I�m building a pathway using pieces of broken concrete and to fill the gaps instead of using polymeric sand I have leftover unstablized DG from another project that I wanted to use. I expect the gap thicknesses to be between 1"-3". Someone from a stoneyard mentioned you can mix DG with white cement to fill in gaps with. Has anyone ever mixed DG with cement for this purpose? What were the proportions? This pathway will get a lot of foot traffic so I want the pieces of broken concrete and the gaps between them to be as level as possible so I thought DG mixed with some sort of stabilizer will give it extra support instead of crumbling which I've noticed with pathways I've done with DG only.
