In order to minimize the environmental impact generated by tires after their useful life has elapsed, the main objective of the present investigation is to analyze the influence of the mpartial substitution of the fine aggregate for granulated rubber from the mechanical trituration of tires in disuse, as part of the fine aggregate in the manufacture of hollow concrete blocks for non-structural use. The tests corresponding to the standard concrete blocks were carried out, such as: compressive strength at 7 and 28 days of age, dimensionalm variation, warping and absorption, then a comparison was made of this when the fin aggregate was replaced by granulated rubber in progressive percentages of 5%, 10%, 15%, 20%, 25% and 30%, likewise the results obtained with the technical standard E.070 were corroborated. For the elaboration of the present investigation, concrete blocks were manufactured with the following materials: Portland Cement Type IP of the Yura brand, fine aggregate of the combination of the quarries of Cunyac (60%) and Sencca (40%), added coarse with a maximum nominal size of 1/4 “from the Sencca quarry and recycled granulated rubber. Concrete hollow blocks with dimensions 40cm x 20cm x 12cm were elaborated, considering a dosage in volume of 1: 5: 2 (cement: fine aggregate: coarse aggregate), produced in an artisan factory, using a vibrocompactor machine or also called layer and The curing was by immersion. According to the results obtained described in chapter IV, it is concluded that when replacing the fine aggregate with granulated rubber by 5% and 10%, they achieve a greater resistance to compression with respect to the standar block, on the contrary when it is replaced in 15%, 20%, 25% and 30% of the fine aggregate by granulated rubber, the compressive strength decreased with reference to the standard block, and with respect to the Peruvian technical standard E.070, the concrete blocks substituted for 5% , 10%, 15%, 20% and 25% resistances were obtained that are above the minimum resistance (20 kg / cm2), on the contrary the concrete block replaced at 30% does not meet the minimum resistance required by said rule. In the physical tests such as, dimensional variation, warping and percentage of absorption for all the replaced blocks, results were obtained that are below the established in the aforementioned standard, thus fulfilling the established parameters.
