Fabricación de ladrillos a base de lodos de relaves de mina.

Abstract

This work investigates the possibility of using mine tailings to produce a brick technologically improved through geopolymerization, which present good physical and mechanical characteristics, and avoid environmental pollution. In order to meet this objective was developed three stages: characterization of raw material, selection of the activator solution and factors intervening in the process (temperature, molar concentration, content of solution) for further analysis and mechanical characterization discs made using combinations of the factors selected applying the compression testing diameter using the Brazilian Test (BT) this trial will allow to optimize time and resources in the development of normal size bricks. The results show that the content of solution, the molar concentration and curing temperature are key factors for the development of the chemical process, since they provide satisfactory mechanical behavior to the element. A molar concentration of 15, a content of 26% and temperature of 120° C solution, proved to be the optimal mixture for the production of bricks from mine tailings making a potential candidate for eco-friendly brick-making.
