In this thesis, the fine aggregate by granulated rubber volumes (5, 10, 15 and 20%) is replaced. Make a comparative analysis of working properties, forge time, segregation and manufacturing costs of replacing the fine aggregate concrete by volume and crumb rubber in conventional concrete, plus an additional which is the compressive strength. The characterization of the materials used (cement, fine aggregate Cunyac, Huambutio coarse aggregate and granulated rubber) is performed by means of laboratory tests standardized by the Peruvian Technical Standards (NTP), for testing relative proportions for the production of mixtures (mix design) with the ACI method, originally designed to withstand a compressive strength of 210 kg / cm2. The test is divided into three workability properties for better characterization: capacity step, filling ability and resistance to segregation. The test time is determined to forge the vicat needle test and determining the manufacturing cost by unit cost analysis, which is also the additional resistance to compression. These properties were evaluated for each type of concrete so that the concrete was determined by replacing the fine aggregate by granulated rubber volume is the most viable solution to the problem of vibration and crabeater in concrete. Depending on the results obtained in chapter IV the conclusions and recommendations are presented, showing the concrete replacing the fine aggregate by granulated rubber volume has better workability properties of the concrete, time to forge concrete replacing the fine aggregate granulated rubber by volume is greater, the manufacturing cost of replacing the fine aggregate concrete by volume crumb rubber has higher price than conventional concrete and compressive strength is higher in the replacement of fine aggregate by granulated rubber.
