Abstract

Cements are materials based on clay and limestone. Its origin was about 4500 years ago and it is believed that they were the basis for the construction of the pyramids in Egypt. As time went by, limestone was calcined, giving origin to the Portland Cement most used today. Its applications are diverse, ranging from the construction industry to the production of sustainable materials. In this sense, this work aims to produce composites of cement loaded with polyaniline and exposure to hydrogen sulfide gas to assess the sorption capacity of this contaminant, present mainly in sewage treatment. The composites were analyzed by resistivity analysis, in order to investigate the influence of PAni in the geopolymer matrix and its ability to conduct electrical energy, after H2S sorption and gravimetry, aiming to observe the increase in mass (g) during the sorption process. All tests were performed in triplicate and the mean, standard deviation and confidence limit were calculated to obtain the reliability of the results.
