-
A.
Better
-
B.
Slow
-
C.
Low
-
D.
Fair
Correct Answer:
A. Better
Explanation:
Vibrating concrete before grouting is a standard construction practice used to consolidate the mixture. This process uses mechanical oscillations to remove entrapped air bubbles and voids that naturally form during pouring. By eliminating these pockets, the concrete becomes denser, more uniform, and less porous. This results in significantly higher structural strength, improved durability against environmental factors, and a smoother surface finish, all of which represent a higher quality of concrete compared to non-vibrated samples.
