A significant advantage of glass-fiber-reinforced concrete panels over architectural precast concrete panels is which one of the following?

AIncreased strength

BIncreased quality control

CDecreased weight

DDecreased fabrication time

Show Suggested Answer

Suggested Answer: C

Glass-fiber-reinforced concrete (GFRC) panels offer several advantages compared to architectural precast concrete panels:

GFRC panels are lighter due to their thin profile and use of fiber reinforcement, reducing structural load and facilitating installation.

Precast concrete panels are heavier and thicker.

Strength of GFRC is adequate but typically not higher than traditional precast.

Quality control and fabrication time are comparable or vary depending on the project and fabrication process.

Therefore, the significant advantage is decreased weight.

I feel like D) Decreased fabrication time could be a factor too, especially since glass-fiber panels can be easier to handle. But I keep coming back to the weight issue.

I’m a bit confused about this one. I thought glass-fiber-reinforced concrete had advantages in strength, but I can’t recall if that’s a significant enough difference.

I remember practicing a similar question about the benefits of different concrete types. I think B) Increased quality control could also be a valid option, but I’m leaning towards C.

I'm a bit confused on this one. Is it talking about the advantages in terms of construction, cost, or something else? I'll have to re-read the question and options more closely.
