Hmmm, early version of the compressed air system?!
in '88 I had a conduit going from phone room to under concrete floor to center of room in new construction, BLOCKED. Fish tape both ways, fish tape with a hunk of doublejack chain to try to snag with tape from other end. No joy. Electrician brings in a compressed air bottle w/hose and adapter and sticks it on phone room end. His partner holds a piece of sheetrock over the floorbox 2-3 feet above floor. POOF, a load of concrete chunks, wood pieces, and assorted other garbage. Sparky said, "If you don't hold something over the box, there WILL be a flourescent fixture over the the box, and it WILL be damaged."

My experience comes courtesy of union sparkies sabotaging our conduit runs by stuffing rocks and soil down them.

I heard if you cut the top off a can of expanding foam you can use a duct rod to push it in to the first bend.

I am going to share a conduit experience that will "blow your mind".
Back in 68-69 time frame I was installing phones in a dept store. Keep in mind this was back in the day when it was common that jobs required the electrical contractor to provide a conduit for each phone.
Well, one of the conduits was stopped up about 75 feet into the run of a 150 foot conduit. I tried to force the fish tape but to no avail. I went to the electrician and told him his conduit was clogged. He poked around with it a few minutes and finally let loose with a few expletives. He then went to his truck and came back with a blasting cap and a roll of wire. He connected the blasting cap to the wire, taped it to the fish tape and inserted it into the conduit until it reached the blockage. He then set off the blasting cap and the blockage (pieces of concrete) came blowing out the other end. We then vacuumed the conduit to remove the residue and all was good.
When he inserted the blasting cap into the conduit I thought for sure we were going to have a blowout in the middle of the floor!
Bill Yeah, the cap alone won't blow a hole in the floor,....... now if he had mixed a few bags of ammonium nitrate and a few gallon of diesel fuel to the mix.... You would proably need more than the floor fixed. LOL!

Conduit of yesteryear had the consistency of HY-80! Today's stuff is made out of Kia's and Yugo's! Excellent pipe job, too...
