In the following investigation, problems that can arise when producing concrete in the presence of high environmental temperatures have been highlighted; In this sense, the study of the behavior of the physical and mechanical properties of concrete f'c = 210 kg / cm2 was carried out with the use of ice water in the manufacture, whose objective was the reduction of the internal temperature of the concrete in the presence of high environmental temperatures of the city of Tarapoto; the aggregate tests were carried out to obtain the mix design and, for the properties of the concrete, comparative analyzes were carried out with a standard concrete and concretes elaborated in a conventional manner with water at room temperature. The tests to which the concrete was subjected were developed in the soil and concrete laboratory of the Faculty of Civil Engineering and Architecture of the National University of San Martin, in the months of November and December of 2018, this being an investigation of the explanatory type, with an experimental design method. The materials used were: ICo extraforte cement and the selected aggregates are frequently used in the different constructions of the city, fine aggregate of the Cumbaza river and heavy aggregate of the Huallaga river. With the use of ice water in the preparation of the mixture, an average consistency of 3.61 "was obtained, demonstrating that with the use of ice water a good workability of the concrete is obtained, without the need to modify the water / cement ratio. The resistance to compression at 28 days, reached an average of 175.15 kg / cm2, being higher than concrete prepared in the same conditions, but with water at room temperature. In addition, it was identified that those specimens that were cured in the open, subjected directly to the weather conditions of the city of Tarapoto, did not overcome the design resistance; holding that there is a need to have an adequate control in the curing of concrete, this being one of the most important phases.
