Strong evidence exists that a combination of mineral admixtures for the concrete and reinforcement with fiber reinforced polymer (FRP) can effectively solve the durability problem associated with the abundance of chloride ions in sea-sand seawater concrete (SSC). Such use of SSC also offers a good opportunity for the incorporation of recycled

Another one of the uses for crushed concrete in your yard is using it to make walls or fences. Taking your crushed concrete and putting it in a gabion (a cage, cylinder, or box filled with rocks, concrete, or sometimes sand and soil) makes a good wall on sloping hillsides. This helps prevent erosion in your yard as well as create a good

But then, I could use local clay soil as the leveling agent–I’d make sure no organic material got in there. i could use sand….and simply deal with the fact that ants often love it. So yeah, that’s probably what I’d do in your case: set larger stones on the edge of the patio.
