Abstract: Through a collaborative work established between CIDEM and the Laboratory of Construction Materials at EPFL, a new cementitious system based on a synergetic combination of calcined clay and limestone as Portland’s clinker replacement was developed. The novelty of the system was that despite the low clinker content (50%) the resulting cement reached similar performance as pure Portland cement. This paper describes the process of interaction with the Cuban cement industry to introduce this new kind of cement in commercial production. The process included (i) assessment of deposits with suitable clay, (ii) realization of industrial trials for the production and use of the new cement under industrial conditions, (iii) evaluation of economic and environmental feasibility of the new production, and (iv) development of standards covering the composition of the new cement, as well as its use in concrete. Results of the industrial trials are presented, as well as the use of LC3 in practical applications in areas such as structural concrete and masonry. A comprehensive study of durability of concrete made with LC3 has been carried out on concrete under natural conditions in Cuba. All trials prove that LC3 can be considered a high performance, low carbon, low cost material. Keywords: Pozzolana, calcined clays, cement, concrete, standards
