Bagged lime is rarely used in this area so it may have calcined in the bag sitting in the warehouse. So I'm making my own slaked lime and mixing it with coal slag aggregate which is ferro-silicate glass ground up into a coarse sand consistency, and sharp granite gravel. The walkway should be more durable than the adjacent portland concrete walkway. Part of the new slab is going to be covered by pots full of culinary and medicinal herbs. The soil dug up from the slab location is going to become cob for building kilns. I'm building 2 kilns and a bread oven from cob.
