Blasting abrasive

Black Diamond Blasting Abrasive, which is basically coal slag form off shore drilling, is something I have used in aquatic plantings for a while with good luck. I was wondering if it would be good to use for container soil mixes and if anyone has ever used it or a similar product before. The largest particle size it comes in is 5mm and a 50lb bag is about $7.
