CHARACTERISTIC MEAN STRENGTH AND TARGET MEAN STRENGTH

Where, fcm = mean strength, fck = compressive strength, 𝛔 = standard deviation. Therefore for designing concrete mix of a specified characteristic compressive strength, the design strength or the target strength is calculated by the above formula. For example, the designing of M20 concrete mix, the design strength is fcm = 20 1.65𝛔.
