That is actually mortar, used to lay block and brick, rather than concrete. There is no course aggregate in it.

My brother said they used a roto tiller when he was working on a 175,000 sq ft marble job at a mall back in the day.

That's a great idea. The consistency is probably not perfect, but for most pours it's probably fine.

The consistency is much drier than a concrete mix. It is called dry pack, pick up a hand full and squeeze it should compress to a firm ball, drop it to a hard surface it should break apart to a loose mix.
Back in the late 90's my cousin and I did a boys school job, a little over 8,000 sq.ft. on "Mud",
we used about 40 tons of sand and cement. His brother did a power plant floor in Idaho 64,000 Sq.ft.!
On the school job I had a union helper working with us, Nicknamed Skippy he would pile sand and cement on the floor till about 6' high then mix it. He would say it almost mixes itself!
