What is the primary use of a bond breaker in concrete applications?

The primary use of a bond breaker in concrete applications is to facilitate ease of removal from forms. Bond breakers are materials applied to the surface of forms to create a barrier that prevents the concrete from directly adhering to the formwork. This allows for easier demolding once the concrete has cured, as the bond between the concrete and the forms is minimized.

In addition, using a bond breaker can help to prevent damage to the concrete surface during removal and ensure that the formed shapes remain intact. Other potential uses of bond breakers may include enhancing the surface finish of the concrete, but the main goal is to ensure a smooth and efficient demolding process, which is why ease of removal from forms is the correct choice.
