The commercial fibers designed especially for reinforcement of concrete composites were surface modified by oxygen ICP to attain their water wettability enhancement. The wettability development of thus treated fibers was observed through contact angle sizes between fiber surfaces and distilled water using a direct horizontal optical static method. Contac angle measurements were realized within one month after the treatment, while fibers were stored on the air on standard laboratory condition in the meantime. Both, the treated Concrix ES and BeneSteel fibers exhibited significant wettability increase. The enhanced wettability of modified fibers stayed approximately constant even after 30 days over the treatment execution in the case of BeneSteel, while in the case of Concrix ES the wettability decreased almost to the reference samples, respectively.
