  Concrete is the commonly used building material. It has to be poured into the formwork to take the appropriate shape of a structural element. Therefore, the used formwork affects the surface parameters and final properties of cementitious materials. This paper aims to study the effect of formwork surface texture parameters and release agents on the surface of cementitious materials. Including a reference formwork (F17-Ref), mineral oil (F17-MO), vegetable oil (F17-VO), polyethylene terephthalate coated (PET), and polymeric coated (C20C27) formworks were prepared. For this purpose, pre-crack demolding tests on cement paste samples and pull-off demolding tests on concrete samples were conducted to analyze the adhesion between cement paste/concrete and formwork. The results highlight that the specimens with polymeric-coated plates had the lowest surface roughness values, b.. Read More»
