The effect of mill-rejected granular cement (MRGC) on enabling concrete to autogenously heal its cracks was investigated. The crack-healing efficiency of concrete containing 5%, 10%, 15%, and 20% wt. of MRGC as a replacement for natural fine aggregate was investigated at the age of 28 days.

Concrete milling is a process that strips layers of concrete from roads, bridges, parking lots, and other paved surfaces to create a smooth surface with plenty of grip. Even though concrete surfaces that have been milled are finished and level, they need maintenance over time, in order to make sure they’re safe and well-cared for.
