In this thesis, the main objective of this work was to perform a comparative analysis of the settling times and compressive strength of a concrete f'c 210 kg / cm2 of the Pacasmayo and Qhuna cement. Different concrete mixing designs were used for each type I and Ico portland cement, since each one presents different chemical and physical conditions, but with different water-cement ratios such as: 0.40, 0.48 and 0.56 and keeping a constant slump for each type of concrete (Slump: 3 ““- 4““). This way obtain a plastic consistency. In order to reach this objective, the cylindrical specimens, whose dimensions were 15 cm x 30 cm,,, were taken as material of this investigation and three samples of specimens or concrete witnesses were carried out in which they were tested at the ages of 3, 7, 14, 28 days. These tests were performed at the Universidad Nacional de Ingeniería, demonstrating that Qhuna cement is the most suitable if a rapid stripping is desired, taking into account the requirements given by the standards both meet the requirements with a ratio a / c = 0.40. As a result of the process of analysis of compressive strength, it was possible to know the most optimal ratio of water to cement, because with this relationship we were able to cover all percentages of concrete hardness. This cement water ratio of 0.48, in Pacasmayo cements at 28 days covered a resistance of 210 kg / cm2 however in Qhuna cements covered a resistance of 270 kg / cm2 at 28 days of curing.
