A Study on Engineering Properties of Self-Compacting Concrete Containing Waste LCD Glass

Article Preview

Abstract:

This study investigates self-compacting glass concrete(SCGC), which was used at water-to-binder ratios (w/b) of 0.28, with four kinds of glass sand replaced at various volume replacement ratios (0%, 10%, 20%, and 30%). Fly ash, blast furnace slag and superplasticizer were also added to research the engineering properties of concrete. With increasing amounts of replacement up to 30%, results show that: (1) slump flow and V-funnel time are increased; (2) 340 mm is passed at 0min, and the filling level is elevated at 45 min; (3) the compressive strength of SCGC aged 28 days at various replacement ratios rises up to 60 MPa. The ultrasonic pulse velocity and electrical resistance are also enhanced with increasing age and replacement. After 56 days, the electric resistivity is higher than 20 KΩ-cm, and the shrinkage of SCGC falls within 0.2%. This study suggests than SCGC has superior engineering properties. A mechanism for LCD optical waste glass usage can be established to achieve industrial waste minimization, resource recycling, and economic security
