Influence of the addition of glass from long neck bottles in the properties of the reactive powder concrete

This work presents an economical, technical, and environmentally correct solution for the disposal of long neck bottles (which cannot be bottled more than once), by replacing fine aggregates (sand) with residue ground glass from in production reactive powder concrete (RCP). Using a reference formulation RCP containing natural sand, this raw material was replaced 12.5, 25, 50, 75 100 wt.% residues, evaluating physical mechanical properties specimens at ages 7, 14, 28 days. The characterized X-ray Fluorescence DSC tests, indicating that it is typical sodo-calcium glass, transition temperature equals to 560C. Grain size distribution optical microscopy assays sand indicated comminution let acquisition granulometry similar but very different geometries roughness. replacement 100% presented best results properties, reaching 85% strength value composition, about 96MPa; composition also lowest water absorption (3.94%) void index (9.33%) among all compositions. potentially feasible, promoting destination construction sector, bringing reduction environmental impact, generating within technical standards required norm.
