Wastes as aggregate substitution in polymer concrete

The experimental study was effectuated on polymer concrete with wastes as substitution of aggregate. The polymer concrete was prepared with epoxy resin and aggregates in two sorts. Fly ash was added as filler and aggregate sort 0-4 mm was replaced in different dosages by saw dust and chopped PET bottles. The density and compressive strength were experimentally determined. The influence of waste as substitution of aggregate on density, workability and compressive strength was analyzed and compared with a control mix of polymer concrete prepared with natural aggregates and fly ash as filler. The wastes used as aggregate substitution decreased the density of polymer concrete, indicating a lightweight concrete for all mixes. The compressive strength for polymer concrete with wastes as aggregates substitution were closed as values to the control mix.
