VARIATION OF THE STRENGTH OF CONCRETE ACCORDING TO THE TYPE OF ROCK USED AS COARSE AGGREGATE

Abstract

For the concrete to be a material with superior performance on the construction process and for the efforts in which will be submitted during the lifetime of a building, the material that is to be quality assured by normative criteria on materials. This work described on the concrete material, and its constituents. In addition, trace obtained a rational concrete with two different types of coarse aggregate used in the city steps. During the development work it was possible to make a concrete dosing with traces obtained and compared with two traits whose behaviors were known. At the end, you can see the best concrete performance in fresh and hardened state when using the Diabase.
