Concrete buildings require compliance with procedures, for their correct performance, these range from the correct selection of the material before construction, to the supervision after its casting, among them is the curing, this action consists of maintaining a favorable temperature for the setting of the concrete since, during the setting, its temperature rises. The main objective of this document is to determine the effects of the implementation of Carbon Dioxide (CO2) in the concrete curing process, through tests on samples that allow to establish its feasibility as a curing method. The methodology used is experimentation through observation of laboratory tests in a total of 14 samples. The CO2 curing test applied in the “Geocimientos” Laboratory considered 3 failure dates of 7 days each 310kg / cm, considering a diameter (mm) an Area (mm) 758, a density of (Kg / m3 ) 2292, presents a breaking load (kg) 18040, resulted in the compressive strength of (kg / cm2) 229.7 and (MPa) (2.5),% gave as type of rupture 5, the first phase, in the second phase with the same characteristics, changing the density to 2230 and the resistance of 296.5, (MPa) 29.1 gave 96%.
