STUDY OF EXCHANGE OF CONVENTIONAL AGGREGATES FOR MILLED GLASS IN NON-STRUCTURAL CONCRETE BLOCKS

Abstract

This article presents a comparison study on the exchange of conventional aggregate for ground glass in non-structural concrete blocks, in order to investigate the possible benefits of replacing some percentages of ground glass with crushed glass. The work aims to produce blocks using ground glass in its composition, in three different proportions, namely: ten, twenty and thirty percent by mass, with the intention of comparing its properties, such as weight, strength and weight. production cost, with conventional concrete blocks, in addition to subjecting them to tests to assess their quality. The methodology shows how the blocks were produced, reporting the details of the line and the steps that followed until the end of its cure, as well as the systems used for the tests. After dimensional and compressive strength evaluations, it was concluded that the addition of ground glass in any of the three proportions kept the blocks within the parameters of Brazilian standards, but the proportion of 20% (twenty percent) was the best among those tested.
