Abstract: Cement manufacturing, which is partially responsible for environmental and health risks as well as the greenhouse gas emissions, is a binder industry that needs energy and raw material. To decrease the needing, this study develops nano-modified eco-friendly cementitious composites including industrial solid wastes and/or by-products.
