ABSTRACT Kaolin is a clay, which when subjected to high temperatures tends to show its pozzolanic properties. In this research, we present the CABLIN INFLUENCE AS PARTIAL REPLACEMENT OF CEMENT IN THE RESISTANCE TO AXIAL COMPRESSION OF THE CONCRETE OF F'c = 210 Kg/cm2, having as main objective: To determine the influence of kaolin as a partial replacement of cement in the resistance to axial compression of the concrete of f'c = 210 Kg/cm2. The kaolin was extracted from the quarry of Llacanora, and then subjected to a furnace at high temperatures, followed by a crushing to obtain Kaolin ash, evidenced by the chemical test of the kaolin sample made that it complied with the characteristics to be used as pozzolanic material. The methodology consisted of making concrete specimens with design f'c = 210 kg/cm2, replacing different percentages (5%, 10% and 15%) of cement by kaolin ash and standard specimens (without incorporation of kaolin). they carried out tests on concrete in a fresh and hardened state, the most important being concrete in the hardened state (ASTM C 39). Finally, the resistance to axial compression of the concrete was evaluated at 7, 14 and 28 days after the respective curing. Based on the results obtained by incorporating the different percentages of kaolin (5%, 10% and 15%), it was observed that when performing the compression test at 7 days, the resistance decreases by 5.53%, 11.01% and 25.95 % respectively with respect to the sample without incorporation and in the test conducted at 14 and 28 days, the resistance increases at 14 days at 8.84%, 25.76% and 36.97% respectively and at 28 days at 31.91%, 75.71% and 86.88% respectively, with respect to the sample without incorporation, with this it is possible to be affirmed that the hypothesis raised if it is fulfilled.
