Utilization of Waste Glasses as Supplementary Cementitious Materials

Wastes of Glass are recognized as pozzolanic material. This study aims to investigate utilization local glass wastes in Sudan supplementary cementitious materials. Two specimens having different colors procured from a source namely Sudanese Emirati and Metal Company (SEGMAL). Then thy ground micro sizes producing two types powders, clear white powder (W-GP) colored (C-GP). The Specimens characterized using tests specified American Society for Testing Materials ASTM C311. These include chemical properties X-ray Fluorescence (XRF), Loss on Ignition (LOI), Insoluble Residue (IR), also physical such fineness, specific gravity, water requirement, strength activity index (SAI). shows that at 7 days W-GP C-GP produced SAI 84% 87% 7-days respectively. values more than the 75% SAI’s requirements C618. Both have outperformed control OPC mix 28 by 108.68% 123.82% GP-W GP-C
