SUMMARY:

The construction industry is one of the biggest consumers of energy and materials. Understanding how this consumption occurs during its life cycle is extremely relevant for planning changes for the sector. Thus, considering the importance of analyzing the environmental and economic aspects of these materials from the perspective of the life cycle, this research sought to identify the impacts caused by the production of cementitious materials, in particular the ACII mortar, based on a study of case in a company located in the interior of the Northeast, using a life cycle cost (LCC) methodology. Costs were assessed using a costeffective approach, associating the internal and external lifecycle costs of the crib to the gate. The production of mortars was analyzed using alternative scenarios in order to minimize the uncertainties inherent to the process. For each scenario, mitigating alternatives for the main associated environmental impacts were analyzed, in order to verify their feasibility and effectiveness. The CCV results showed that cement has a high economic and environmental impact and that internal costs are the biggest contributors to the total costs of the process, due to the high amounts of raw materials and inputs used and the company's quest to become more sustainable. The heated economy scenario enabled better results in terms of economic viability, mainly motivated by the low dollar exchange rate. The scenario with economy in retraction, on the other hand, can make it difficult for measures to reduce environmental impacts to be implemented, thus making it difficult to improve production. The use of personal protective equipment, together with the installation of an exhaust system and the replacement of common portlant cement with LC3 cement, proved to be a viable and effective way to mitigate the associated environmental impacts, however, they require many resources and time for its implementation. The study concludes that the inclusion of life cycle thinking in the decisionmaking process proved to be of paramount importance for obtaining a more sustainable production, since it considers the different stages of the life cycle.
