Abstract: In the present study, durability performance of fly ash concrete was tested by using k-value (cement efficiency) concept given in EN 206 Standard. Two different approaches were compared: 1) prescribed k-value in the standard (k = 0.4) and 2) measured (or determined) k-value by compressive testing as explained in CEN/TR 16639 Technical Report. Durability performance was based on depth of penetration of water under pressure (EN 12390-8). Concretes with and without fly ash (Class F) with three different water/binder ratios (w/c = 0.40, 0.50 and 0.60) were tested and the results were compared.
