Preview Questions Steel Fixer | Role Specific Skill

Question 1: What does a high rebound reading in a rebound hammer test typically indicate?

Which action should you take?

Choose only one option

High corrosion resistance of the steel reinforcement

High compressive strength of the concrete surrounding the steel

High ductility of the steel reinforcement

Low quality of concrete bonding

Question 2: How should steel bars be positioned in a slab to achieve the optimum load distribution?

Which action should you take?

Choose only one option

Reinforcement should only be placed at the top layer for cost-saving

Reinforcement should be placed in both directions, typically top and bottom, as per the design

Place reinforcement only in the middle of the slab

Place all bars at one end of the slab to ensure uniform strength

Question 3: For a non-destructive test (NDT) on steel reinforcements, which method can be used to evaluate welding integrity?

Which action should you take?

Choose only one option

Visual inspection

Ultrasonic testing

Impact testing

Radiographic testing

Question 4: What is the ideal outcome of a structural integrity test on steel reinforcement bars?

Which action should you take?

Choose only one option

The steel bars should exhibit uniform bonding with concrete

The steel bars should pass load-bearing tests

The steel should show minimal signs of corrosion

The steel bars should bend without breaking

Question 5: Which safety precaution is essential when using cutting tools?

Which action should you take?

Choose only one option

Cut steel at the specified angle to avoid stress on the tool

Ensure all tools are in good condition and free from defects

Only use cutting tools on reinforced concrete

Wear no PPE while using cutting tools

Question 6: When conducting a bend test on steel reinforcement bars, which factor is most critical in ensuring accurate results?

Which action should you take?

Choose only one option

The temperature of the steel bars during bending

The type of welding used on the bars

The angle of the bend and the uniformity of the steel

The time taken to perform the test
