Crushed concrete is a very good substrate for a slab. The key is to not have chunks so large that air pockets are created. Maybe bring in a layer of sand to fill the voids and level things a bit. A water rinse will help bring air out and compact the material. Share. Improve this answer.
A "crusher run" material, usually graded from 38 mm to 50 mm (1-1/2 in. to 2 in.) down to rock dust, is suitable. Following compaction, the surface can be choked off with a fine-grade material to separate the vapor ... concrete slabs also results in flexural crack formation and possi-

This has also been observed in slabs with shear reinforcement recently tested by the authors and presenting a failure due to crushing of concrete struts (Figure 2). The origin of this delamination can be explained by the tangential strains developing at the column vicinity as a function of the rotation of the slab ( Equation 1 ).
Concrete from many different applications such as old concrete structures, sidewalks, building slabs, foundations, curbs, and more can be recycled into RCA. How is Concrete Recycled?
