The objective of this study is to compare the compressive strength of concrete samples (Cement - Sand) f'c=210kg/cm2 and f'c=175kg/cm2 made with different types of water (Potable, Itaya River, Nanay and Amazon). using Andean Type I cement and fine aggregate to determine if their uniaxial resistances have a significant difference. To carry out this investigation, concrete test tubes were made at ages of 7, 21 and 28 days in order to see the variation of the results and thus be able to compare them with what is established by the standard. No studies were carried out on water because they wanted to see the results of the resistance of a conventional concrete like any person or company that carries out at the time of mixing. The corresponding tests established by the standard were carried out on the fine aggregate. Then the concrete workability test (slump test) was carried out to measure the consistency of the fresh concrete. Afterwards, the concrete test tubes were manufactured using the different types of water in 210kg/cm2 and 175kg/cm2 designs. Once the curing days established by the standard were completed, the compression resistance tests were carried out to confirm if the samples reached the expected resistance and thus know if there is a significant difference. The results of resistance to uniaxial compression of concrete (Cement - Sand) tested and cured under the standards up to 28 days gave the following results: Design f'c =210kg/cm2; The one made with drinking water f ‘c =349kg/cm2, The one made with water from the Nanay river f ‘c =332kg/cm2; The one made with water from the Itaya river f ‘c = 315kg/cm2 and the one made with water from the Amazon river 349kg/cm2. Design f'c =175kg/cm2; The one made with drinking water f ‘c =269kg/cm2; The one made with water from the Nanay river f ‘c =259kg/cm2; The one made with water from the Itaya river f ‘c xvii =239kg/cm2 and the one made with water from the Amazon river f ‘c =256kg/cm2. Analyzing the results, all the results are acceptable since they exceed the design f'c. It is also seen that the design made with water from the Itaya river has a lower average compressive strength, the design made with Amazon River water has the highest average compressive strength, none of the tests carried out are below the design established. Finally, it is concluded that it is possible to use the different types of water (Potable Water, Nanay River Water, Itaya River Water, Amazon River Water), which was seen in this study in the preparation of concrete. Therefore, THERE IS NO SIGNIFICANT DIFFERENCE when using different types of water (drinking water and surface water) in the mix design which responds to our hypothesis.
