as filler to reduce the concrete volume needed, I mean.
I am talking about a slab floor construction common or standard in Southern Cal newer homes, not concrete foundation with floor joists.
There are a lot of give away broken concrete pieces and river rock. Can I use them to fill the concrete slab?
My thinking is that it is OK as long as the pieces and river rock are small, say 3" thick and 4-5" in other dimensions, or smaller, and using them in the middle non-weight bearing section of the slab.
The weight bearing sections (perimeter) of the concrete slab will not have such filler.
Any opinion. I found it hard to believe that such filler will "sink" later once the slab has cured.
Also I plan to add such (the smallest) pieces 3" or smaller into the cement mixer and not just pour concrete mix over the filler pieces. I think this way the fillers with adhere to the concrete better. Will the mixer take it without falling apart? Mine is a small 3.25 cu feet mixer.
Thanks
