“…In addition, the addition of steel fibers reduced the brittle nature of the material more effectively than stirrups. Analyzing the slope of the force (V)-deflection (δ) curves shown in Figure 16, it can be concluded that the steel fibers affected the bending stiffness, but the impact was not significant; which has been confirmed, in [15], in the case of elements with a high degree of main reinforcement. Yoo [71] and Ashour [72] also came to similar conclusions.…”

“…Considering the mechano-physical properties of SFRWSC and the shear capacity test results presented in this paper, as well as the flexural capacity values for beams made of this fibre-reinforced composite, as described in [ 15 , 36 ], the assumption can be made that this material can successfully be used as a structural material. The developed SFRWSC, the properties of which comply with the requirements set for structural materials, could be used as an alternative solution for ordinary concrete in some applications, providing an opportunity to utilise the waste sands piled in Pomerania (Poland), in the Middle East, or in North Africa.…”

“…This novel fibre composite material, featuring high compression and tensile strength, was designed based on a fine post-production waste aggregate. The research work described in [ 12 , 14 , 15 ] stated that a fibre composite based on waste sand containing 1–1.5% steel fibres has the best physicochemical properties. If the steel fibre content exceeds 1.5%, some tested material features decrease or improve insignificantly.…”

“…The research work published in [ 12 , 15 , 36 ] concluded that SFRWSC without steel fibres behaves like ordinary concrete in bent elements provided with conventional reinforcement. The addition of steel fibres considerably improves the flexural capacity of such elements, thanks to which, the reduction of conventional reinforcement due to bending moment is possible.…”

Inthis paper, we report the results of our research on reinforced concrete beams made of fine aggregate fibre composite, with the addition of steel fibres at 1.2% of the composite volume. The fine aggregate fibre composite is a novel construction material, in which the aggregate used is a post-production waste. Twenty reinforced concrete beams with varying degree of shear reinforcement, in the form of stirrups with and without the addition of steel fibres, tested under loading. The shear capacity results of reinforced concrete beams made of the fine aggregate fibre composite being bent by a transversal force, as well as the cracking forces causing the appearance of the first diagonal crack, are discussed. The stages of functioning of such elements are described. Furthermore, the effect of the steel fibres on the reduction of diagonal cracking is analysed. Computation of the shear capacity of the tested elements is performed, based on the Model Code 2010 and RILEM TC-162 TDF standards, for two variants of the compression strut inclination angle θ that measured during testing, and the minimum(in accordance with the Model Code 2010 standard). We found that the SMCFT method part of Model Code 2010 showed the best compatibility with the experimental results. The tests and analyses performed demonstrate that the developed novel fibrecomposite—the properties of which are close to, or better than, those of the ordinary concrete—can be used successfully for the manufacturing of construction elements in the shear capacity aspect. The developed fine aggregate fibrecomposite could serve, in some applications, as an alternative to ordinary concrete.

“…The average deflection value obtained for two beams of each series was used here for further analysis purposes. The system was also used for measurement of beam vertical displacements [27]. The deflection was measured with displacement sensors fitted in an aluminum strip fixed independently of the beam to the test the stand load bearing frame (Figure 3).…”

The article describes the selected methods of calculating the deflection of steel fiber reinforced concrete beams. Additionally, the results of the study on the deflection of steel fiber reinforced concrete beams based on waste sand are presented. This paper compares deflections measured during the four point bending test of the steel fiber reinforced, waste sand fine aggregate concrete beam with values determined in accordance with Eurocode 2, the proposal of Tan, Paramasivam, and Tan, the modified method of Alsayed, Bywalski, and Kaminski, and Amin, Foster, and Kaufmann’s method. The analysis conducted shows that the best accordance with the study and calculation results was obtained by using the modified Alsayed method.
