The present investigation seeks to determine to what extent the added PET influences the modulus of elasticity of concrete of 210 kg / cm2, 280 kg / cm2 and 350 kg / cm2 with respect to traditional concrete. For this, aggregates from the “LEKERSA” quarry located in the El Milagro town center, Huanchaco district, Trujillo - La Libertad, were used. In addition, the Chema Plast additive was used to reduce the water / cement ratio. The cement used was of the Inka Type ICo brand. Specifically in our research, we have prepared 12 mix designs corresponding to the different percentages of added PET and the different f’c required. We set resistances of 210kg / cm2, 280 kg / cm2 and 350 kg / cm2, where 3 dosages for standard concrete were carried out and 3 adding the percentage of additive (5, 10 and 15%). When making the mixtures, the main properties of fresh concrete were determined, such as workability, homogeneity, consistency and density, to subsequently take the samples and cure them correctly. All tests for hardened concrete were performed at the age of 28 days. We determined the experimental static modulus of elasticity of concrete for each resistance as specified in ASTM C-469, and calculated the formula for the theoretical modulus of elasticity proposed by ACI 318-11, 8.5,1 and with respect to the formula of the national building regulations, E-060 reinforced concrete and ACI 318 we conclude that the formulas represent the same and making the comparison the MEE Experimental vary from -11% to + 6%.
