This study aims to present the characterization of mortar with the addition of rice husks biochar in comparison to traditional mortar. For this purpose, a mortar mix for laying was determined. The first mixture consisted of cement, sand, and hydrated lime with a 1:1:4 ratio (cement and sand by volume). The second mixture was produced with the same components and ratios as the first, but with the addition of 10% biochar in replacement to the mass of cement. The objective of this work was to evaluate the physical and mechanical properties of the mortars through tests that determine compressive and tensile strength, consistency index, water absorption by capillarity, and setting time. The results showed that, in addition to ecological benefits, the use of biochar presented improvements in the mechanical and physical properties of mortars. However, there was a slight decrease of 6% in workability.
