Green Composite Concrete Incorporating with Non-Biodegradable Wastes

This research studied the properties of the green composite concrete for paving blocks comprised of the non-biodegradable wastes of PET bottle flake (15-35 wt%), metalized plastic film from food packaging (0-5 wt%), colored glass powder (5-15 wt%), and ground tire rubber (5-20 wt%) as low cost and ecofriendly reinforced materials. The various concentrations of those wastes in the concrete can be grouped into 14 compositions. The properties of the composite paving blocks were compared to those of standard concrete in terms of density moisture absorption, water absorption, and compressive strength. The results showed that the standard paving blocks had better properties than those of composite paving blocks. The combination of colored glass powder in the concrete can enhance all properties of the concrete block; moreover, the insertion of scrap tires can improve moisture absorption property. However, the addition of metalized plastic, and plastic bottle wastes induced the void inside the concrete decreasing the properties of the concrete.
