Description
Summary:Sustainability has been expected in all fields in recent years, and civil engineering is no exception. Therefore, it is crucial to handle sustainability carefully. Subsequently, research on self-healing materials in concrete has been increasingly focused on this concern. When a crack in the concrete occurs, self-healing materials can repair it. A portion of the damage induced by mechanical loads (pores, microcracks, etc.) can be recovered by these materials, which belong to the superfamily of “smart materials.” The crystalline additive in the current investigation induces artificial healing in concrete. Various methods are used to increase the ability of the concrete to mend itself using various ingredients; in this instance, the user may want to consider environmental exposures and think about employing crystalline additives and nano clay. Cement replacement percentages with nano clay were 2%, 4%, and 6% with adding 1% crystalline admixture. After being subjected to a range of climatic conditions for 28 days, the specimens were pre-cracked to a size of 0.10–0.40 mm. All mixes exhibit a high degree of closure ability and strength-regaining capacity, according to the outcome, given all exposure circumstances. The maximal potential of concrete to seal fractures and regain strength should be demonstrated by using 1% crystalline admixture (CA) and 4% nano clay in all exposure scenarios.
