ABSTRACT In this thesis it has been determined the influence on the resistance to axial compression to partially replace Portland cement type I by Diatomite in a concrete 𝑓𝑐 ′ = 210 𝑘𝑔 𝑐𝑚2 Axial compression resistance was evaluated by preparing concrete specimens were tested at the age of 28 days; to begin to research the properties of the aggregates used it was determined by evaluating the physical and mechanical properties according to ASTM / NTP standards, which sets minimum requirements for use in concrete manufacture, testing of concrete was also performed in fresh and hardened, standing the test of resistance to axial compression of concrete (ASTM C39 / NTP 339,034). The methodology of the research was to develop a concrete mix design following the recommendations of ACI 211, with a strength required of 𝑓𝑐 ′ = 210 𝑘𝑔 𝑐𝑚2 to which denominated design pattern from this design develop 4 designs for research, which denominated modified designs, in these designs the partial replacement of Portland cement type I 10% 20% 30% and 40% was held by Diatomite in different percentages based on the weight of cementitious material, keeping constant weight of other materials of the mix design (aggregates and water), the designs were reflected in the development of concrete specimens were then tested. Considering the results it is concluded that there is a positive influence to partially replace Portland cement type I by Diatomite where 10% when replacing Portland cement type I by Diatomite maximum resistance to axial compression 𝑓𝑐 ′ = 210 𝑘𝑔 𝑐𝑚2 isreached represented by 107.73%.2
