Concrete is the most widely used material in construction globally, and therefore, the raw materials used in the creation of this material are in high demand. Aggregates such as gravel and sand are extracted from natural deposits that are an important part of an entire ecosystem; therefore, this massive extraction process results in irreversible damage to the environment. The objective is the design and elaboration of a concrete that substitutes part of the coarse aggregate for a material called high density polyethylene (HDPE), without mechanical or economical affectation in the process. The experimental research begins with obtaining the physical properties of the standard concrete (0% inclusion of HDPE), then, a mix design of resistance 175 Kg/cm2 was made for the standard concrete and the study concrete with 10%, 15% and 20% of replacement by coarse aggregate. Then, the HDPE was obtained to demonstrate its viability as part of the concrete, and then the mixes were prepared and tested in the fresh and hardened state. The sample with 15% HDPE replacement increases 28-day compressive strength by 6.93%, 28-day flexural strength by 16.95%, but reduces workability by 12.50%. It also increases the cost per square meter of concrete by S/.10.36 and produces a savings of 43.85 tons of coarse aggregate per cubic meter.
