Abstract: The hydration degree and compressive mechanical properties of concrete are evaluated in relation to microstructure composition at three curing ages. The analysis focuses on hydration and compressive load-bearing mechanism at the microstructural level. A concrete micromechanism that allows explicit parameters of pore distribution and pore diameter is investigated. Variations of concrete microstructure are measured and analysed over a range of curing ages. Results show that (1) different curing periods have significant effects on the hydration degrees and microstructure of concrete, (2) variations of hydration degrees are the basic reason of changes of pore structure and (3) type of porosity and pore diameter affects mechanical properties of concrete. Microstructure-behaviour relations are established to determine hydration degree and compressive mechanical properties, and facilitate microlevel studies on concrete properties for target-specific applications.
