“…In recent years, basalt fibers have emerged as an alternative to glass fibers [7]. Basalt fibers are environmentally safe, nontoxic, and possess high stability and insulating characteristics [8]. In addition to the above mentioned properties, basalt fibers have better tensile strength than the * corresponding author; e-mail: sert@sakarya.edu.tr E-glass fibers, greater failure strain in comparison with carbon fibers and provide good resistance against chemical corrosion, impact load and fire with less poisonous fumes [9,10].…”

Soil reinforcement with natural and man-made fibers is one of the techniques to improve a number of mechanical and physical properties of soils. Although basalt originated fibers are currently being used for concrete, it is not an easy task to find a source in literature concerning the use of basalt fibers for soil improvement. In this study, basalt fibers have been used for this new aim. This study is an investigation into evaluation of the increase in soil strength, which is reinforced, in different percentages, by basalt chopped fibers. A silty soil sample has been chosen for this study and has been mixed, with 6, 12, and 24 mm long basalt fiber at varying contents. The unconsolidated undrained triaxial tests show that the addition of 24 mm long fibers into soil gives the maximum improvement in strength and the optimum fiber content (by dry weight of soil) is 1.5%.

“…The reason for this is that choice of a particular fibre type is based on price, availability, compatibility with cement, durability and the reinforcing potential in the cement composite (Akers, 2006). Possible alternative for currently used AR glass fibre in near future might become carbon and basalt when new fibre production techniques will offer significantly lower prices, better durability and cementitious mix workability (High, Seliem, El-Safty, & Rizkalla, 2015;Xu, Liu, & Li, 2015).…”

Modern alkali resistant glass fibers (ARG) modified with 17% ZrO2 are getting more popular as reinforcement of cementitious matrixes. Typical matrix compositions with quartz, Portland cement, 13 mm length ARG glass fibres and PCE superplasticizer can offer good workability, product quality and highly increased mechanical characteristics. In production of self compacting fibre reinforced premix highly siliceous fine sands with nearly round shape particles are usually preferred. This article investigates influence of particle shape for workability of glass fibre reinforced concrete when alternative fillers-crushed granite and regular sand are used. 12 compositions were made whith different quantities of fillers, changing quartz from 0% to 50% with alternative aggregates. Slump tests according to EN 1170-1 were made and showed major impact of particle shape characteristics on mix workability. When quantity of altrernative aggrates was increased, slump of fresh mix decreased and fibre-matrix segregation occurred. New workability factor W is offered and values calculated, to have numeric representation of workability. Alternative aggregates had no clear influence for flexural strenght, when beams 40×40×160 were tested. Compressive strength dropped by 25% when regular sand was used. Typical quartz matrix resulted in lower water absorbtion.

“…Issa et al [8] examined the shear strength and behavior of concrete beams reinforced with basalt fiberreinforced polymer bars with and without stirrups and observed significant improvements in the shear strength of RC beams with insufficient shear reinforcement strengthened with BFRP. High et al [9] investigated the use of basalt fiber bars as flexural reinforcement for concrete members and the use of chopped basalt fibers as an additive to enhance the mechanical properties of concrete. Jiang et al [10] studied the effects of the volume fraction and length of BF on the mechanical properties of fiber reinforced concrete and observed significant improvements in the tensile strength and flexural strength in their experiments.…”

Abstract-This research studied the influence of chopped basalt fibers (BFs) on the shear strength of reinforced concrete (RC) beams without stirrups. The beams including one reference and three basalt fiber reinforced concrete (BFRC) beams were tested under concentrated load at mid-span to determine the shear strength. The test parameters are volume fraction of basalt fibers (V f ) and shear span-to-effective depth ratio (a/d) of beam. The deflection of the beam and the cracking pattern were monitored during the test at certain stages of the monotonic loading until failure. It is observed that the contribution of BFs to the strength at the ultimate state decreases as volume fractions of BFs increase from 0% to 1.5%.
