When concrete pours go bad!
Back in the 80’s I was working a job at a remote site that was 45 min. from the closest batch plant. When a truck arrived it immediately poured its load into a pumper truck like those guys in the video were using.
The pumper was fairly new and the guys running it were still learning on the job. Something broke down and they could not get it fixed before the concrete set up all through the system.
Wow, what an expensive mess!
One of the great thrills of my childhood was watching my uncle operate his cement mixer truck — the kind with the rotating drum on the trailer. This was in the 50s. He poured pink concrete especially for me for our family’s back patio!
