I ended up sweeping it off because I didn't like the looks of it and didn't want to track into my house.
I think I'll just dump it over the embankment in my back yard from now on.
Not sure what's wrong with your ash. Mine is the best traction agent ever. We always keep a barrel of it handy. Wet shoes come off at the door in all seasons here, so tracking it in the house is not an issue.
Most of our ash for the past few years has been used to build up my brother-in-law's unpaved driveway. Before that we had an unpaved driveway, and used the ash for that purpose ourselves.
We now have a paved driveway in pretty marginal condition. My favorite use of coal ash has been in a custom "flowable cinder block" pavement patching compound. The right mix of portland cement, bottom ash, fly ash, plasticizer and tint has the working consistency of pudding and can be screeded singlehandedly by an old guy with a 2x4. And it hardens like concrete and has withstood all forms of weather extremes and lots of traffic. For under $80 in materials I generated and installed a couple of cubic yards of color-matched patches, instead of paying 15x that much to the low-bid paving contractor.
It's not perfect but is a giant improvement over the mess that was there.
