Abstract

In this study, the self-healing behavior of fiber-reinforced mortars incorporating crystalline additives under various temperatures and relative humidities was investigated. Optical microscopy, scanning electron microscopy with energy dispersive X-ray (SEM–EDS) analysis, were conducted to evaluate and characterize the self-healing. Pre-cracked reference specimens were cured underwater, while identical specimens were subjected to cyclic temperature and relative humidity. Results show that specimens incorporating crystalline additives exhibited more significant crack-healing after water submersion compared to that of the control specimens. In contrast, no considerable crack self-healing occurred in both control and specimens incorporating crystalline additives when exposed to cyclic temperature and relative humidity. SEM–EDS analysis confirmed that the main self-healing compound was calcium carbonate. It was found that the exposure environments of specimens played an essential role in crack self-healing.
