Concrete is one of the most used materials in the construction industry; being used for the preparation of mixtures with a volume of aggregates of up to 85%, approximately. In the first place, the quarry material was characterized as a global aggregate, knowing its physical and chemical properties; and determining its mechanical properties of structural concrete at 7 and 28 days. The research was carried out using the natural aggregate found in the following quarries of the Marañon River: Puerto Elisa, Municipal Saramiriza, Puerto Bethel, and Puerto Gasolina, extracting approximately 1 ton of aggregates according to NTP 400.010. Then preliminary mixing designs (three controls) were made per quarry to obtain the 7-day f'c a, obtaining only optimal results for the Puerto Elisa and Puerto Gasolina quarries, while the Saramiriza Municipal Quarry and Puerto Bethel Quarry were discarded for having an f'c less than 175 kg / cm2. In the development of final mix designs, two water/cement ratios and four controls were considered for each design; achieving resistances greater than 175 kg / cm2 at 28 days for the Puerto Elisa Quarry and Puerto Gasolina Quarry. Finally, in light of the results, the hypothesis is contrasted.
