The current research focuses on evaluating how the use of Graphene Nanotubes and the SNS 360 System affects structural concrete with a strength of 21 MPa. We use a quantitative methodology of an experimental nature, considering as independent variables the Graphene Nanotubes and the SNS 360 System, and as intervening variables the intrinsic constituent properties of the concrete. The analyzed sample comprises a standard concrete mix and another with nano-additives, totaling 160 prototypes: 140 cylindrical and 20 prismatic. Tests were conducted on compression, tension, and bending resistance at different intervals: 3, 7, 14, and 28 days. We experimented with MWCNT dosages of 0.10%, 0.25%, and 0.05%, adding 1% and 2% of SNS 360 in each instance. The findings suggest that a dosage of 0.05% MWCNT combined with 2% NPF provides the best performance in concrete. Notable data includes a settlement of 3.8”, a unit weight of 2321 kg/cm3, an air content of 1.8%, and a setting time of 125 min. At 28 days, the compression strength reached 330 kg/cm2, tension stood at 27 kg/cm2, and bending achieved 64 kg/cm2. Regarding wear, it exceeded the standard design by 0.078%, and permeability showed a maximum penetration of 19.29 mm. The cost per m³ is S/ 991.71, marking an increase of 33.4% compared to conventional concrete.
