In the present thesis, an investigation was carried out regarding the analysis of the dynamic modulus of elasticity of a concrete F'c 280 kg/cm2, and 1.5%, 3.0% and 4. 5%, Sika® Fiber CHO 80/60 NB brand, to reinforce the concrete, this has utilities in traditional and industrial concrete slabs, precast concrete elements, specially glued to allow its homogenization during mixing, thus avoiding the agglomeration of individual fibers, these add ductility, toughness and a high bearing capacity in a wide range of applications. The main objective of this study is to determine the variation of the dynamic modulus of elasticity for our concrete, adding the additive mentioned above, with which we intend to elaborate a comparison with corroborated information, between destructive and non-destructive tests; with this we aspire to find answers through the analysis of the static modulus of elasticity, using the compressometer and to find the dynamic modulus of elasticity using the ultrasonic resonance equipment Pundit ® Lab. In the procedure we determined the modulus of elasticity by analyzing the characteristics of fine and coarse aggregates, using the Peruvian Technical Standard NTP 400.012; we selected the total number of concrete specimens needed, referring to the ASTM C-192 Standard; we found the compressive strength using Sol Portland Type I cement with the addition of drawn steel fibers at 1.5%, 3.0% and 4. 5%, according to the ASTM C-31 standard; we determined the static modulus of elasticity of concrete using the ASTM C-469 standard, with the destructive test through the use of the compressometer; we also found the dynamic modulus of elasticity of concrete based on the ASTM C-597 standard, with the non destructive test through the use of ultrasound; then we evaluated the results through comparative tables and graphs of the compression cores and ultrasonic resonance frequency. The methodology used making a comparative of results, which will conclude as a basic and applied project because at the beginning we will collect information 12 or investigate theories to then make the designs, in order to achieve better results of the dynamic modulus of elasticity. Finally, we will conclude with the comparative graphs that show us the value of the modulus of elasticity at 7, 14 and 28 days in different percentages of addition for the workability of the mix design of F'c 280 Kg/Cm2
