Experimental and analytical investigation on flexural behaviour of ambient cured geopolymer concrete beams reinforced with steel fibers

, 2019
This study investigates the flexural behaviour of geopolymer concrete (GPC) beams reinforced with steel fibers. The effects of the volume fraction and fiber length on the flexural behaviour of GPC beams are investigated.

Experimental analysis of fiber‐reinforced recycled aggregate self‐compacting concrete using waste recycled concrete aggregates, polypropylene, and steel fibers

Structural Concrete, 2019
Self‐compacting concrete (SCC) is a cementitious composite which serves complex formworks without mechanical vibrations with superior deformability and high resistance to segregation.

Contribution of hybrid fibers on the improvement of sand concrete properties: Barley straws treated with hot water and steel fibers

, 2020
This study is a continuation of previous work undertaken on a sand concrete lightened by barley straws treated with hot water. Indeed, this type of lightweight concrete presented good thermo-physical properties.

Performance of Hybrid Fiber Reinforced Concrete with Steel Fibers and Polypropylene Fibers

Civil Engineering and Urban Planning 2012, 2012
The geometrical size and modulus of fibers are the main factors influencing the mechanical performances of fiber reinforced concrete. The use of different type of fiber in a suitable combination may potentially improve the overall mechanical performances of concrete and result in performance synergy.

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 ...
