In this work three alternatives to improve the compressive strength of clay-based bricks were evaluated. Four mixtures were prepared: the control with only CLAY (without any treatment), one single mixture with the ground and screened clay (CLAY GS ), one binary mixture in which CLAY GS was partially replaced by fly ash (FA) and one ternary mixture in which CLAY GS was partially replaced by FA plus Sugar Cane Bagasse Ash (SCBA). Apparent densities and porosities (ASTM C-20), initial rates of absorption (ASTM C-67) and compressive strengths (ASTM C-67) were determined. The results showed that the use of CLAY GS has positive effects on the density, porosity and compressive strength of bricks made with this material. Bricks made with CLAY GS were 23.08% denser, 20% less porous and 64.41% more resistant to compression than control bricks. According to the ASTM C-62 standard, the bricks obtained correspond to the MW grade. The partial replacement of CLAY GS with 20% FA improves the quality of bricks made only with CLAY GS and with CLAY. According to the ASTM C 62 standard, the bricks made with binary mixture (CLAY GS +FA) have the compressive strength required to be considered SW grade bricks. The addition of SCBA in binary bricks negatively affects their compressive strength.
