Assessing the environmental and economic potential of Limestone Calcined Clay Cement in Cuba

Cement is the most produced material around the world. Developing countries face a growth of population involving an increasing need of infrastructures. Due to this situation, the cement industry needs to find the best comprise between increasing the cement production and without increasing the negative environmental impact. A promising solution has been found in the use of supplementary cementitious materials (SCM), these materials are used to replace clinker in cement because of their pozzolanic reactivity. In this paper, a method was developed to assess the details of the economic and environmental potential of the specific Limestone Calcined Clays Cement LC3 technology in the Cuban context. A comparison with traditional Portland cement and the current commercial blended cement with zeolite (PPC) sold in Cuba was made. The results provide evidenced based data for the development of a strategy to adopt the LC3 technology by the Cuban market This assessment method can then be easily extended to markets in other developing countries.
