The objective of this study is to compare the results of the compressive strength test of a conventional concrete (cement-sand) F’c= 210kg/cm2 with different brands of cements with A/C ratios of (0.58,0.60 and 0.62) and with two types of aggregates (Sand from RÍo Nanay and White Sand from quarry) The sample consisted of 162 concrete specimens with different brands of cement, with different A/C ratios and two types of aggregates, for which breakage or uniaxial testing was carried out at ages of 7, 14 and 28 days. Descriptive statistics were applied for information processing; and, the hypothesis was verified at the moment of seeing and analyzing the results of the tests that were carried out. The results of this investigation showed that the Amazonian cement TYPE GU reaches its highest resistance with river sand if an A/C ratio of 0.58 is used. In this investigation, a resistance of 271kg/cm2 was reached, surpassing the design with white sand with the same ratio, which reached a resistance of 256kg/cm2. Analyzing the results, all are acceptable since they exceed the design F’c. Finally, with the study carried out it can be concluded; that if you can use the different brands of cement (APU, AMAZONICO AND INKA), for the preparation of concrete (cement-sand). Therefore, THERE IS A SIGNIFICANT DIFFERENCE when using different brands of cement in the mix design, which responds to our HI hypothesis.
