Ductile Response of Basalt Fibre Reinforced Concrete Beams

Abstract

This paper presents the effects of adding basalt fibres on reinforced concrete beams. The fibre volume fraction Vf ranges from 0.0 to 2.0 %. First crack load, service load, yield & ultimate load and their corresponding deflections were noted. The ductility response of BFRC beams were evaluated. The results show that 1.5% by volume of basalt fibre improves the overall performances. The maximum increase in deflection and energy ductility was found to be 34 % and 39% respectively when compared to that of reference beam. The increasing application of basalt is noticed as an insulating material in the construction and automotive industry and less hazardous than asbestos fiber. Basalt fabrics are produce d for the structural, electro-technical purposes. Structural applications include electromagnetic shielding structures, various components of automobiles, aircraft, ships and household appliances.
