Fiber Reinforced Concrete

2019
Plain concrete is a brittle material with low tensile strain and strength capacities; the use of short, discontinuous fibers allows us to strengthen and toughen such material. Fibers are not generally added to concrete to increase its strength; the main role of the fibers is to bridge across the matrix cracks that develop as concrete is loaded, and ...

Fiber-reinforced concrete and ultrahigh-performance fiber-reinforced concrete materials

2020
In recent decades the growing interest in high-performance materials in civil engineering applications has met new requirements in terms of safety, costs, and sustainability. Fiber-reinforced concrete (FRC) is one of these subjects that has become a very promising material in civil engineering applications.

Basalt Fiber Reinforced Concrete

Advanced Materials Research, 2011
In this paper, mechanical performances of 480 specimens are tested and influences of basalt fiber ratio, slenderness, soakage material are studied. Results indicate that mechanical properties of BFRC are better than plain concrete. It can be found that the best mechanical performance may be get when the basalt fiber soaked by water-solubility material ...

Fiber Reinforced Concrete Extrusion

Journal of the Structural Division, 1975
Results of tests involving extrusion of fibrous concrete (FRC) indicate the feasibility of the process. Extrusion through a stationary die proves beneficial to the mechanisms governing material behavior. The results of flexure tests are considered for extruded steel and glass fibrous concrete.

Triaxial Tests of Fiber-Reinforced Concrete

Journal of Materials in Civil Engineering, 2001
This paper presents results of an extensive experimental parametric study of the mechanical response of various types of fiber-reinforced concrete tested under triaxial stress combinations. The objective of this study was to characterize the constitutive properties of these materials, with respect to fiber type and content, load path, condition at ...

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 ...

MICROMECHANICAL ANALYSIS OF FIBER-REINFORCED CONCRETE

1998
The present paper deals with the problem of modelling the complete macroscopic response of short fibre reinforced cementitious composites under unidirectional tensile loading. It is considered a concrete matrix with a periodic distribution of cracks and fibres.

HYBRID FIBER REINFORCED CONCRETE

2007
This paper describes the mechanical performance of hybrid fiber concrete with a maximum fiber dosage of 0.75 Vol.%. Two types of fibers were used: short straight steel fibers and long hooked-end steel fibers. The concrete compressive strength (fc,cub150) varied between 55 and 65 MPa, dependent on the fiber mixture.

Principles of Fiber-Reinforced Concrete

2021
It is possible to enhance the ability of crack control and inherent brittleness of ordinary concretes by integrating discrete fibers into concretes. Fiber-reinforced concretes are acknowledged as high-performance building materials due to their high levels of toughness under tensile and compressive loads.
