Análisis y diferenciación de la caracterización y las propiedades mecánicas de flexión y compresión para un hormigón de 21 y 28 MPa con agregados pétreos de río y montaña

Abstract

This article is based on the investigation of stone aggregates of different origins. The physical and mechanical characterization of the stone aggregates significantly influence the construction of civil works, for this reason it has been decided to develop this research that deepens issues that are related to each other. The methodology of this research is experimental and was developed through different tests that were carried out in the laboratory to determine the physical characteristics such as: granulometry, density, specific weight, unit mass, percentage of voids, abrasion, humidity and organic content; These tests were carried out as well as in the fine aggregates and coarse aggregates as appropriate for materials from rivers and to be able to differentiate them with the physical characteristics of materials from mountains. Through these results it was possible to determine a dosage for a concrete of 21 and 28 MPA and thus be able to characterize the mechanical properties of each material such as: resistance to compression, modulus of elasticity and flexion. The results of this article will be exposed throughout this document.
