Resistência a compressão de concretos com adição de pó de vidro

Abstract

The present work aims to evaluate the technical feasibility of incorporating residues with the addition of glass powder in concrete. The environment has undergone anthropic changes over time, given the high pollution generated from the exploitation of natural resources. The consequences of these actions is the great increase in disposable products. In the city of Macapá, there is a large inadequate deposition of glass waste by resellers. For this reason, the present work aims to evaluate the technical feasibility of incorporating waste with the addition of glass powder in concrete. The dosage method of the Brazilian Association of Portland Cement (ABCP) was applied, and technical tests carried out in accordance with the Brazilian Association of Technical Standards (ABNT). Four strokes were measured, one for reference and three with the addition of glass in the respective percentages 2.5%, 5% and 10% in relation to the cement mass, in which they were mixed in a concrete mixer with a maximum capacity of 140L on average for 5 minutes each stroke. According to the workability analysis of concrete with addition of polymer, there was a loss of concrete slump in the fresh state, but more accentuated for mixtures of 2.5 and 10% when confronted with the reference trace. Therefore, the present study aims to generate an alternative to give an adequate destination to these residues that generate socio-environmental impacts. Based on this assumption, it is recommended for future work that dosages be carried out with smaller proportions of Glass Powder in which they were used in this experiment.
