Compression specific toughness of normal strength steel

Compression toughness tests were carried out on concrete cylinders reinforced with three different aspect ratios of hooked-end steel fibers 60, 75, and 83 and six different percentages of steel fibers 0.5, 1.0, 1.25, 1.5, 1.75, and 2.0% by volume of concrete. Cyclic Response of Non-ductile RC Frame with Steel Fibers End-hooked steel fibers (aspect ratio = 80) of 1.0% volume fraction were used in the SFRC mix for a distance of one-and-half times the member size near the joint regions. adopted in the strengthening of the existing RC buildings, fiber-reinforced concrete can be used in the new buildings in order to reduce the reinforcement detailing

Steel fibers used as fiber-reinforcement are locally produced. The manufacturer of the fibers is "Spaji", Kobinica, Serbia. Adopted fibers are bent on ends (hooked), dimensions 30x0.6 mm, with aspect ratio l/d =50, in quantity of 60 kg/m3 (0.45% of volume). Basic Earthquake-Resistant Coupling Beams without Diagonal fiber-reinforced concrete to member shear strength, where f c moment capacity being reached at both ends of the coupling beam would be close to the upper limit in with a 1.5% volume fraction of high-strength hooked- steel fibers was selected for use in the coupling beams.

Experimental Study on Torsional Behaviour of Hooked

The shape of steel fiber used was hooked-end steel fibers with an aspect ratio (l/d) 66. The hooked-end steel fiber used is presented in Fig 1. Steel fibers were added in concrete in a volume fraction of 0.5%, 1%, 1.5% and 2%. The properties of steel fiber is given in Table 2. Fig. 1:Hooked-end steel fiber FIBER REINFORCED CEMENT COMPOSITES Fiber reinforced cement (FRC) composite materials are basically mortar and concrete composites made with addition of different types of fibers which represent a special micro-reinforcement. Uniformly dispersed fibers are strengthening the cement matrix, thus improving the

Fibers Free Full-Text Meso-Scale Formulation of a

These laws are derived by considering both the fiber-to-matrix bond mechanism and fiber anchoring action possibly due to hooked ends. The paper includes a numerical implementation of the proposed theory, which is validated against experimental results dealing with fiber-reinforced cement composites reinforced with different short fibers. Flexural Behaviour of Ferro cement Slab Panels Using May 06, 2014 · P.B. Sakthivel et al-Thin Cementitious Slabs reinforced with Stainless Steel Fibers(Journal of mechanical and civil Engineering) IOSR-JMCE Volume 4, Issue 2 (Nov-Dec. 2012). M.N.Soutsos et al.-Flexural performance of fibre reinforced concrete made with steel and synthetic fibres Construction and Building Materials 36 (2012) 704710.

Hysteretic Behavior of Reinforced Concrete Coupling Beams

The purpose of this study was to evaluate the structural performance of steel fiber reinforced concrete (SFRC) coupling beams. Reversed cyclic loading tests were performed with full-scale specimens. The main variable for the tests was the volume fraction ratio of the steel fibers. The results showed that the maximum strength was increased by about 11% with 1% of steel fibers incorporated, and INTERNATIONAL JOURNAL OF SCIENTIFIC & The hooked end steel fiber with 60 mm length and polypropylene fibers with 19 mm length were used in this study. The test results show improvement in flexural capacity of reinforced concrete beams. In this experimental study, the flexural cracking behavior of steel fiber-reinforced concrete was investigated.

KR101596246B1 - Arched steel fiber for cement

The present invention relates to an arched steel fiber for a reinforcing cement material. The arched steel fiber for the reinforcing cement material improves a mechanical performance such as tensile strength, bending strength, and energy absorption performance of a cement complex by bending both ends; and having an arch shape of an arched steel fiber main body in a longitudinal direction to Mechanical Properties of Steel Fibers and Nanosilica Jan 01, 2018 · The tensile strength of steel fibers (hooked at both ends) was 1345 MPa. The length of the steel fiber was 35 mm, and the aspect ratio was 64. The nanosilica was white powder with an average particle size of 30 nm, and its apparent density was 30-60 g/l.

Mechanical properties of steel and polymer fiber

Dec 17, 2019 · Polymer fibers along with regular hooked steel fibers were chosen as the reinforcements. As fiber reinforced concrete is commonly employed in tunneling practices as the lining, strength and toughness classes of both polymer fiber reinforced concrete (PFRC) and steel fiber reinforced concrete (SFRC) were evaluated in accordance with EFNARC. Modification for Ductile Detailing of Beam Column JointsB. Steel fibers . When steel fibers are added to mortar, Portland cement concrete or refractory concrete, the flexural strength of the composite is increased from 25% to 100% - depending on the proportion of fibers added and the mix design. Steel fiber technology

Prediction of the Nominal Bending Moment Capacity for

increase in flexural strength by more than 8% for end hooked fibers compared to straight fibers. Yang et al. [12] examined the flexural behavior of UHPC beams (180×270×2900 mm) with steel rebar ratios less than 0.02 (0.006, 0.009, 0.012, 0.0131, 0.0196) and straight steel fibers with a volumetric ratio of 2% and aspect ratio of 65. The UHPC was Steel Fiber In Anping, Steel Fiber Dealers & Traders In Find the top steel fiber dealers, traders, distributors, wholesalers, manufacturers & suppliers in Anping, Hebei.

Steel fibre reinforcing characteristics on the size

Jan 01, 2014 · Glued steel fibers used were of 35 mm length and 0.5 mm diameter (l/d ratio 70) at 0.5%, 1.0%, and 1.5% by volume fraction ([V.sub.j]) of concrete, respectively. The effect of steel fibre addition in fly ash based concrete (F/c ratio 0.6) showed better strength enhancement, when compared to normal size of concrete specimen (MC1) of 100 mm depth.Steel fibers for replacing minimum reinforcement in beams Jan 22, 2021 · Two identical SFRC beams (TB3-SFRC25, TB4-SFRC25) were reinforced with 25 kg/m 3 of steel fibers and, lastly, other two identical SFRC beams (TB5-SFRC50, TB6-SFRC50) contained 50 kg/m 3 of steel fibers. The hooked-end steel fibers used in this study were 30 mm long, had a diameter of 0.35 mm and a tensile strength of 2200 MPa.
