Resumen
The continuous requirements of concrete, the second most consumed material in the world, are associated with the gradual increase population and civil infrastructure requirements, in fact, the production of this material is linked to the high consumption of the natural resources required for its elaboration (aggregates and cement) [1]. Focused strategies are required in the search for alternative materials that allow mitigating the impacts generated by the exploitation and extraction of traditional components used for the manufacture of concrete [2]. Where, the use of waste materials as substitutes in the preparation of concrete, it is proposed as a strategy of economic and environmental sustainability, in addition to mitigating the overexploitation of quarries [3]. In Colombia alone for 2018, more than 22 million tons of construction and demolition waste were generated [4], 61 thousand tons of tire waste [5]. In addition, digital media such as El Colombiano and El Espectador reported that per year 24 kg of plastic is consumed per person. In which, generally these wastes are handled in an inappropriate way, for such For this reason, they end up being deposited in sanitary landfills and alluvial sources, generating an increase in the degradation of soils and rivers, which is why various investigations propose their use as substitute materials in the elaboration of modified concretes with properties similar or superior to traditional concrete
