It is shown that synthesized rare–earth elements – lanthanum and cerium were detected as a result of the effect ultra‑deep penetration process (SDP) on welding zone two steel plates. When moving in clumps microparticles, channels are formed where fibers formed, which new chemical from group rare earth metals due to additional energy.

This Investigation aims to study the effect of adding Steel fibers with different volume fractions Vf (o.5, 0.75, and 1% by concrete) aspect ratio 100 on mechanical properties concrete, alsofinding influence petroleum products (Kerosene Diesel) Fiber Reinforced Concrete (SFRC).The experimental work consists two groups: group one specimens (cubes prisms) plain concrete reinforced steel fiber exp...

This paper details the effect of fiber reinforcement on mechanical characteristics by-products based one-part alkali activated material (AAM). Two different binder matrices were considered in this study, such as, plain slag, and ternary blended to understand their efficiency reinforced system. These with 1% v/v three fibers (steel, glass basalt) improve flexural performance high strength mortar...

Reinforced Concrete (RC) deep beams perform better structurally when steel fibers are added, as this reduces the need for web reinforcements, boosts shear strength, and helps to bridge cracks. The current ACI 318-19 code does not include predicting strength models account added in Steel Fibers (SFRC) without stirrups; therefore, structural engineers less motivated use them. To fill gap, databas...
