If you use concrete it's still the dirt around the concrete that supports the fence; you have just added 30 pounds of concrete to the bottom of it. If your soil has good percolation and water can settle away quickly (as I do where I am in Wisconsin) I prefer to use sand most of the way up and bout 4 - 6 inches of dirt on top of the sand.

When the content of manufactured sands dust in concrete …

Replacement of stone dust (SD) by ceramic waste (CW) leads to the increment in the compressive strength up to the optimum value of replacement as 20%. At the point of optimum replacement of stone dust with ceramic waste compressive strength is an increment of a maximum of 16.30%. But the workability of the concrete is …

Landscaping. 1. Sub-base for Patios and Pathways: Grano dust provides a stable, level foundation essential for laying patios and creating smooth, even pathways. 2. Grano Dust for Artificial Grass: It's used as a top dressing over the base layer, enhancing stability and appearance of artificial grass. 3.
