The present investigation comparatively evaluated the results of the compressive strength of carbonated concrete cores made with water from three different sectors of the city of Quillabamba (Quillabamba, Ajuajuyoc and Pintobamba), in addition, it aims to evaluate and compare the effects of the compressive strength of these carbonated concrete witnesses that were subjected to prolonged exposure to carbon dioxide (CO2) at a concentration level of 40,000 ppm in a hermetic carbonation chamber that has simulated a fully saturated environment, this is because the natural concentration of CO2 in the environment is only 400 ppm, in addition, those of concrete witnesses were manufactured with different levels of water pH, which were obtained in three sectors of the city of Quillabamba, with the same mix design ( f´c = 210kg/cm2). Two tests corresponding to compressive strength and carbonation depth were carried out with the chemical reagent called phenolphthalein, all subject to three periods of gas exposure at 7, 14 and 28 days after the curing stage corresponding to 28 days. It was concluded that the results of this comparative evaluation indicated that the effects of carbonation on the compressive strength of the concrete cores depend clearly on the variation of the alkalinity of the concrete and the pH present in the design water of the concrete, in addition of the relative humidity of the environment of the city of Quillabamba.
