Análisis de agregados pétreos para concreto en las principales canteras de la parte baja de la provincia de El Oro.

Abstract

The present titling work consists of the analysis of the stone materials that we can find in the main quarries of the lower part of the province of El Oro, focusing mainly on the materials that are used for the elaboration of concrete, which are sand as fine aggregate and gravel as coarse aggregate. For this, samples were taken from the previously selected quarries and laboratory tests were carried out such as: densities, loose and rodded volumetric weights, granulometry, wear and impurities control, in order to obtain the main characteristics of said materials and to be able to carry out an analysis. of the quality of existing stone in the province. The results obtained were compared with each other with the samples from each quarry to show which are the best materials with the best performance, in addition to verifying that the stone materials meet the quality standards, a comparison of the minimum requirements and specifications that they must have was made. aggregates for concrete based on the ASTM-C33 and NTE INEN-872 standards.
