Recycled Aggregates - Portland Cement Association

In general, applications without any processing include: 1. many types of general bulk fills 2. bank protection 3. base or fill for drainage structures 4. road construction 5. noise barriers and embankments Most of the unprocessed crushed concrete aggregate is sold as 1½ inches or 2 inches fraction for pavement subbases. After removal of contaminants through selective demolition, screening, and /or air separation and size reduction in a crusher to aggregate sizes, crushed concrete can be used as

Casting Concrete With Recycled Plastic Aggregate : 5 Steps

Casting Concrete With Recycled Plastic Aggregate: One of the biggest challenges with recycling is plastic. There's not much of a market for scrap plastic, so the profit margins on processing and reselling it are slim. When oil prices dip, it becomes cheaper to make new plastic than to recycle exist…
