“…The S a parameter, associated to the ability to trap cement particles, was 0.9 µm for the bare formwork skin, in agreement with data reported by Libessart et al [11][12], and 2.5 µm for the coating. According to the cement particle size distribution measured by ASTMsponsored round-robin tests [34], around 5% and 15% of the finest cement particles would penetrate into the surface of the bare and coated formwork respectively, suggesting an enhanced cement-to-formwork mechanical adherence [35] and friction [36] with the use of the coating.…”

“…Les différents travaux conduits sur l'influence de la rugosité dans le contexte du coffrage rapportent essentiellement une caractérisation de la rugosité suivant le paramètre de rugosité de profil Ra, parfois Rt. Certains auteurs [11,28] élargissent la caractérisation à d'autres paramètres. Les paramètres de profil comme par exemple Ra sont souvent utilisés pour caractériser les morphologies de surface [30].…”

“…Afin de définir des parois qui offrent des facilités de séparation avec le béton, il faut analyser les paramètres influençant l'adhésion coffrage/béton. De nombreux auteurs ont étudié l'interface béton/agent de démoulage/coffrage [2][3][4][5][6][7] et la formation de la peau du béton en contact avec l'agent de démoulage et/ou la paroi [5,[8][9][10][11]. Cette peau, dont l'épaisseur varie du micromètre au centimètre selon la nature du béton, du coffrage et de la cure [12], est constituée principalement de ciment en surface.…”

“…According to p.5.3.6 of common standard 70.13330.2012, concreting procedure should be developed with provision of concrete joint location, subject to erection technology for the building and the structure, as well as to its construction peculiarities; whereas, necessary ruggedness of concrete-surface contact within the concrete joint, as well as ruggedness of the structure subject to concrete joint availability, must be ensured. However, according to article authors, observance of only joint arrangement technology is insufficient to provide for ruggedness of the whole structure; therefore, it is necessary to consider issues of formwork dismantling [9][10][11] in construction joint locations.…”
