Form release agents are applied to the form contact surfaces to prevent bond and thus to facilitate stripping. Experiments have been performed to clarify the performances of form release agents that are made for the experience. Tests for following items are performed : (1) Maximum compressive loads applied at a steel core embedded in concrete. (2) Maximum tensile loads applied at the form vertically. (3) The compressive strength of mortar which contains release agent. (4) Chemical analysis of the cement paste which is in contact with form release agent. (5) Distribution of the bubbles at the concrete surface which was contact with a form. Based on the limited number of test, several oils and aditional agents are recommended.
