Experimental investigation of the mechanical properties of basalt fiber‐reinforced concrete

Abstract

This paper presents an experimental investigation of how varying the volume fraction of chopped basalt fibers affects the mechanical properties of fiber‐reinforced concrete (FRC). The fiber content is varied in the range of 0–2%. The main parameters investigated are workability, compressive strength, splitting tensile strength, flexural strength, and flexural toughness. Test results showed that the compression strength of concrete decreased marginally with the addition of basalt fibers in comparison with plain concrete. However, the mode of failure of FRC under compression is changed from the brittle to ductile. The splitting tensile strength of concrete is improved by 15% when basalt fibers with 2% volume fraction are added to the concrete mix. A significant increase of up to 75% is noticed in the flexural tensile strength of basalt FRC, with better post‐peak residual strength compared with the plain concrete. Furthermore, the flexural toughness of basalt FRC is increased by nearly three times that of the plain concrete based on the round panel tests.

Usage of Chopped Basalt Fibers in Concrete Composites: A Review

“…Hasan Katkhuda and their fellows [30] examined that adding of 18mm basalt fiber in plain concrete will increase in flexural strength while same will give max increase of flexural strength in recycled and treated recycled concrete aggregate by adding 1.5% basalt fiber. Shruti Jalasutram and their fellows [31] revealed that adding 12.7mm and 2% basalt fiber in concrete will increase max 75% of flexural strength of concrete. Wang Jun and their fellows [32] conclude that adding 30mm and 0.25% basalt fiber in concrete will give a min increase of 0.53% flexural strength.…”

“…Hasan Katkhuda and their fellows [30] conclude that increase in compressive strength while adding basalt fiber of 18mm length in concrete, but while replacing aggregate with recycled & treated recycled concrete aggregate it gives an increase in compressive strength when adding 0.5 & 1%, while decreases when adding basalt fiber 0.1 & 1.5%. Shruti Jalasutram and their fellows [31] examined that 12.7mm length and 0.5,1,1.5,2% of basalt fiber added in concrete it gives decrease in compressive strength 0, 2.6, 2.08, 2.86% respectively. Wang Jun and their fellows [32] Revade and their fellows [33] added 0.5, 1.0, 1.5% basalt fiber of 12mm length results increase in compressive strength 13.27, 11.15, 7.06% respectively.…”

Shruti Jalasutram and their fellows [31] determine that adding 0.5 & 1% basalt fiber of 12.7mm length will give min and max tensile strength of 3.4 & 13.7% respectively. Wang Jun and their fellows [32] researched that adding 0.2% of 30mm length basalt fiber will decrease in tensile strength of 2.5%, but for same length 3% of basalt fiber will give an increase in tensile strength of 22.5%.…”

High‐velocity impact experiment of concrete panels reinforced with crimped wire mesh and steel fibers

“…Because crimped wire mesh is being used as much as reinforcing bars in walls and slabs, an experimental research using crimped wire mesh is highly important and necessary (Figure ). Particularly, there has been only a few research on wire mesh‐reinforced concrete (WMRC) with steel fibers, which has shown potential to improve the mechanical properties of concrete such as ductility, toughness, and bond strength . Therefore, this paper deviates from the evaluation of impact resistance of concrete which has largely taken a traditional view of material, but is an outcome of an experimental research project in evaluating the impact resistance of concrete conditioning on the presence or absence of crimped wire mesh, evaluating the impact resistance of steel fiber‐reinforced concrete (SFRC), and gauging the impact resistance of wire mesh‐ and steel fiber‐reinforced concrete panels.…”
