The objective of the present investigation was to determine the influence of the addition of microsilica and the superplasticizer additive on the properties of an anti-washout concrete in the city of Trujillo 2021, for which a pure two-factor experimental design was applied the observation guide was used as an instrument, the sampling was probabilistic and the data analysis technique by descriptive and inferential statistics was used. Nine designs of mixtures were made under the recommendations of ACI 237R-07 to later evaluate their properties in fresh state, such as filling capacity, flow capacity, viscosity, resistance to segregation and resistance to loss of fines; in the hardened state, the compressive strength at 7, 28 and 56 days; finally, the method of placement by the tremie system. The results show that, for an optimal design of 15% microsilica with 1.25% superplasticizer additive, the anti-washout concrete mixtures presented high fluidity, thus achieving: a filling capacity of 618 mm, a passage capacity of 0.82, a viscosity with a time of 14.04 seconds and a resistance to segregation with a VSI value of 0. Likewise, they showed great cohesiveness between their components due to the low percentage of loss of fines of 1.12%, a higher compressive strength of 631 kg/cm2 at 28 days and, in addition to achieving adequate placement under water. Therefore, it was possible to determine the influence of the addition of microsilica and the superplasticizer additive on the properties of the anti-washout concrete.
