Civil construction has grown inadvertently in Brazil, and, consequently, its demands for raw material. The production of such materials, as to any industrial process, yields wastewater effluents and has, in general, as destination water resources such as rivers and lakes. Nonetheless, government inspection can not keep up with the number of starting companies, resulting in the projection of impunity. The present work, the first of the kind, has the goal of analyzing the some chemical physics aspects of wastewater effluents samples generated from grout industries. The study shows that the pH of these samples lie outside the established limit by the national laws. The extremely alkaline pH and high conductivity of these effluents may cause severe damage to the aquatic environment in which they are disposed.
