Abstract

In this paper, mixing of the recycled glass, which possesses a high SiO2 (silicon dioxide) percentage, was utilized to produce a green concrete with remarkable properties. Waste glasses were utilized as cement or fine aggregate partial replacement with various contents (5%, 10%, 15% and 20%) via the weight of cement or fine aggregate. The compressive strength for three ages (7, 14, and 28) days and slump was measured for each concrete mix. Results evinced that the recorded compressive strength increased with the glass content up to10% and then decreased when using glass as replacement of cement, while when using glass as replacement for fine aggregate, the compressive strength decreased initially and then increased with the content of glass. The results of slump test manifested that the concrete workability increased with the content of glass whether the powder of glass employed as cement or fine aggregate replacement.
