  Cement is the most used material in the world.Thanks to its low cost, it is he only material that can satisfy the growing demand for infrastructure, especially in developing countries.However, the production of cement is responsible for about 7% of the global emissions of carbon dioxide in the atmosphere.Because of such a ubiquitous presence in our environment, only a small decrease in its production would have a significant impact in terms of greenhouse gas emissions.To this end, one option is to improve the hardness and toughness of cement.Indeed, harder and tougher cement would allow using less material while achieving comparable mechanical properties.Moreover, an increased resistance to fracture and permanent deformations would improve its longevity, making it more sustainable.
