Para lo cual, se plantea como metodología investigativa de carácter y diseño experimental mediante un enfoque cuantitativo, evaluando especímenes de concreto elaborados bajo la norma del Instituto Americano del Concreto (A.C.I.) 211 para cumplir el objetivo de mejorar las propiedades físico-mecánicas del concreto sostenible. Los resultados obtenidos en el estudio mostraron que, en los ensayos de resistencia a los 28 días en efectos de compresión simple el concreto grupo 0 (G0) frente al grupo 1 (G1) de 2,7% de caucho molido (CM) obtuvo una resistencia de 22,40 MPa, mientras que en las pruebas de flexión alcanzó un valor flector de 5,01 MPa con la adición de 2,7% de caucho molido. No obstante, para los ensayos físicos de asentamiento del concreto, se evidenció que CM mejora todas las muestras experimentales desde un 6,67%, siendo el valor mayor de mejoría propuesto por el grupo 2 (G2) y el 3 (G3) con 4 ¼&#8221; pulgadas, con un patrón de 3 &#8211;&#8221;.]]></p></abstract>

For which, it is proposed as an investigative methodology of experimental nature and design through a quantitative approach, evaluating concrete specimens prepared under the standard of the American Concrete Institute (A.C.I.) 211 to meet the objective of improving the physical-mechanical properties of sustainable concrete. The results obtained in the study showed that, in the resistance tests at 28 days in simple compression effects, the concrete group 0 (G0) compared to group 1 (G1) of 2,7% ground rubber (CM) obtained a resistance of 22,40 MPa, while in the bending tests it reached a bending value of 5.01 MPa with the addition of 2,7% of ground rubber. However, for the physical concrete settlement tests, it was evident that CM improves all the experimental samples by 6,67%, with the highest improvement value proposed by group 2 (G2) and 3 (G3) with 4 ¼&#8221; inches, with a 3 &#8211;&#8221; pattern.]]></p></abstract>
