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.earthtoyes.shop/product-category/collections/
