demostrar a través de la investigaciónResumen
Este estudio tiene como objetivo comparar a través de la investigación el uso de hormigón agregado reciclado para minimizar la eliminación indebida. Sin embargo, este hormigón producido con agregado reciclado presenta varios problemas, como una menor masa específica, pérdida de trabajabilidad y alto consumo de cemento debido a la alta absorción de agua, además de presentar una mayor porosidad, en comparación con el agregado natural. Debido al mortero adherido a su superficie, que promueve el aumento de la relación agua/cemento, hay una disminución en la masa específica de este hormigón producido a partir de áridos reciclados. Por lo tanto, la resistencia a la compresión de este hormigón tiende a disminuir con el aumento del contenido de reemplazo del agregado natural por el agregado reciclado. Otra posible solución es el uso de látex, que son dispersiones de partículas de polímeros orgánicos en agua, fluidos lechosos que tienen coloración blanca. Sin embargo, solo el 5% de estos látex se pueden usar con cemento Portland. Uno de los látex más utilizados para el hormigón es el látex de butadieno estireno, que se analiza en este estudio. Los estudios muestran un aumento máximo en la resistencia a la compresión del 20,95%, utilizando un contenido de látex del 15%, un aumento máximo en la resistencia a la flexión del 36,35% para el hormigón convencional, con el objetivo de aumentar el uso de agregado de hormigón reciclado en la construcción civil.
