Due to the importance of maritime structures, it is required that the concrete with which they are manufactured guarantees its impermeability against the waters of the sea, being the ports those that suffer different anomalies when being in direct contact with sulfates and chlorides, which degrade it. progressively causing cracking. For this, the influence of the addition of Carbon Nanotubes (NTC) to concrete mixtures was studied. NTCs have a large specific surface that affects the cement matrix, modifying the hydrated calcium silicates, producing greater cohesion, and increasing the compactness of the concrete. To corroborate the effectiveness of the addition of NTC the properties of the concrete, 2 mix designs were elaborated, one with NTC-0% and another design with the addition of NTC (0.05%, 0.10% and 0.15%). Initially, the materials were characterized and the NTC dispersion process in concrete mixtures was evaluated using superplasticizer and using sonication as a dispersion method. Likewise, settlement tests, resistance to compression, traction, bending and the permeability test were carried out. This work seeks to reduce the permeability of concrete in port structures located in splash and tidal areas, studying different physical and mechanical properties and the economic viability of concrete with NTC; The results indicate that the settlement decreases, the resistance to compression, traction and bending increase, the depth of water penetration decreases, and the cost per m3 is greater.
