Análisis técnico y económico, empleando ladrillo triturado reciclado como agregado grueso, para hormigones con resistencia a la compresión de 180 y 210 kg/cm2

Abstract

In this research, it is proposed to make an experimental concrete with recycled material, providing a functionality to the crushed brick as a coarse aggregate for different constructions, which in the future will be friendly to the environment and will also have socioeconomic advantages. The investigation began with the characterization of the coarse aggregates, fine aggregates, and crushed brick residues, through laboratory tests regulated by the NTE INEN, which are required for the design of the concrete dosage, by the ACI 211.1 method, for a 180 kg/cm2 design as 210 kg/cm2 During the experimental process, different mixtures were made, replacing the coarse aggregate in proportions of 0, 5, 15 and 25%, by crushed brick residues and according to the results obtained in the Compressive Strength, Indirect Tensile and Modulus tests. of Elasticity, all these carried out at an age of 28 days of curing, the percentage of reduction of concrete resistance was determined, which gradually decreased, as the crushed brick increased in proportions. Finally, an economic analysis of the concrete design was carried out in each of the mixtures, thus demonstrating economic viability, but without meeting the expected resistance.
