Evaluación de la resistencia a la compresión de especímenes de concreto simple elaborados a partir de agua potable y aguas residuales tratadas de tipo doméstico e industrial, con concentraciones totales de cloruros, sulfatos y álcalis diferentes

Abstract

This research project evaluated the compressive strength of simple concrete specimens made from three types of water, potable water and treated domestic and industrial wastewater, and with mixtures each composed of a different type of water. This study has great importance in the field of civil engineering, mainly in the development of the construction industry in which large quantities of drinking water are used for the elaboration of concrete, so it is worth highlighting and clarifying that due to the limitation of water resources, planet-friendly alternatives must be sought that guarantee its proliferation, which is why the reuse of treated wastewater is proposed, both domestic and industrial. On the other hand, for the optimal development of this research, the total concentrations of chlorides, sulfates and alkalis of each one of the types of water mentioned initially were determined, which are intended to be compared according to the maximum values recommended by the NTC 3459 standard (ICONTEC, 2001) to verify if these waters are suitable and comply with the quality standards required for the elaboration of concrete. Later, the specimens were elaborated from mixtures composed each one by a different type of water and finally the resistance to the compression of the same was evaluated at 28 days. In accordance with what was previously stated, this project allowed the direct evaluation of the behavior of the concrete specimens made from the different types of water by determining their resistance to compression at the age of 28 days of curing to corroborate if they comply with the resistance established in the design and thus conclude that the reinvention in the use of reused water is a profitable path and a safe alternative to use in the production of concrete and in the same way contribute to the conservation of drinking water which is a limited type resource.
