AN INVESTIGATION OF THE PERFORMANCE OF PAVING UNITS MADE FROM RECYCLED GLASS WITH A MINERAL ADDITIVE
This paper discusses a project that was undertaken to measure the effect of adding an industrial mineral additive to glass when making glass paving units. Specifically, the mineral additive was added during the fusing process. It had been noted that this additive had the effect of keeping soda lime glass "glassy", instead of becoming dull and hazy in the heating process. The project discovered that the process did leave a smoother surface when the additive was there. Analysis points to the observation that there is a eutectic between soda lime glass and the additive. The final project goal was to construct and test glass unit paving products, which were constructed from glass. Results indicated that a 13-pound per square foot, (1 in. thick) glass paver had greater flexural strength than a 17-pound (1 5/8 in. thick) brick paver and a 24-pound per square foot 92 1/3 in. thick) concrete paver. Also, the glass paving product used less energy to make - 14,900 BTu per square foot - as opposed to 20,100 BTu for clay bricks and the equivalent of 26,750 BTu for concrete pavers. Greenhouse gas emissions were also lower.
