| Description: | Miscellaneous paper Abstract: The use of crushed waste concrete as concrete aggregate began in Europe at the end of World War II. Depletion of supplies of high-grade conventional aggregates in certain regions, the need for better methods of solid-waste disposal, and energy conservation have contributed to a new interest in this technology. Both earlier and recent research indicate that crushed old concrete will have higher absorption and yield concrete of lower strength at equal water-cement ratio and slump than concrete ma.de with similar aggregate not previously used. Where the original concrete was of low resistance to frost action, concrete made using it as aggregate had improved frost resistance. It is concluded that recycling concrete for use as aggregate in new concrete is feasible and may become routine. |
