Resumen
Los materiales poseen una estrecha relación con el presupuesto de cualquier
proyecto constructivo, ya que se consideran desde las primeras fases de producción debido
a su participación en los costos directos de este, por lo que su inefectividad de entrega se
traduce en retrasos en obra, generando tanto consecuencias en la calidad como un
aumento de costos. Los efectos producidos por el cambio climático son consecuencia de
los métodos utilizados por las industrias para satisfacer las necesidades de la población, lo
que va generando las inestabilidades ambientales conocidas. Durante los últimos años ha
tomado relevancia un nuevo concepto de modelo económico: la economía circular, un
sistema regenerativo en el que un producto pasa a estar inmerso en una economía industrial
renovable, a partir de un flujo continuo de materias primas, energía, mano de obra e
información, maximizando así la eficiencia y minimizando la producción de residuos. Para
esta investigación se evalúa la viabilidad técnica y económica de la utilización de un aditivo
controlador de hidratación del cemento presente en el hormigón; esto se espera realizar a
partir de la localización óptima de una instalación donde se trate dicho material, con la
finalidad de maximizar la utilidad del hormigón y, además, minimizar las pérdidas
económicas. Se concluye que es posible instaurar este sistema, lo que permite una
disminución a largo plazo los costos y, además, una reducción notable de los RCD de este
material en el ámbito constructivo.
The materials have a close relationship with the budget of any construction project, since they are considered from the first phases of production due to their participation in the direct costs of this, for which their delivery ineffectiveness translates into delays in the work, resulting in both quality consequences and increased costs. The effects produced by climate change are a consequence of the methods used by industries to meet the needs of the population, which will generate the known environmental instabilities. In recent years, a new concept of economic model has become relevant: the circular economy, a regenerative system in which a product becomes immersed in a renewable industrial economy, based on a continuous flow of raw materials, energy, work and information, thus maximizing efficiency and minimizing waste production. For this research, the technical and economic feasibility of using a cement hydration control additive present in concrete is evaluated; This is expected to be done from the optimal location of a facility where said material is treated, to maximize the usefulness of the concrete and, in addition, minimize economic losses. It is concluded that it is possible to install this system, which allows a long-term decrease in costs and, in addition, a notable reduction in the CDW of this material in the construction field, in addition to the indirect reduction in the use of illegal landfills.
