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 results showed that the concrete mixture produced with CPCA1 does not meet the minimum requirements established in the Venezuelan standard for use in the elaboration of structural concrete, because among other parameters its resistance to compression it’s below the design value. As for the CPCA1 giving it 15% addition in its own weight meets the requirements, and can be used in the manufacture of concrete structural elements. En los últimos años en Venezuela se ha presentado una crisis en la demanda, comercialización y producción del cemento, material necesario para la construcción, por lo cual se han venido utilizando cementos adicionados sin ningún tipo de regulación. En este trabajo se presenta la caracterización físico-mecánica de tres mezclas de concreto con relación agua/cemento de 0,45 y relación agua/cemento de 0,60 con diferentes tipos de cemento Portland, Tipo I, Tipo CPCA1, y la tercera mezcla corresponde a Tipo CPCA1 retribuyéndole el 15% de adición en su propio peso, desarrollando una mezcla de mejor calidad. Estos concretos se caracterizaron según: asentamiento, tiempo de fraguado, porcentaje de porosidad total, porcentaje de absorción de agua y resistencia mecánica a la compresión. Los resultados demostraron que la mezcla de concreto elaborada con CPCA1 no cumple con los requisitos mínimos establecidos en la norma venezolana para su uso en la elaboración de concreto estructural, ya que entre otros parámetros su resistencia a la compresión está por debajo del valor de diseño. En cuanto al CPCA1 retribuyéndole el 15% de adición en su propio peso cumple con los requisitos establecidos, y puede ser utilizado en la fabricación de elementos estructurales de concreto.
