Experimental Studies on Fiber Reinforced High Strength Concrete on Rigid Pavement

EasyChair Preprint 8034

Abstract

High-performance concrete is one that aids in all aspects of overcoming practical obstacles as well as other functionality of any structure. Concrete pavements, high-rise buildings, long-span bridges, hydraulic systems, and other applications all benefit from the use of high-performance concrete. With the addition of fibres to the concrete mix, the qualities of the concrete improve dramatically. Many research projects are currently underway to make high-performance concrete more cost-effective and durable by including supplemental cementation ingredients and alternative replacement aggregates. The purpose of this study is to investigate the mechanical properties of fibre reinforced high performance concrete by substituting foundry sand and crushed concrete waste for fine and coarse aggregate, respectively. Every 5% interval, the percentage replacement of foundry sand ranges from 0% to 40%, and every 10% interval, the percentage replacement of crushed concrete waste varies from 0% to 40%. Mechanical parameters of high performance concrete were tested, including crushing strength, flexural strength, split tensile strength, shear strength, and impact strength. For the preparation of high-performance concrete, M80 Mpa concrete is used. The IRC44:2017 rules and recommendations were followed during the mix design process. To improve the performance of the concrete, the proper dosage of super plasticizer was maintained. Polypropylene fibres weighing 0.3 percent of the cement weight were employed in this study. Mechanical qualities were determined by producing certain mould sizes for specific tests, which were cured for 7, 14, and 28 days, with the results tallied and explained for each day.
