The specified strength should be achieved at
Concrete can accumulate and harden in dozens of joints and crevices in air meters, damaging petcocks, bleeder and pressure valves, clamps, and threads just by neglecting a quick cleaning while the concrete is fresh. Concrete accumulating in the measuring bowl can change calibration values, throwing off test results by a significant amount.
