Resumen
El objetivo de la tesis es determinar el grado influencia de los principales métodos de diseño en
las propiedades físicas y mecánicas del concreto para el beneficio de la población de la ciudad de
Ica. Los componentes utilizados son los cementos: Tipo HS y Sol Tipo I , el agregado grueso de
la cantera Palomino y el agregado fino del rio Ica, con los que se diseñaron mezclas de prueba,
para una relación agua cemento de 0.50, para los concretos analizados en el laboratorio a través
de los ensayos de consistencia, peso unitario, exudación y ensayos de resistencia a la compresión
a los 7, 14 y 28 días; así como también la determinación de su Módulo de rotura, Módulo de
elasticidad y el % de vacíos. Se realizó los ensayos mencionados anteriormente diseñándose con
los diferentes métodos planteados y se demostró que en los ensayos de consistencia, exudación y
porcentaje de vacíos el método de combinación de agregados resulta mayor que los demás
métodos, y los ensayos de peso unitario, resistencia a la compresión y módulo de elasticidad los
resultados en el método de Füller resulta mayor que en los demás métodos hallados.
Por lo tanto, se llegó a la conclusión que el método Füller es el de mayor seguridad que muestra
en sus resultados obteniéndose una consideración mayor y un costo más elevado para las
pretensiones que se usará por lo que se considera de mayor uso y considerable cumpliendo dentro
de las normas los métodos de combinación y por el método de ACI.
The objective of the thesis is to determine the degree of influence of the main design methods on the physical and mechanical properties of concrete for the benefit of the population of the city of Ica. The components used are the cements: Type HS and Sol Type I, the coarse aggregate from the Palomino quarry and the fine aggregate from the Ica river, with which test mixtures were designed, for a water-cement ratio of 0.50, for the concretes analyzed. in the laboratory through consistency tests, unit weight, exudation and compressive strength tests at 7, 14 and 28 days; as well as the determination of its modulus of rupture, modulus of elasticity and the% of voids. The aforementioned tests were carried out, being designed with the different methods proposed and it was shown that in the tests of consistency, exudation and percentage of voids, the aggregate combination method is greater than the other methods, and the unit weight tests, resistance to corrosion. compression and modulus of elasticity the results in the Füller method are higher than in the other methods found. Therefore, it was concluded that the Füller method is the most secure method that it shows in its results, obtaining a greater consideration and a higher cost for the claims to be used, which is why it is considered to be of greater use and considerable compliance within of the standards the combination methods and by the ACI method.
