This study investigated the hybrid effects of micro-steel (MS) and basalt fibers (BF) on the physico- mechanical properties and durability of mortars with and without silica fume (SF). Three groups of mixtures containing SF contents of 0%. 10 % and 20 % as cement replacement were produced with the inclusion of 0. 25 %. https://www.roneverhart.com/OTTO-CAP-5-Panel-Mid-Profile-Mesh-Back-Trucker-Hat-OTTO-32-285/
