Influência da substituição da cal por resíduos de cerâmica vermelha nas propriedades do estado endurecido de argamassas mistas

Abstract

Considering the large production of red ceramic brick waste (RCBW) and the environmental impacts associated with the inappropriate disposal of these residues in the environment, and the high CO2 emission content associated with the production of lime, this paper analyzes the impact of substitution of lime by RCBW in the properties of the hardened state of mixed mortars. For this, replacements of 20%, 40%, 60% of lime were made by RCBW, in addition to a reference mortar, to verify the influence of these properties through the following tests: flexural tensile strength, compressive strength, water absorption and voids index. The results obtained were satisfactory for most of the mechanical and physical properties of mortars, for all the replacement contents analyzed, with the content of 40% being the most satisfactory, demonstrating the potential of this substitution.
