The housing issue, with regard to constructive inputs used, it is urgent for a paradigm shift that provides the adequacy of the project, many local specificities, as well as playing practice in man in its territory. Considering the Amazon that, like other areas of the country goes through an intense densification of cities, it is still the scene of action, not always positive, large mining projects, which in its wake, bring the issue of disposal of the waste to add the local issues. This work proposes as a solution path for the problem of mineral waste and constructive input: the soil-cement with the addition of mineral waste brick, reject it originates from the southeast of Pará manganese exploration Because the soil with cement brick. waste mineral manganese meet the requirements set by the NBR 8491/2012, presented compressive values above individually to 1.75 MPa, water absorption values lower than 20%, and negligible dimensional change, it still demonstrates its suitability major weather of the region - ultraviolet radiation and humidity - due to the results obtained in the accelerated aging test chamber. The results show promise, and beyond to suit the rules do not interfere significantly in the production process already developed, has large membership possibilities, contributing to building a new paradigm of development.
