There has been an ongoing concern over the impact of man's uncontrolled exploitation of the environment. The construction sector-field, responsible for the largest consumption of natural resources and also for most of the disposal tossed into the environment seems to be a promising field of research for engineers, architects and other professionals, who seek the development of more sustainable materials and less aggressive means of production. Unburned (ecological) bricks are one of the answers to this problem. Its composition, use and the elimination of the need of sintering make this product meet the three criteria that makes up the tripod of sustainability: economical, social and environmental. The objective of this paper is to evaluate the technical viability of the manufacturing of these bricks at an industrial level, replacing the cement in 50% concentration by blast furnace slag. The bricks manufactured showed high fragility even after 28 days of its manufacturing, breaking easily even at the beginning of the compression tests. As for the water absorption test, the values were 9.4 p.p. above the maximum limit of 20% as set by ABNT NBR 10833. However, these results do not indicate the unfeasibility of the use of slag as a partial replacement for cement.
