I’m restoring an old house in New Orleans and I’ve torn out a bunch of old horse hair plaster that was beyond saving. Since it is mostly lime and sand, could I mix it with sand and use it in a concrete mix? I plan to pour a floor in part of the house that will be used as a welding studio so it wouldn’t be anything structural. I just need a relatively flat floor that won’t catch fire. I have alot of old concrete chunks from a sidewalk I tore up. How would I use these as fill? Thanks for your advice!
