1. Introduction. The incorporation of mineral additions to Portland cement reduces the amount of clinker required in cement manufacture improving the eco-efficiency of this process by lowering both greenhouse gas emissions and energy consumption .These additions also enhance mainly the long-term strength and durability of the material obtained.
