Compressive Strength Of Concrete Cylinder

Nov 28, 2019nbsp018332Where concrete is classified according to compressive strength, Table 7 of BS EN 206 should be used. The characteristic compressive strength at 28 days of 150mm diameter by 300mm cylinders or that of 150mm cubes may be used as classification. To convert the compressive strength f c into f cu value, refer to Table 7 of BS EN 206 as tabulated ...
