Which statement is NOT true about water-reducing admixtures?
1) It increases the strength of the concrete by lowering the water demand
2) It increases the concrete slump without adding water
3) It increases the air content of the concrete
4) It improves the hardened concrete's impermeability
5) None of the above
It increases the air content of the concrete
Which of the following statements is True about the Portland Cement:
1) The strength of portland cement is determined by measuring the strength of
mortar made with Ottawa standard sand.
2) The Initial and Final Set time of Portland Cement should be determined using
either Vicat or Gillmore Penetrometer.
3) Per ASTM C150, the soundness (ability to retain its volume) of portland cement
(PC) paste, could be measured using an Autoclave Expansion apparatus.
4) All of the above are true
5) None of the above is true
All the above are true
All the essential and desirable attributes of Portland Cement Concrete (PCC), such
as durability, impermeability, resistance to volume changes, etc., depend on:

1) Its water/cement ratio

,2) The max size of coarse aggregates

3) How well and how long the portland cement concrete (PCC) has been cured

4) All of the above are true

5) None of the above is true
All the above are true
Which of the following statement is NOT a cause of Efflorescence (whitish
patterns appearing on the surface of PC concrete):
1) The concrete must have soluble mineral salts within it.
2) There must be moisture to dissolve the soluble salts.
3) There must be some degrees of sulfate present adjacent to the concrete
element
4) All of the above are true
5) None of the above is true
There must be some degrees of sulfate present adjacent to the concrete element
The quality of portland cement concrete depends on, more than any other factor,
the:
1) Water/cement (w/c) ratio of the portland cement concrete (PCC)
2) Quality of the paste of the portland cement concrete (PCC)
3) Reinforcing rebar used in the reinforced portland cement concrete (PCC)
4) All of the above are true
5) None of the above is true
Quality of the paste of the portland cement concrete (PCC)
Portland cement concrete (PCC) hardens or gains strength by the:

, 1) Hydration of the portland cement (PC)

2) Drying of the portland cement concrete (PCC) — caused by the evaporation of
some of the mix water

3) Adding of salts to the portland cement concrete (PCC) to promote a hardening
of the PCC

4) All of the above are true

5) None of the above is true
Hydration of the portland cement (PC)
Air-Entraining agents or admixtures are used in portland cement concrete can
potentially be good for:
1) Improving the durability of the cured and hardened portland cement concrete
(PCC) when exposed to frequent and severe cycles of freezing and thawing
2) Improving the workability of freshly mixed concrete
3) Having a more water-tight hardened portland cement concrete (PCC)
4) All of the above are true
5) None of the above is true
All the above are true
The most commonly used concretes in civil engineering construction are portland
cement concrete (PCC) and asphalt concrete (AC), where:

1) For portland cement concrete (PCC), the binder is the paste, which consists of
portland cement (PC), water, and admixtures

2) For asphalt concrete (AC), the binder is asphalt (cement), sometimes with
viscosity improving agents

3) For both concretes, the fillers are gravel or coarse aggregates (CA) and sand or
