摘要

The feasibility of using ground waste glass as cementitious material for concrete was investigated in this paper. The non-recyclable fluorescent lamp glass was collected from the recycling process of mercury containing lamps. The waste glass was ground and sieved to the size smaller than 150 μm, 75 μm and 38 μm, respectively, to study the size effect on the pozzolanic behavior. With 30% cement replaced by ground glass, the normal strength concrete gained strength activity index 91%, 84%, 96% and 108% at 3, 7, 28 and 90 days respectively, exceeding 75% at all ages. The pozzolanic activity of ground glass was examined through lime tests. The glass having a particle size finer than 38 μm exhibited a satisfactory pozzolanic reaction. The expansion of glass concrete in highly alkaline solution was also tested. It was observed that small glass particle size led to a high reactivity with lime, a high compressive strength and a low expansion in concrete. While the glass concrete was directly comparable to fly ash concrete, it had difficulty to compete with concrete having same amount of silica fume.
