The inclusion of fibers in concrete results in improved energy absorbing characteristics of the concrete. Dubai, UAE This study assesses the main mechanical and fracture properties of PFRC by using conventional and self-compacting concrete with various dosages. Behfarnia, K, Behravan, A. Every published material will be provided with DOI and will remain the permanent link of that article. Mixing shall be as recommended by the manufacturer such that the fibers do not ball up. Polyolefin fibers shall meet the Moreover, increasing the amount of fiber presented a growth in rupture modulus as well as splitting tensile strength. Click here to become an online Symposium Papers subscriber. polyolefin fibers in portland cement concrete pavement The North Dakota Department of Transportation (NDDOT) has constructed an experimental white topping project. ACI members have it…they are engaged, informed, and stay up to date by taking advantage of benefits that ACI membership provides them. Unless otherwise specified, a minimum of 3.5 pounds per cubic yard of polyolefin fiber reinforcement shall be evenly distributed into the mix. In this study, a real application of polyolefin fiber–reinforced concrete is reported. Concrete is weak in tension and fibers are added to it to make it ductile. The increase of the bending tensile strength and the uniaxial tensile strength of concrete with polyolefin macrofibers reinforcement in This new polyolefin fiber-reinforced concrete with enhanced fatigue, impact resistance, modulus of construction of durable highway structures. Phone: 1.248.848.3800, Home > Publications > International Concrete Abstracts Portal. The results showed that the highest compressive strength was obtained in LWC containing 1% fiber led to an increase of about 8%. Polyolefin fibers by having low Young's modulus (9 ≤ E ≤ 20 GPa) have been designed to control the post-cracking behavior of concrete . Concr. Polyvinyl alcohol fiber weakens axial compressive strength, splitting tensile strength and shear strength of concrete. Fax: 1.248.848.3701, ACI Middle East Regional Office Thomson Reuters Master Journal List (Web of Science). It is a great honor for the Civil Engineering Journal to be indexed in Web of Science (ISI). Flexural Toughness of fiber Reinforced Concrete, (Standard SF4),” JCI Standards for Test Methods of Fiber Reinforced Concrete, Japan Concrete Institute, 1983, pp. However, failure of fiber reinforced concrete is initiated by pulling out of fibers, failing to utilize their full capacity. Invalid Email Address. Brandt A. Arash Sedaghatdoost Such results were obtained with fibers embedded in high-performance concrete matrixes. One of the commonly used methods, for this purpose, is the addition of steel fibers of different geometries. Free Online Library: Performance evaluation of hybrid fibre reinforced concrete with polyolefin and basalt fibres. Compressive, flexural, and splitting tensile strengths of the sample were measured. 45-51. • Significance of Test These tests were designed to show the ductile, elastic/ plastic behavior and post crack load carrying capacity of fiber reinforced concrete. Results show that discrete fibers had little effect on elastic modulus for fiber-reinforced concrete (FRC) with coarse-to-fine aggregate ratio (C/S) greater than 1. Polyolefin FRC was used for construction of a thin bridge deck overlay, a Jersey barrier, a full depth bridge deck slab, whitetopping (concrete on scarified asphalt pavement), and full depth pavement.
