Hydraulic cement concrete is a cement and water paste in which aggregate particles are embedded. Aggregate is granular material such as sand, gravel, crushed stone, blast-furnace slag, and lightweight aggregates that usually occupies approxi-mately 60 to 75% of the volume of concrete. Aggregate properties significantly affect the workability of ...

Crushed concrete is a construction and demolition waste that causes environmental pollution. The reused of crushed concrete as aggregate in new concrete mix has been common practice in many countries. As a result it is a necessary to determine the behavior of crushed aggregate used in concrete production. This project reports the results of an experimental study on the properties of crushed ...

Thus, the current study focuses on the mechanical characterization of waste ceramic wall and floor tiles aggregate concrete. Ceramic wastes sourced from construction and demolition wastes were separated from other debris and crushed using a quarry metal hammer. Ceramic tiles were sieved into fine and coarse aggregates in line with standards.

Crushed Concrete driveways are a much more cost-effective driveway solution compared to gravel driveways, regular concrete driveways, or asphalt driveways. With benefits like the price, sustainability, and the fact that it can never crack and require a repair, crushed concrete is a great driveway option.

All the concrete samples were composed of natural aggregates (crushed granite/gneiss), homogeneous, without organic materials. Both were primarily crushed at the construction site with top-sizes in between 50 and 75 mm (see item 2.1.1 and 2.1.2), and then secondarily crushed in laboratory to obtain RCAs by changing the combination of crusher types.
