The purpose of the investigation was to determine the impact of the substitution of fine aggregate from the Aybar quarry and coarse aggregate from the Posada quarry on the compression and settlement of the Trujillo 2022 modified concrete, for which an experimental design investigation was developed, with probability Of sampling. For this, validated sheets were used as instruments that were used to collect the data, the main problem is that for the preparation of conventional concrete, where fine and coarse aggregates, water and cement are mixed for civil and road construction, the vast majority of Builders and citizens obtain non-optimal aggregates to be used in the manufacture of concrete, for which 4 mix designs were made, a standard design, a design with fine aggregate from the Aybar quarry, a design with coarse aggregate from the Posada quarry. and a design with both aggregates, for which 36 15cmx30cm cylindrical specimens cured at ages of 7, 14 and 28 days were prepared, and 12 settlement tests, Obtaining as a result that the concrete with fine aggregate from the Aybar quarry and coarse aggregate from the Posada quarry achieves greater compressive strength at 28 days of curing with a value of 240.5 kg/cm2 and greater workability with 6.4 in. Concluding that the fine aggregate from the Aybar quarry and the coarse aggregate from the Posada quarry do not positively influence the compression and settlement of a modified concrete f'c=210 kg/cm2, Trujillo 2022, these aggregates being optimal to be used to manufacture concrete. for the buildings.
