Abstract

MEMBERS USING BASALT REBARS AND HYSD BARS AS CONCRETE REINFORCEMENT By ABSTRACT Basalt rocks are essentially an igneous class of naturally occurring mafic extrusive rock. When basalt rock is heated to a molten stage and formed into fibres, it is mixed with epoxy resins and moulded to form basalt rebars. Today, basalt rebars are a part of emerging technology, where their tensile strength is observed around 800-1350 MPa. This study primarily focuses on integrating these basalt rebars into the concrete as a reinforcing material in flexural members and analyzing their behavior in theoretical and functional study relative to conventional HYSD reinforcement. In this study, 2 sets of concrete beam specimens of M25 design mix concrete have been prepared each of size 700 x 150 x 150 mm. One set is made of HYSD reinforcement and the other with basalt rebars, and are subjected to flexure testing, after immersion curing process for 28 days. The various characteristics including maximum load carrying capacities, deflection, flexural strength and first crack point have been observed. Finally, the viability and adaptability for basalt as reinforcement is understood after the test results, in comparison with theoretical analysis.
