Correlation of mechanical and microstructure development of early-age concrete by electrical resistivity measurement

摘要：

　　In this work,the correlation of mechanical and microstructure development of early-age concrete was studied through electrical resistivity measurement.The inner enhancement of hydration products other than evolution of pore structure was identified as a vital factor for microstructural development of early-age concrete,which embodies in the increase of tortuosity a and significantly contributes to the growth of mechanical properties.Finally,a correlation between compressive strength and two crucial microstructural parameters (effective porosity φeff and tortuosity a) was built for the three mixes of concrete studied in this paper.
