Abstract: Cement is the most widely used material for construction. However, cement production has a negative impact on the environment, as it is a contributor to global warming. Production of one ton of cement produces about one ton of carbon dioxide. This encourages the searchers to use environmentally friendly materials such as fly ash. The self-healing capacity of Engineered Cementitious Composites (ECC) materials used for new or repairing applications opens up difficult prospects for the use of building materials that can restore original durability levels, thereby ensuring longer service life for less-designed applications and less sensitive performance to environmental induced degradation. One of the possibilities for achieving self-healing capability mentioned above is the use of additives. These additives, when contact with water or air humidity, are capable of forming chemical compounds capable of closing the cracks and thereby ensuring the recovery of an initial level of mechanical performance. The self-healing behaviour of micro-cracks in composite materials was evaluated for the first time through the measurements of compressive and flexural strength tests’. It also focuses on the efficacy of the curing used by the Nano silica solution to stimulate self-healing. Finally, studies were carried out to assess the frequency and prevalence of the behaviour of ECC materials. In addition to the results of ECC studies, the high self-healing ability, which has also been confirmed by experimental results, is believed to contribute significantly to structural strength and sustainability.
