Lime-silica products based on waste packaging glass

Waste packaging glass with different chemical compositions were used to prepare lime-silicate products, a form of eco-friendly building materials. The percentages of glass, occurring in three colours: colourless, green and brown, were 33, 66 and 100 per cent by weight of quartz sand, which, along with lime, is the main component of silicate products. Compressive strength, bulk density and water adsorption were tested on autoclaved cylindrical specimens with a height and diameter of 25 mm. The results show that as the waste glass content of the autoclaved samples increases, the compressive strength and water adsorption increase, at the same time, the bulk density decreases. The chemical composition that determines the colour of the glass shows differences in the physical and chemical characteristics obtained.
