Concrete recycling - Wikipedia
Concrete recycling is the use of rubble from demolished concrete structures. Recycling is cheaper and more ecological than trucking rubble to a landfill. Crushed rubble can be used for road gravel, revetments, retaining walls, landscaping gravel, or raw material for new concrete. Large pieces can be used as bricks or slabs, or incorporated with new concrete into structures, a materi

Effect of curing methods on the strength of interlocking paving blocks
The resulting performance of concrete mixtures is dependent on its composition such as the binder, aggregate, water content, etc (Atoyebi et al., Citation 2018a; Gana et al., Citation 2020; Panda Ghosh, Citation 2002). One of the important low strength concrete composite used mostly in developing countries is interlocking paving blocks (IPB).
