Análisis de un hormigón permeable mediante la sustitución parcial del agregado grueso con material reciclado de Obra civil

Abstract

The development of modified materials with the use of waste in construction projects start by necessity to solve pollution problems, caused by not having adequate management of this solid waste left over from construction work (block, brick, paving stone, concrete, etc.). Therefore, this recycled material was used in this investigation to determine its resistance to compression and permeability (K) using the elaboration of a pervious concrete; which, later on, can be used in different applications. First, specimens of the standard sample (MP) were prepared, using coarse aggregate (AG), which complied with the standards and parameters established in ASTM C 39 and ACI 522R-10. Then, modified pervious concrete (HP) specimens were manufactured and identified as modified specimens (MM), where the AG was partially replaced by recycled aggregate (AR) at 20% (AR20) and 30% (AR30), from which the same properties of the MP were determined for later comparing. The AR20 and AR30 specimens in the compressive strength tests show a decrease of (20.19 to 9.42)MPa as the percentage of AR increases; however, the permeability is inversely proportional to the increase of AR.
