Compressibilidade de misturas de um solo argiloso com resíduo de vidro

Abstract

In Brazil, solid waste is one of the main problems of urban planning and public management in the country. About 160,000 tons of solid waste are produced daily, of which 2.34% are glass, and although we have the potential to recycle up to 40% of all material that is generated, only 13% receive right treatment. Research points to the feasibility of applying this residue in cementitious materials and mixtures with soils. Likewise, this work aims to contribute to the knowledge about geotechnical properties of mixtures of glass waste in soils through the analysis of laboratory tests. Two different proportions by mass of the mixture of glass waste and a lateritic clayey soil were studied, namely 5% and 10%. Double edometric tests were carried out both with the mixtures and with the virgin soil to evaluate the compressibility. Filter paper test was performed for the 10% mixture in order to aid the interpretation of the results. For a more complete evaluation of the characteristics of the mixtures, results from previous research were used, namely: granulometric curve, grain specific mass, consistency limits, compaction, and soil water retention curve. It was noted in the results that the presence of 5 and 10% of residue addition to the soil practically did not affect the results of compaction, water retention curve and soil compressibility, although results from the literature show an increase in the resistance of soil-soil mixtures glass residue.
