WebRCK. Il “classico” calcestruzzo da sempre impiegato nelle costruzioni ordinarie, cioè l’Rck 300, oggi si denomina con la sigla C25/30 che si legge così: - la lettera C sta per “classe”; - il numero appena di seguito a C (cioè 25) indica la resistenza cilindrica del cls; - il numero a destra (cioè 30) indica la resistenza cubica. E ... WebApr 22, 2024 · La misurazione della resistenza a compressione del calcestruzzo avviene per mezzo di presse di carico su specifici provini, cilindrici o cubici, a 28-30 giorni dal prelievo, mantenuti in un ambiente protetto, in accordo con la norma UNI-EN 12390-2. L’ RCK è quindi il rapporto tra il carico applicato e l’area della sezione resistente dei ...
