Abstract

The country's development is correlated with the advancement of the civil construction industry, but this activity causes environmental impacts. The cement industry makes a major contribution to the world's 𝐶𝑂2 emissions. Seeking to minimize índices2 emission rates, as well as the consequences of global warming due to the annual increase in cement production, several researchers carry out studies on the replacement of Portland cement by alternative materials. Therefore, this work aims to merge and analyze studies carried out by several authors on sugarcane bagasse ash from the Bioenergética Plant, as a partial substitute for Portland cement in the preparation of concrete. In addition, after all the studies were compiled, a case study was prepared to analyze the reduction of economic and environmental impacts by using all the sugarcane bagasse ash generated in a harvest of the industry Denusa – Destilaria Noiva União S /A to replace 10% of cement in the execution of concrete for conventional residential constructions. The results obtained in the surveyed studies demonstrate the effectiveness of partial replacement of ash in cement, mainly in the proportion of 10%, in which the best values ​​were observed in relation to strength and workability of concrete. The case study developed showed the advantages of its use, especially with regard to economic and environmental factors.
