Five different recovered glass samples were evaluated as additions to a commercial brick mix in amounts of 10, 15, and 20 wt pct. Based on the results, a large-scale plant test run of full-size brick containing 0, 10, and 15 wt minus 100-mesh ground glass was carried out. It was determined that the cost of crushing or grinding the waste glass amounted to about $3.85 Per megagram and that a 10 wt pct addition of the ground glass reduced the firing temperature of the building brick about 40 deg.C. Scumming, due to sulfates present in the ground glass, could be a problem and may require the addition of barium carbonate to a brick mix.
