Resumen
El presente trabajo de diploma refleja la evaluación por tres de los métodos de dosificación,
ACI, O´Reilly y Toufar, de la influencia en el comportamiento del hormigón, el uso de los
áridos de la región central de Cuba específicamente de la provincia de Santicti Spíritus. Se
hicieron varias pruebas cambiando el método de dosificación lo que permitió identificar para
cada método la consistencia y la resistencia alcanzadas. Por ello se pudo concluir que al
cambiar el método de dosificación se modifica la cantidad de cada componente de hormigón
y que las propiedades consistencia y resistencia son directamente afectados, principalmente
por la relación a/c derivada de cada método.
The present work of diploma reflects the evaluation by three methods of dosage, ACI, O´Reilly and Toufar, the influence on the behavior of concrete, the use of the aggregates of the central region of Cuba specifically the province of Sancti Spiritus. Several tests were made changing the dosing method, which allowed to identify for each method the consistency and resistance reached. Therefore, it could be concluded that changing the dosing method modifies the quality of each concrete component and that the consistency and resistance properties are directly affected, mainly due to the water/cement ratio derived from each method.
