Caracterización de las propiedades físicas y químicas de los agregados finos y gruesos con mayor demanda en la ciudad de Tunja

Abstract

This study is based on the need to characterize the thin and thick aggregations used for the making of concrete, and selected of the principal quarries that give the city of Tunja. As intention is tried to realize a study of characterization to the aggregations used as base of the concrete one, to 5 quarries of thin and thick aggregation that expire with the rules and that have major demand in the city of Tunja, the chosen previous thing with base in the work realized by Ibáñez, Jhon and Núñez, Leonardo (“ 20 quarries of thin and thick aggregation with major demand in the city of Tunja with his respective analyses of quality to each of them ”), I hold to the Colombian norms for the characterization of aggregations proposal. In this sense NTC 176 takes the established as the ICONTEC with the essays, NTC 3674, NTC 98, NTC 77, NTC 1776, realizing them to 5 quarries of gravel and sand, acquiring the information of the essays, there is proceeded to select 1 sample of the quarry of gravel and 1 of sand with the most ideal results, and in turn 1 sample of the quarry of gravel and 1 of sand with not such good results, that they are inside the status established by the chosen essays of the ICONTEC, later the chemical composition decides with the skill of characterization for spectroscopy of fluorescence of x-rays, in such a way that the methodology allows, from this chemical composition, to explain the response of the aggregation to the chosen essays established by the ICONTEC.
