Resumen
Abstract This study combines two techniques for the assessment of sustainability
in cement and concrete production: Life Cycle Analysis and Eco-efficiency. The
first technique is used to assess the environmental impact of Low Carbon Cement
(LC3) production from quarrying to the factory´s gate. The LCA is developed in
order to compare three Cuban cements and its associated impacts: OPC, PPC and
LC3. For that purpose, an inventory is developed using official statistics of the
cement sector, calculated productive and economic indexes and emission factors.
Global warming and energy use, are the main identified impacts. The second
method is employed for the calculation of the improvement potential derived from
the substitution of OPC by LC3 in a model house built with LC3 in Santa Clara
city. A considerable improvement of 54 percent in the eco-efficiency indicator has
been achieved as a result of using blended cement that is a proper combination of
clinker, metakaolin, gypsum and limestone. The results become a challenge for
Cuban construction sector in order to generalize the technology as a sustainable
product from the economic, social and environmental point of view.
