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.

INTRODUCTION The use of supplementary cementitious materials (SCMs) to replace part of Clinker in cement is the most successful strategy to reduce CO2 emissions in the global cement industry. The only type of material available in the quantities needed to meet demand is clay containing, kaolinite ,Which can be calcined to produce an effective SCM. LC3 is a modern cement which is a blend of 50% clinker, 15% limestone, 30% calcined clay and 5% gypsum. Here, clinker is reduced by 50% there by CO2 emission can be reduced by 30%. LC3 is a new type of cement that is based on a blend of limestone and calcined clay. LC 3 can reduce CO2 emissions by up to 40%, is made using limestone and low-grade clays which are available in abundant quantities, is cost effective and does not require capital intensive modifications to existing cement plants. The main research activities focus not only on specific thematic areas of cement research but also on production, environmental sustainability and cost effectiveness of this new cement. II. LITERATURE REVIEW 2.1 Parashar et al..(2020): Use new bacterial tool for increasing the strength and rehabilitation of micro cracks management of calcined clay concrete. The overall study indicated that the bacteria demonstrated a helpful role in not only increase the strength of concrete but also helped in the self-healing of cracks. To achieve this phenomenon, Bacillus subtilis bacteria with the count of optimum density 108 CFU is embedded in the normal concrete along with the provision of calcined clay in the replacement of 10%, 15%, and 20% by weight of cement and cured for 7, 14, and 28 days. The specimens were targeted for testing in water absorption and compressive strength. The test result shows that the compressive strength of bacterial calcined clay concrete of the replacements of 10%, 15%, and 20% increased to 25%, 27%, and 28% respectively compared to nominal concrete at 28 days curing condition while the water absorption of the specimens was decreased in bacterial calcined clay concrete compared with calcined clay concrete. Replacement of calcined clay in higher doses leads lesser strength. Moreover, the strength obtained was acceptable as per the IS 456; as strength obtained by waste up to 90% of controlled specimen can be acceptable. The injection of bacterial culture in concrete mix binds the aggregates more closely
