CONCRETE TECH FINAL EXAM QUESTIONS
WITH CORRECT ANSWERS 2026-2027
What are the two common types of concrete batch plants? - CORRECT ANSWER -
dry batch plant and central batch plant
What is the difference between dry batch plants and central batch plants? - CORRECT ANSWER -
dry batch mixes concrete in the truck and central batch uses a central mixer.
What are the different equipment within a batch plant? - CORRECT ANSWER -
cement silo, fly ash silo, aggregate bins, batch house, water tank, admixture tanks
T/F: The common central batch sequence of typical concrete mixtures has water continuously be
ing batched throughout the batching sequence. - CORRECT ANSWER -True
T/F: The common dry batch sequence of typical concrete mixtures has headwater of roughly 2/3
and tailwater of roughly 1/3. - CORRECT ANSWER -True
T/F: Materials for ready mixed concrete is batching by only volume. - CORRECT ANSWER -False
T/F: Liquid admixtures are batched by volume in fluid ounces. - CORRECT ANSWER -True
T/F: Powdered admixtures are batched by volume in fluid ounces. - CORRECT ANSWER -False
What is the place that monitors and controls the operation of a concrete batch plant? -
CORRECT ANSWER -batch house
, Concrete can be commonly transported from the batch plant to the jobsite using ?-
CORRECT ANSWER -Ready-mix truck
How is the rate of discharge controlled on a ready-mixEdrum truck? - CORRECT ANSWER -
rate of revolutions
What are the discharge time and revolution limits per ASTM C94? - CORRECT ANSWER -
1.5 hours, no revolution limit
ASTM C94 requires that every truck mixer shall have prominently displayed a plate showing: -
CORRECT ANSWER -gross volume of drum
capacity of drum in terms of volume of mixed concrete
minimum and maximum speeds of rotation of the drum
When ordering concrete, the common practice has been to order of concrete calculated fr
om form dimensions during construction. - CORRECT ANSWER -
3 to 10 %Emore than the exact calculated amount
Purchasers should estimate about more concrete than the volume calculated from form di
mensions to allow for contingencies (waste and spillage, over-
excavation, spreading forms, loss of air, or settlement) duringEconstruction. - CORRECT ANSWER -
order exactly what the mathematical calculation is to fill the form(s)
What is a batch ticket? - CORRECT ANSWER -
document containing the weights of the material batched
What is a delivery ticket? - CORRECT ANSWER -the purchasing receipt of the concrete
