Mix design effect

This database focuses on the effects of mix design parameters on the mechanical properties and damage evolution of recycled aggregate concrete. It contains systematically generated data from mesoscale numerical modelling, including variations in key mix design variables such as recycled aggregate replacement ratio, aggregate grading, mortar content, and interfacial transition zone properties. The database provides corresponding outputs in terms of stress–strain behaviour, elastic modulus, peak strength, damage evolution, and crack development patterns. The dataset is intended to support parametric analysis, comparative studies, and model validation related to the mesoscale mechanical response of recycled aggregate concrete under different mix design scenarios.
