Cylinder cube strength
WebSix different cube and cylinder specimens were investigated. Fifty-one, 76, and 102 mm (2, 3, and 4 in.) cylinders were tested alongside 51, 70.7, and 100 mm (2, 2.78, and 4 in.) cube specimens. The compressive strength of the concrete tested ranged from 80 to 200 MPa (11.6 to 29 ksi). In North America, there is currently only one UHPFRC WebA comparison between cube and cylinder strength of the concrete is required to know to get them an idea about the characteristics strengths to be used in different standards. For example, Eurocode uses the characteristic cylinder strength to represent the strength of …
