    The purpose of this experimental study was to analyze the results of the bending test on concrete beams simply adding expanded clay replacing the coarse aggregate. To prepare specimens (beams), it was carried out with brought materials from the quarry "PENINSULA" located in Canton Ambato, Tungurahua Province, in which they moved to the laboratories of the Faculty of Civil Engineering and Mechanics Technical University of Ambato, for their mechanical properties and verify its limits states through various materials testing. Once obtained the mechanical properties of the materials concrete proportions calculated for a design strength fc = 240Kg / cm² using Method Aim Density. According to the dosage obtained specimens (beams) with proportions of 30% and 50% of expanded clay in replacement of coarse aggregate making the material it took volume were prepared. Finally the bending test beams at 7 days, 14 days, 21 days and 28 days of age were performed, thus having an important result on resistance and specific weight of the concrete, since the aggregate is very light and strong
