Had it be the objective of this study the manufacture of soil-cement bricks incorporating the residue mixture, and evaluate the physical and mechanical characteristics as water absorption and simple compression. The experiment was conducted in Sinop-MT, the soil used was a Red-Yellow-dystrophic. The cement used was Portland cement (PC II-32 Z) and the residue from mechanical turning. Soil-cement-residue bricks were made with three levels of residue, partially replacing the soil volume, 5%, 10% and 15%, and a witness without addition of residue, the bricks were molded in hand press and kept moist cure for 7 days. The resistance essay to simple compression and water absorption were performed in accordance with the current regulations. On average resistance values obtained ranged from 0.33 to 0.45 MPa. In the water absorption test of the tested brick have absorptive capacity varying between 7 and 13%. The bricks made from soil-cement-residue mixture did not meet the minimum resistence required by norm, the same was observed in bricks without adding residue, regardless of age assay. Regardless of the residue content inserted the bricks did not reach the minimum resistance required by applicable Brazilian normative, and the analysis of water absorption, the results showed that the soil-cement brick residue framed to the specifications.
