Release Agent

Definition

A release agent is a material used to prevent bonding of concrete to a form surface.

Purpose

The purpose of a release agent is to ensure that concrete does not adhere to the formwork, allowing for easy removal of forms and resulting in a smooth surface finish on the concrete.

Examples of Use

• Form release agents are applied to wooden or metal formwork to prevent concrete from sticking.
• Precast concrete manufacturers use release agents to ensure smooth removal of molds from concrete products.
• Decorative concrete applications use release agents to create patterns and textures without damaging the concrete surface.

Related Terms

• Formwork: Temporary molds into which concrete is poured to form structures.
• Mold Release: A substance used to prevent materials from sticking to molds.
• Concrete Finish: The texture and appearance of the surface of the concrete.

Notes

Selecting the appropriate release agent is important to ensure it is compatible with the form material and concrete mix, achieving the desired surface finish and ease of form removal.
