“Proposal of concrete design for foundations replacing proportions of hs type cement with recycled glass powder in aggressive soils of the coast of Lima”Abstract
El objeto principal del presente estudio es someter a evaluación la resistencia mecánica de una mezcla de concreto endurecido f´c = 175 kgf/cm2 sustituyendo 5 %, 10 % y 15 % del cemento Portland tipo HS por vidrio pulverizado. La investigación logró el objetivo planteado, además de realizar una comparación con una mezcla de concreto convencional. Utilizando el diseño de mezcla f´c = 175 kgf/cm2, se llevaron a cabo dos mezclas: la convencional y la modificada, reemplanzando el 5%, 10% y 15% del peso del cemento Portland tipo HS por vidrio pulverizado. En primer término, se realizaron las probetas de concreto convencional y, en segundo lugar, las modificadas. Se llevaron a cabo pruebas de resistencias a la compresión, tracción y flexión a los 7, 14, y 28 a partir de lo que señala el Reglamento Nacional de Edificaciones. Por último, realizamos el ensayo estándar para la densidad, absorción y porcentaje vacíos en el concreto endurecido basado en la Norma Técnica Peruana. Al finalizar en la interpretación de resultados determinamos, que para poder tener resistencias mecánicas iguales o mayores que el concreto convencional, debemos remplazar como máximo el cemento por vidrio molido hasta un 5% de su peso y para la densidad, absorción y porcentaje de vacíos un 10% de acuerdo con esta investigación.The objective of the investigation was to evaluate the mechanical resistance of a concrete mixture in the hardened state of f'c = 175 kgf/cm2 substituting 5%, 10% and 15% of Portland cement type HS for pulverized glass, the compressive strength was determined, traction and bending of a conventional concrete mix and then proceeded to compare the mechanical characteristics of both mixes. For the concrete, a mixture design f'c = 175 kgf/cm2was used; Through the mixture design, both the conventional mixture and the modified mixture were made, where 5%, 10% and 15% of the weight of Portland cement type HS was replaced by pulverized glass. The procedure began by making the conventional concrete specimens and then making the modified concrete specimens. The test carried out was the resistance to compression, traction and bending at 7, 14, and 28 days based on the National Building Regulations. Finally, we carry out the standard test for density, absorption and void percentage in hardened concrete based on the Peruvian Technical Standard. At the end of the interpretation of results, we determined that in order to obtain mechanical resistance equal to or greater than conventional concrete, cement should be replaced by ground glass up to 5% of its weight and for density, absorption and percentage of voids a maximum of 10 % agree with this research.
