Abstract:
Glass is considered among the most environmental recycled wastes. One of its important contributions is concrete production as an Echo-Friendly-Concrete. This research focuses on the effects of particle size and content of recycled glass powder on durability with regard to resistance to freezing and thawing of high-performance concrete. White waste glass bottles finely crushed are used as a partial replacement for fine aggregate with various proportions (15%, 20%, 25% and 30%) and two particle sizes of waste glass powder were selected for each replacement ratio including size ranges of 0�315μm (HPCGA) and 0.315�1.25mm (HPCGB). Specimens with silica fume were made for comparison. This study aims to determine the level of waste glass powder replacement resulting in optimal resistance to freeze-thaw. Experimental tests deals with the exposure of specimens to periodic freezing and thawing. Sets are tested focusing on measurement of the relative dynamic modulus and change in mass and the compressive strength at 7, 28 and 90 day. Up to 30% of waste glass content and particle size less than 300 μm the findings seems fairly satisfactory compared than that of silica fume. The durability factor was only 98% indicating good freeze- thaw resistance.
