The study developed in this thesis is based on the performance of experimental laboratory tests for fresh and hardened concrete in order to obtain the values of the different properties in both states. To this end, the Type I Portland cement of the National brand was used, elaborated by the Mixercom company, which is relatively new in the Peruvian market, specifically from Lima, and which has not yet been studied at the thesis level. This cement was subjected to varying times of storage and additionally protected with a plastic container of particular characteristics, in order to retard the chemical changes that naturally occur due to the humidity of the environment over time. Many times a single value or a small group of values do not determine the tendency of a study, even more in the case of experimental processes. For this reason we considered three water - cement ratios (w / c) for the design of the concrete mixture; and three storage times for the cement used, at 5, 30 and 60 days. These variables, added to the additional plastic protection placed at half of the total cement bags used, give us the necessary parameters to assume the trend in the results obtained. Of the most representative properties we can mention that the concrete, object of our study, reached a resistance to compression in the case of concrete made with protected cement under study and with longer storage time (60 days), higher, up to 5.33% over the unprotected (pattern). In the case of tensile strength by diametral compression, it is higher by up to 1.74% with the same characteristics. And in the case of exudation, It decreased by -20.29% in order to ratio (w/c) equal to 0.65, of the concrete under study with respect to the pattern. In general, the results obtained allow to give an evidence of the properties of the concrete in fresh and hardened state, made with this new National Type I Portland cement. In addition, they serve as a background for further investigations with cement mentioned and also for its common use in the construction. Likewise, the variable of the storage time and the additional plastic protection in the cement, helps to determine particular conditions and a reference for its use in the place that gets to be. All the tests were performed in the Materials Testing Laboratory (MTL), for greater reliability in the results.
