Estudo de método de dosagem para concreto convencional

It is known that in most engineering works, concrete is involved. This mixture, which has several parameters and characteristics, differs in its dosage method and materials used. This research describes the results of an exploratory study on the dosing of conventional concrete using the materials available at the Unisul-Pedra Branca material laboratory. Experimental dosages are necessary to find the equilibrium point of workability and ideal cement consumption within the desired strength. A wrong dosage can directly affect the strength of the concrete. In the present work, a pilot trace was used to measure the materials and to adapt the concrete to the parameters recommended by the studied bibliography, and from this a trace is determined rich and poor. With the three determined traits the condition was created to generate the Abrams curve. The Abrams curve allows to establish a relation between the water / cement factor and the compressive strength of the concrete.
