2 to the inner concrete,while the loads are important factors causing cracking and crack-extensioa Therefore,the forms and sizes of loads on concrete will inevitably affect the carbonation rate of concrete.This paper reviews the current situation and development of carbonation of concrete under load effect at home and abroad.Some different loading styles and carbonation model are also analyzed. It ends with some views on several issues of load simu... |
