The present thesis performs the study and analysis of the properties of the Concrete Pattern with 1% Plasticizer Additive and Hydrated Cal 10%, 20% and 30% considering the a / c ratios: 0.60, 0.65 and 0.70 for curing ages of 7 , 28, 45, 60 and 90 days. It also emphasizes the need to use Hydrated Lime in concrete, for its qualities to improve its behavior. This research involves a progressive development in concrete mix designs, both in the fresh and hardened state, using the Global Aggregate Method, in which it is necessary to find the standard water and standard aggregates that guarantee maximum compactness and compressive strength , In the laboratory several tests of properties of the aggregates (sand, stone), hydrated lime and in the different types of concrete to the fresh state (Settlement, Fluidity, Air Content, PUC and Initial and Final Forge Times) and to the state Hardened (Compressive Strength, Diametral Traction, Elastic Modulus and Absorption Rate). For these last tests a total of 545 specimens were prepared in the respective tests. The materials used were: Plasticizer Additive, Thin and Coarse Aggregates and Hydrated Lime. The analysis shows that the optimum percentage of Hydrated Lime in Concrete with Additive is 10%, with which the highest compressive strengths were obtained at different curing ages and lower Absorption Percentages with respect to the standard concrete. When using higher doses of Hydrated Lime (as 20% and 30%) in the Concrete with Additive, slight increases of resistance to Compression and Elastic Modules are obtained with respect to the standard concrete. In the fresh state the Unit Weights and Initial / Final Forcing Times of Concretes with Additive and Hydrated Lime at 10%, 20% and 30% decrease with respect to the standard concrete. Keywords: Concrete, Additive, Hydrated Lime, Global Aggregate Method, Optimal Percent Hydrated Lime
