![]() ![]() 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. ![]()
