1. What is the primary function of a concrete pump?
A. To mix the concrete at the jobsite
B. To transport and place concrete
C. To add water to the concrete
D. To break up hardened concrete
Rationale: A concrete pump is designed to move freshly mixed concrete
from the mixer to the placement location, especially where access is
limited.
2. What type of concrete pump uses a flexible hose and is often used for
smaller jobs?
A. Boom pump
B. Line pump
,C. Trailer pump
D. Tower pump
Rationale: Line pumps use hoses and are best suited for smaller-scale
concrete placement.
3. What should be done before starting a concrete pump for the first
time each day?
A. Add more concrete
B. Perform a pre-operational inspection
C. Check the slump of the concrete
D. Drain the hydraulic fluid
Rationale: A daily pre-operational inspection ensures the safety and
readiness of the pump.
4. What can happen if the pump line is not primed before operation?
A. The concrete will be too wet
B. Air bubbles will form in the concrete
C. The pump may clog
D. The concrete will be over-vibrated
Rationale: Priming helps lubricate the pipe interior and prevent blockages.
5. What is the correct slump range for concrete used in most pumping
operations?
A. 1–2 inches
B. 2–3 inches
,C. 4–6 inches
D. 8–10 inches
Rationale: A slump of 4–6 inches is generally ideal for pumpability without
segregation.
6. Which of the following is a sign of a blocked line during pumping?
A. Decrease in line pressure
B. Sudden increase in line pressure
C. Slump increase
D. Pump cycles speed up
Rationale: A spike in pressure often indicates a blockage in the delivery
line.
7. What safety measure must be taken when operating a concrete boom
pump near power lines?
A. Move power lines
B. Maintain required clearance from the lines
C. Ground the boom
D. Use wooden boom sections
Rationale: OSHA requires a minimum clearance (typically 20 feet) from
energized power lines.
8. Why should elbows be minimized in concrete pumping lines?
A. They are expensive
B. They are hard to clean
, C. They increase wear and chance of blockage
D. They weaken the pump
Rationale: Elbows cause friction and turbulence, which can lead to
blockage and wear.
9. What material is most commonly used for pump lines?
A. PVC
B. Aluminum
C. Steel
D. Rubber
Rationale: Steel pipes are strong and durable, making them ideal for
concrete pumping.
10. What does S.T.A.M.P stand for in pump safety?
A. Standard Time and Manual Practice
B. Stop, Think, Act, Monitor, Proceed
C. Safety Training and Maintenance Program
D. Safe Techniques and Methods Protocol
Rationale: "Stop, Think, Act, Monitor, Proceed" is a basic safety reminder
for concrete pump operations.
11. Which component of a concrete pump ensures the pumping
action?
A. Sprocket
B. Rotary motor
