Estudio de las propiedades físico-mecánicas del concreto con incorporación de vidrio molido y análisis comparativo a partir de concreto con fibra de acero y concreto convencional

Abstract

Through this research work, the behavior of concrete is established with the incorporation of different percentages of ground glass (3%, 5%, 8%) as a replacement for fine aggregates, designing twenty-seven (27) cylinders distributed equally for each percentage to which each respective dose of this material was added. Likewise, nine (9) conventional concrete cylinders and nine (9) steel fiber cylinders were designed, based on which the proposed comparative analysis was carried out, in order to establish their structural and economic viability.

It was necessary to carry out crushing tests with the use of the angel’s machine, granulometric analysis tests and finally compression tests for the cylinders, considering the different failure ages established for each one, and whose results allowed determining the resistance to compression and modulus of elasticity of each sample, to later determine the structural and economic viability of the studied material.

The results obtained showed the economic and structural viability represented by the use of ground glass as a replacement for a certain percentage (3%) of fine aggregate in the concrete mixtures by presenting more than appropriate values in its resistance throughout the development of the research project. , in addition to reducing the cost of production, taking into account that glass is a recyclable material whose properties are similar to those of fine aggregate when crushed and sieved for this purpose. The results with the greatest analysis were those presented after fifty-six (56) days when considering it the appropriate time for the correct homogenization of the mixture based on the information that was initially had on the physical-mechanical properties of the glass, this being the age at which the modulus of elasticity and Poisson's ratio were calculated, obtaining acceptable results and based on which the aforementioned was defined.
