MoreNov 28, 2019· Table 2.1: Table 7 of BS EN 206. Note that the f cu and f c’ are both concrete characteristics pertaining to the compressive strength of concrete. The difference is that the first uses a cube sample while the latter uses a cylindrical samples/specimen of concrete during testing.

MoreCompressive strength of concrete cube test provides an idea about all the characteristics of concrete. By this single test one judge that whether Concreting has been done properly or not. Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures.

MoreThe concrete minimum compressive strength will be specified by the client/designer in a specific format. An example of this is given below: C40/50 The 40 is the compressive requirement of 40 N/ mm² of a crushed 100m concrete core and the 50 is a compressive requirement of 50 N/mm² for a crushed concrete cube. Therefore using the
