[@claudekim7876]

[@femiadebayo4910]

Why does he place the rod next to the cylinder

[@gabrielbattaglia7758]

Gives him an idea on how far to penetrate the previous layer

[@karleggman5414]

Molds used for test specimens should be placed on a level, rigid surface, free of vibration and other disturbances! A flexible table or tailgate of a truck are not acceptable places to mold test cylinders per ASTM C31.

no one really cares tho. some sites dont even have the curing box anywhere near the concrete truck. im not carrying 6 cylinders 200 meteres. also you have to cast real fast else you gonna miss all ur next sites XD
