A non-reactive oil or emulsion applied thinly to the inside of the molds to prevent the concrete from sticking. Step-by-Step Procedure for Making Specimens

Place the specimens in a room with a relative humidity of ≥ 95% and a temperature controlled at 20 °C ± 2 °C .

Crucially, the standard distinguishes between two types of curing environments that can be used depending on the objective of the test:

Procedures for making and curing specimens (cubes, cylinders, and prisms) for strength tests. Key Steps:

Apply vibration using a table or poker until the surface becomes relatively smooth and no large air bubbles emerge. Avoid over-vibration, which causes segregation.
