Steel fiber reinforced concrete

Materials Science and Engineering, 1976
Abstract The task of evaluating what is unknown about fiber reinforced cement or concrete is difficult. One should identify the important aspects which must be investigated, and to a large extent this becomes the opinion of the writer. However, it does appear that more thinking is needed in respect of the details of the basic mechanics of ductile ...

How do steel fibers improve the shear capacity of reinforced concrete beams without stirrups?

Composites Part B: Engineering, 2019
Even though the structural behavior steel fiber reinforced concrete (SFRC) has been extensively researched, structural applications are still limited. One barrier to its implementation is the lack of mechanical models that describe the behaviour of SFRC ...

Effect of different fibers (steel fibers, glass fibers, and carbon fibers) on mechanical properties of reactive powder concrete

Structural Concrete, 2020
In the present study, reactive powder concrete (RPC) was investigated with three different types of single fibers that is, steel fiber (SF), glass fiber (GF), and carbon fiber (CF).

Tension-stiffening effect in steel-reinforced UHPC composites: Constitutive model and effects of steel fibers, loading patterns, and rebar sizes

Composites Part B: Engineering, 2019
The tensile performance of steel-reinforced concrete members is closely associated with the bond interaction between concrete and the embedded rebar. Ultra-high performance concrete (UHPC) is a rapidly emerging concrete material that has an ultra-high ...
