How can you fix overworked concrete?

• A. Tear out and repour
• B. Cover to slow curing rate
• C. Add more aggregate and vibrate
• D. Patching or overlaying

Answer: (D)

Overworking concrete during finishing creates a weak, dusty surface with laitance and poor bond to the underlying concrete. The practical fix is patching or overlaying: you repair damaged spots with a repair material or apply a new thin layer on top to restore a smooth, strong, and well-bonded surface. Tearing out and repouring is an excessive remedy for typical surface flaws, usually reserved for major structural issues. Covering to slow curing is about how the concrete cures, not repairing a surface that has already been overworked. Adding more aggregate and vibrating won’t correct the weakened surface and can actually worsen segregation and finish quality.
