Abstract
This work aims to investigate the mechanical properties of the cement paste-aggregate interface by combining experimental and numerical approaches. The multi-phase interface microstructure was obtained by X-ray computed tomography (XCT) and submitted to a discrete fracture lattice model for fracture analysis. Apart from the modelling, a benchmark test at the micro-scale has been conducted for the purpose of calibration. With the approach proposed in this work, a framework to model and test the micromechanical properties of the cement paste-aggregate interface at the microscale has been formed.
