If you are only using the raceway as a duct you can use "cables" in
the same pipe. For exaample you can put a 3/4" piece of PVC conduit in
the slab and pull a Romex and a Cat 5 through it as long as you don't
break into the Romex until it gets separated from the Cat 5.
Cable jackets are separation

It doesn't keep you from getting noise in the circuits. You should
never run signal cables in the same race way with power circuits. You
may get away with it for a while, but you never know when it will fail.
