Crushed slag alternate to gravel.
Currently crushed slag can be used in place of gravel when making concrete slabs. It would be nice to use crushed slag as an alternative to gravel in other recipes like Manufactured Sand, Filter Media, Dirt, and in the building of railroads.

Railroads sounds ok, but in the other cases you do not want to use slag. It's full of trace metals and is prone to leaching them into water. Frankly we a shouldn't use it for landfill but people have been doing that for some time irl despite the hazards. I think manufactured sand is only used in concrete, so that's a maybe. -

Rolling StenSlag is combination of many materials and is in fact waste product. It doesn't matter when entrapped in concrete, but it cannot be processed into fine grinded sand working as one definitelly not used as filter media, because it is itself toxic waste. It cannot be even used in concrete instead of man. sand as that needs some mechanical/chemical properties for concrete to be strong and lasting enough.
