The Influence of Waste Glass Slurry on the Properties of Concrete

The grinding of glass waste chips in a wet environment for 120 minutes gives possibility to obtain particles finer in size in comparison to glass waste chips ground in dry environment. The particle distribution analysis showed that borosilicate glass lamp waste slurry has particle size in the range of 0.713 μm to 8.088 μm, fluorescent lamp glass waste slurry - from 2.473 μm to 20.088 μm, amber glass cullet slurry - from 1.435 μm to 21.118 μm, green glass cullet slurry - from 0.903 μm to 23.125 μm, flint glass cullet slurry - from 1.511 μm to 8.932 μm. The obtained waste glass slurries show pozzolanic characteristics and using of them as a cement component in concrete might be a solution for CO2 and accumulated landfilled glass wastes reduction. Application of waste glass slurries in concrete has a positive effect on workability of concrete mixtures and improves considerably mechanical properties of concrete at early ages. The alkali-silica reactivity (ASR) tests results indicate that the presence of finely ground waste glass in wet environment has a relatively small influence on ASR expansion
