Abstract: In recent years, many research papers have been published to investigate self-healing performance incorporating supplementary cementitious materials (SCMs) and crystalline admixtures (CA). It has been confirmed that the self-healing products are changed by the incorporation of SCMs and CA. And, in some papers, it was shown crack width of 0.25 mm
was self-healed incorporating CA. However, most studies using inorganic binders focus on the self-healing performance of cementitious materials depending on the type of inorganic binder, and there is a lack of research on the investigation of self-healing characteristics according to environmental conditions. Since the concrete structure is exposed to various environments, it is necessary to examine the self-healing performance depending on the exposure environment.
In this study, the crack self-healing characteristics of cementitious materials incorporating SCMs and CA were investigated according to exposure environment conditions. Experiments were conducted under three environmental conditions of exposure: Ca(OH)2 solution, high temperature (55 ̊ C) and room temperature environment. XRD and SEM analysis were performed to analyze the components of the self-healing materials.
