shear behaviour of crushed concrete and bricks
crushed bricks concrete
Shear behaviour of crushed concrete and bricks Two types of crushed concrete, one obtained straight after demolition and the other processed to industry specifications, and one type of crushed were tested. An extensive large-scale shear box test regime was employed to determine the shear strength behaviour of the materials.

The results showed that crushed recycled concrete and masonry rubble can be used to produce good quality road bases. The results indicated that the composition, particle size and degree of compaction have a strong influence on the mechanical properties of recycled materials, but the degree of compaction is the most important influencing factor.
