Which statement about curing tilt-up panels is NOT true?

• A. Using a liquid membrane compatible with the bond breaker is an acceptable curing method.
• B. The curing method should consider time, temperature, and moisture.
• C. Maintaining satisfactory moisture content and temperature is important.
• D. Curing methods do not require compatibility with the bond breaker.

Answer: (D)

Curing tilt-up panels must be compatible with the bond breaker used on the form because the cure method interacts with the release surface and can affect both release and curing effectiveness. If the curing method doesn’t play well with the bond breaker, you can jeopardize form release or introduce surface or bonding issues during curing. A liquid membrane that is compatible with the bond breaker is an acceptable curing method because it protects moisture during cure without compromising the release surface. Curing should consider time, temperature, and moisture since these factors control the rate of hydration and moisture retention, which in turn influence strength and crack resistance. Maintaining proper moisture content and temperature is important to achieve the desired cure. Therefore, saying curing methods do not require compatibility with the bond breaker is not correct.
