Yes, the characterisrtic strength of a concrete is the same as the compressive strength
the compressive strength can be converted in to flexural strength by following formula of IS code 456-2000fcr=0.7^/- fck fcr= flexural strength fck= characteristic compressive strength in N/mm2
Minimum Compressive strength of first class brick is 10.5 MPa
The compressive stress allowed is 25N/mm2. However, the strength of a concrete element depends on the arrangement of loads. For compression, the element might buckle before it reaches its compressive stress.
