Which term defines the total time spent mixing, transporting, and placing concrete?

• A. Concrete Elapsed Time
• B. Vibrator Use
• C. FDOT Concrete Source
• D. Weep Hole Requirements

Answer: (A)

Concrete Elapsed Time measures the whole duration from the start of mixing through to the completion of placing. It covers mixing, transporting, and placing (and usually finishing), capturing how long the concrete remains workable before it sets. This timing is important because it affects workability, temperature rise, and the risk of early stiffening or cold joints. The other options refer to specific activities (vibrating the concrete), a source of concrete, or drainage requirements, none of which describe the total time span of mixing, transporting, and placing.
