![]() The initial addition of superabsorbent polymers to the mixture results in greater healing compared to the reference samples, making it a sustainable option for the future of cement-based composites.Īs the most commonly used construction material, concrete produces extreme amounts of carbon dioxide (CO2) yearly. ![]() Cracks can still be partially healed after ten years, mainly due to the formation of calcium carbonate crystals, related to the observed regain in mechanical properties measured by repeated four-point bending tests. In this study, specimens were studied after a decade of maturation under different storage conditions to conclude on the self-healing capabilities of the old samples. However, the effects of reduced healing beyond one year are not ubiquitous in the literature. As the ability to self-heal depends on the age of the material, so will the potential influence of added materials to promote this healing. By using a self-healing approach, the service life can be extended, as well as the durability and sustainability of the building material. Without these, the service life can decrease. Unfortunately, they come with a high environmental burden due to carbon dioxide emissions and the need for regular maintenance and repairs. Cement-based materials are the most widely used construction materials in the world for infrastructure works.
