Unpopular opinion: A pinch of sugar in the mix is a game changer

I learned this from an old timer on a job site. He told me sugar can slow down the concrete when it's hot out. I didn't believe him until I tried it myself. It gave me more time to get a smooth finish. Now I always have some on hand for tough pours.

Heard that trick before but man, it’s risky. Messed up a whole slab once because it set way uneven. These days I just use a proper retarder from the supply house, way more reliable.
