Question
What sieve size is the dividing line between fine aggregates (sand) and coarse
aggregates (gravel) used in concrete?
O A) 25 mm
O B) 12.5 mm
OO 14 mm
D) 5 mm
Concrete is required for an exterior column exposed to severe freeze thaw cycles.
The water to cementitious materials ratio is 0.37. If 120.1 kg of water is to be added
to the mix, what is the batch weight of the cement?
O A) 427.1 kg
O B) 324.6 kg
OC) 335.0 kg
O D) 320.0 kg
In Lab 6, a pycnometer was filled with water and then sand to determine the
value of the fine aggregate:
O A) Relative Density
O B) Bulk Density
OO Absorption
O D) Moisture Content
If you wanted to design a concrete mix using the minimum allowed water/cement
ratio, determine the mass of cement required if 150 kg of water is used in the mix:
O A) 600 kg
O B) 400 kg
OO 500 kg
OD) 300 kg
O O
