Experimental and numerical studies are carried out in this study to characterize the flexural properties of ultra-high-performance fiber-reinforced concrete (UHPFRC) beams with and without an initial notch reinforced with micro steel fibers in overall ratios of 2% by volume. Dimensions of the notch were 5 mm in width. and 25 mm in height. For this purpose. https://parisnaturalfoodes.shop/product-category/bcaa-xdm-spiked-powder-berries/
