In recent years Venezuela has presented a crisis on the demand, commercialization and production of cement, the material needed for construction, therefor additive cements are being used without any type of regulations. This work presents the physical-mechanical characterization of three concrete mixtures with water / cement ratio of 0.45 and water / cement ratio of 0.60 with different types of Portland cement, Type I, Type CPCA1,and the third mixture corresponds to Type CPCA1 Rewarding it with a 15% addition in his own weight, developing a mixture of better quality. These concretes were characterized by: settling, setting time, percentage of total porosity, percentage of water absorption and mechanical resistance to compression. The result...
