Waste-to-Energy reclaimed sands as lightweight aggregates for internally cured self-consolidated precast concrete

Waste-to-Energy incinerator plants in the United States provide a sustainable solution for significantly reducing the volume of solid waste and decreasing landfill use. Reclaimed Waste-to-Energy sands have a high absorption capacity and desorb water, which makes them suitable for use in internally cured concrete. This work explores the use of reclaimed sands from the York County Solid Waste Authority (York, PA) in internally cured self-consolidating precast concrete. Concrete mixes are evaluated for strength and durability through compression, split-tension, freeze-thaw, rapid chloride permeability, and autogenous shrinkage. Mixes are also evaluated through Scanning Electron Microscopy analysis. It is found that all of the reclaimed sand mixes have more strength than the control samples. The effect of autogenous shrinkage is seen on internally cured mixes through expansion after set, but a significant reduction in overall autogenous deformation was not observed. In addition, the reclaimed sand mixes showed reduced rapid chloride permeability, but exhibited poor freeze thaw resistance.
