Determinación de las propiedades mecánicas de concretos elaborados a partir de las arenas provenientes del río Guatiquía utilizados para la construcción en la ciudad Villavicencio – Meta.

Abstract

One of the main water sources surrounding the city of Villavicencio is the Guatiquía River, which is a great source of exploitation of stone materials that can be used as construction materials, such as crushed for base, sub base, thick and fine aggregate. This investigation took as object of study the fine aggregate (sand), for the design and manufacture of a structural concrete, having like purpose, to study its mechanical behavior thus, to verify which is its more suitable use.

To give veracity to the investigation, it was made under the minimum parameters demanded by [1]. Once the fine material was obtained, a physical-chemical characterization of the aggregate was made, obtaining two tests that did not comply with the minimum acceptable value.

The proposed concrete mixture design was of a resistance of 21 Mpa, later, the tests that would determine the mechanical properties of the concrete were applied, such as the resistance to the compression, resistance to the flexion and the elasticity module, nevertheless, the use of the fine aggregate of the Guatiquía River serves for a use in non-structural concrete such as screed concrete, for sardinels, platforms, ceramics, among others. In addition, it was found to be highly applicable as a masonry filler mortar according to the criteria of [2].
