In the present research, a comparative analysis of the compressive strength of concrete with different curing methods was carried out; at different cure times of 1, 3, 7, 14 and 28 days evaluated with the direct compression machine and the Pundit ultrasonic pulse equipment; in order to obtain results on the variation of the compressive strength under the influence of concrete curing. The concretes were made with Portland IP cement, fine aggregate from the quarries of Pisaq (75%) and sandstone of Vicho (25%), quoin of ¾ “ from the Vicho quarry, because these chosen aggregates complied with the characteristics required by the Technical Regulations 90 cylindrical specimens were made and cured at different times 1, 3, 7, 14 and 28 days to be subject of compression tests in order to determine the resistance of all specimens at 28 days of evaluation. Two chemical additives of different characteristics were used to be compared with a traditional curing to determine the influence of the curing process on strength of concrete; as well as two machines for evaluation. The results obtained show that the compressive strength of concrete is directly related to the method and time of curing, which is why it was obtained: traditional curing presents greater results in a range of 6% to 8% of the compressive strength compared to chemical healers; with 28 days of curing, greater results are presented in a range 22% to 24% of the compressive strength compared to 1, 3, 7 and 14 days of curing and the variation of the results obtained between the direct compression machine and the Pundit ultrasonic pulse equipment is 7% to 9%.
