Question 1.
What is the primary purpose of the compressive strength test?
Show hintHide hint
Think about why we assess concrete in construction.
Question 2.
Name one type of specimen used in the flexural strength test.
Show hintHide hint
Consider what shape would represent bending.
3Question 3.
What is the main objective of the compressive strength test?
- To assess quality
- To measure flexibility
- To evaluate tensile strength
Show hintHide hint
Think about what makes concrete strong.
4Question 4.
Flexural strength testing mainly applies to which types of concrete structures?
- True
- False
Show hintHide hint
Recall where bending occurs.
Question 5.
Given a standard cube specimen with a maximum load of 350 kN and a cross-sectional area of 22500 mm², calculate the compressive strength.
Show hintHide hint
Remember the formula f_c = P/A.
Question 6.
A bond strength test shows a maximum pull-out load of 10 kN for a steel bar with a diameter of 12 mm and an embedment length of 100 mm. Calculate the average bond stress.
Show hintHide hint
Use the bond strength formula.
