Toughness Characterization of Steel‐Fiber Reinforced Concrete

26-04-1993  For the fibers and the matrices investigated, a strong influence of both fiber geometry and matrix strength on the toughness characteristics of fiber‐reinforced concrete was observed. End‐deformed fibers were, in general, found to perform superior

01-04-2000  1. Introduction. The addition of steel fibers significantly improves many of the engineering properties of mortar and concrete, notably impact strength and toughness , .The enhanced performance of fiber-reinforced concrete compared to its unreinforced counterpart comes from its improved capacity to absorb energy during fracture.

Toughness Characterization of Steel‐Fiber Reinforced Concrete

The paper describes an experimental program in which four deformed commercial fibers with widely different geometries were investigated in steel‐fiber reinforced concrete. Three matrices with compressive strengths of 42, 52, and 85 MPa were reinforced with fibers at a dosage rate of 40 kg/m3. Compressive and flexural strengths were measured along with the elastic moduli.

01-03-2004  The major advantage of fiber-reinforced concrete (FRC) over its plain counterpart is in its improved energy absorption capability, or ‘toughness.’ There are currently several standard test methods available to characterize the toughness of fiber-reinforced concrete, but little is known of the relationship between the toughness results they produce for a given fiber-reinforced concrete.

Flexural Toughness ofSteel Fiber Reinforced Concrete

Steel fiber reinforced concrete (S.F.R.C.) is distinguished from plain concrete by its ability to absorb large amount ofenergy and to withstand large deformations prior to failure. The preceeding characteris­ tics are referred to as toughness. Flexural toughness can be measured by taking the useful area underthe load-deflectioncurve in flexure.
