ABSTRACT The Carbon Fly Ash (CVC) is considered an industrial waste, however, for the development of this thesis is shown as a different alternative addition for the design and construction of concrete structures, in order to increase resistance to Compression and decrease the permeability in the concrete. The present investigation was developed to evaluate the incidence of certain dosages of Carbon Fly Ash (CVC) in the concrete mix design and to evaluate it in the tests of the resistance to the compression; According to NTP 339.034, and the permeability test according to European Standard EN 12390-8. In the same way, the different materials used in the development of the research were analyzed to know their properties, according to the Peruvian Technical Standards, in terms of mixing design, proceeding according to ACI Standard 211 with a water / Cement of 0.55. The quantities of Carbon Fly ash (CVC) were obtained taking into account investigations carried out. According to this, it was determined to use 1.5%, 3%, 4.5% and 6% CVC dosages with respect to the cementing volume of the mixture, in order to generate some kind of incidence on the variables to be studied in this present study. The compression titration was carried out by taking the maximum load: For the Standard Concrete a maximum average load of 218 kg / cm2 for 28 days is obtained, for Concrete + 1.5% CVC yields 220 kg / cm2 for 28 days, for Concrete + 3% CVC yields 227 kg / cm2 for 28 days, for Concrete + 4.5% CVC yields 232 kg / cm2 for 28 days and for Concrete + 6% CVC yields 241 kg / cm2 for 28 days. This means that for amounts that are below 6% CVC, an increase in compressive strength is shown. On the other hand, for the evaluation of the permeability was made by measuring the water penetration: For the Standard Concrete, an average penetration of 137 mm is obtained, for Concrete + 1.5% CVC is obtained 123.5 mm, for Concrete + 1.5% CVC You get 101 mm, for Concrete + 1.5% CVC you get 68 mm and for Concrete + 6% CVC you get 52.5 mm. As can be seen, a considerable decrease is noted as the addition of CVC in the mixture increases.
