  1. my dad idea of summer vacation was to drag me out to his work crew. started when I was 11 or 12
    I think. pouring and later mixing concrete and cement for block laying, and on a good day brick work. bricks are a lot lighter than 12 semi solid blocks !
    did that until I went into the army. by then, I was 6 foot 2 and 190 solid muscle.
    there, I found out I was in better shape than my drill sgt. where. the crew had saying. if you make the first week, you make the summer. hard, hot work. way better than any gym to get in shape though. lots of guys never lasted the first week though. paid well for the time too.
    looking back on it, I think it was the best thing my dad did for me. learned how to work, got strong as hell, and learned how to stand alongside men and hold my own. all the things that made life a bit easier for me later on in life. it is a good thing !

  2. My summer job was working around the gravel pit.
    My dad's, once he retired, was to do a survey of sand and gravel deposits in the western US for the Rock Products Association. Interestingly, we are running short of commercially viable deposits. The pit I once drove a pickup truck in is now below the water table and they mine with a dredge.

  3. Concrete is fascinating stuff and can be surprisingly technical.

    Water is a chemical ingredient, and too much or too little water will ruin it. Drivers are famous for adding extra water during truck washdown. Just like in the video.

    Residential concrete is slop. It runs down the chute just like in the video. 2500 psi if you're lucky. No way they'd get a 5 inch slump test from that.
