This research data presents the results of expansive minerals (magnesium oxide, bentonite clay, and quicklime) optimum mix proportions with PC and the establishment of a quantitative approach for correlating autogenous healing to the age of contentious materials. Healing performances were assessed in terms of load recovery, crack sealing efficiency and gas permeability. The microstructure of materials was investigated using XRD, TGA and SEM-EDX.
