Resumen
Concrete is, after water, the most used material worldwide and its demand is projected to growth in the next 30 years. Among all concrete materials, cement presents the higher energy consumption and carbon emissions, that's why this industry has been developing several alternatives to gain sustainability. Reduction of clinker ratio by using Supplementary Cementicious Materials (SCM) allows a better use of existing capacities with low investment while a reduction in emissions, costs and energy per ton of cement is observed. The objective of this article is to assess the environmental and economic impact of a new cement with 50% of clinker: Low carbon cement (LC3). A procedure for evaluating sustainable and economic contribution of LC3, while projected demand is satisfied, is designed and applied in several scenarios. The results demonstrate that LC3 introduction is the best option to meet growing demand considering capital investment options in non-developed countries conditions with a reduction of ~30% in carbon emissions, of ~10% in costs and a faster return on investment related to OPC figures in Cuba.
