Resumen
Concrete is the most manmade material solution produced and used worldwide. Its cornerstone is the cement composite due to the high emissions level and resources consumption volume. Roughly 5-7% of global carbon dioxide emissions come from cement manufacture process. The far-reaching alternative of replacement a clinker portion in the cement material composition has gained consensus. It becomes relevant in emerging economies since in the short-run there is not widely available ways for increasing the production capacity while diminish the environmental impact with no additional investment cost. Low carbon cement (LC3) is leading the contemporary paths towards facing environmental challenges and resource scarcity. This article aims at assessing the theoretical consideration of replacement of the Cuban traditional cements by LC3 according to housing case studies in Villa Clara province. On the basis of LCA background and the supply chain rationale, a procedure for discussing sustainable contribution of LC3 is designed and applied. Hollow blocks and mortars have been included in the calculations as well as the manufacturing/transportation processes for the entire supply chain of one semi-detached two-storey row houses built in the core of a slum-like settlement at Condado suburb-Santa Clara city. This approach demonstrates that the LC3 incorporation in the Cuban construction sector could afford considerable economic savings with the subsequent contribution in favour of the environment.
