Q. In concrete mix design, what does the term 'workability' refer to?
A.
The strength of the concrete
B.
The ease of mixing and placing concrete
C.
The durability of the concrete
D.
The cost of the concrete mix
Solution
Workability refers to the ease of mixing, transporting, placing, and finishing concrete without segregation.
Correct Answer:
B
— The ease of mixing and placing concrete
Q. Which of the following factors does NOT affect the water-cement ratio in concrete mix design?
A.
Type of cement used
B.
Environmental conditions
C.
Size of aggregates
D.
Color of the concrete
Solution
The color of the concrete does not affect the water-cement ratio; it is influenced by the type of cement, environmental conditions, and aggregate size.
