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.
