In the content of this research, I focused on the studies of the resistances of concrete specimens with a resistance of 210 kg / cm2, prepared with three different types of water in their origin (drinking water, sea water that was extracted from huanchaquito and groundwater that was extracted from the Santa Enriqueta district of Chao), using as inputs for its preparation Pacasmayo cement type 1 Extraforte and aggregates from the El Milagro quarry. To realize this research, concrete cylinders were elaborated and tested at ages of 7, 14, 21, 28 days, in such a way that the results for each type of water used in the concrete mixing were analyzed and compared with the ranges established by the rule. Chemical studies were applied to the water to determine what type of contaminating substances or agents existed in its composition to have a data that contrasts with the effects that would have on the strength of the concrete, in the same way the aggregates underwent a characterization study and their physical properties were determined. Using these data, a mix design was made to obtain the proportions that would be used to manufacture the concrete samples. Afterwards, the slum test (settlement) was developed to measure the consistency of the concrete in its fresh state, which was in the range of 3 to 4 ", the test pieces were elaborated with the three types of mixing water sources designed for a resistance of 210.00 kg /cm2 and finally we proceeded to perform the breakage services of the concrete samples to corroborate if the cylinders of 10x20 "reached the designed resistance and what difference occurs between them according to the type of water used. The outcome of the data collected, showed that the drinking water obtained a resistance of 229.50 kg / cm2, the subsoil water reached 197.25 kg /cm2, therefore they are optimal to be used in concrete processing, however the water of sea I do not reach the resistance being this one of 179.00 kg/cm2 reason why it is not advisable to use it for the elaboration of concrete
