Diseños alternativos sostenibles para el hormigón hidráulico con la utilización de vidrio molido como parte de agregado fino

Abstract

This project focuses on the development of sustainable hydraulic concretes, with the incorporation of recycled aggregate in partial replacement of fine aggregate. The recycled material to be incorporated into the mix is ground glass from the collection and recycling of bottles for daily use, which can be found in large quantities. The materials used for the production of concretes were properly characterized, fulfilling the necessary features required for the ASTM C33 standard, for use in concrete mixes. Based on the results obtained in the characterization, a standard dosage was designed to be used as a reference mixture and thus be able to quantify and qualify the performance of the other mixtures. The main objective of the project was to analyze the feasibility and sustainability of hydraulic concretes with the use of ground glass as part of the fine aggregate, for which the elaboration of 10 types of mixtures with different percentages of ground glass and counting with 9 specimens in each mix. Destructive tests were used in each of the concrete elements, as well as the use of calculating and qualifying computational tools to obtain certifications based on their sustainability and gas emissions to the environment. Destructive tests were carried out to obtain the resistance to simple compression and to indirect traction. While the qualifying computational tools were Greenroads and LEED and the calculating tool was PaLATE. The curing times considered were 7, 14 and 28 days
