摘要
Abstract
In this paper,the micro-morphology and pore structure of hydraulic concrete under different carbonization conditions are analyzed by SEM(scanning electron microscopy)and mercury stress test.The results show that carbonization can significantly reduce the total porosity,but increase the critical pore size and the most available pore size.In addition,the carbonization reaction significantly changes the crystal structure of the original calcium hydrate,forming a new carbonization layer and its interconnected pores,making it easier for harmful ions in the external environment to enter the concrete,which can be a reference for further revealing the influence mechanism of carbonization on the performance of hydraulic concrete and practical engineering application.关键词
