“…Based on the compressive and fracture responses, the analytical expressions for predicting the compressive and tensile stress-strain were proposed and used in this paper for the development of flexural modelling. For the experimental validation of the flexural model, it is mentioned in the earlier part that the experimental work and results used in this paper have already been published in [14]. However, for the reader's interest, the summary of the flexural test performed on 21 FRC beams containing PVA and basalt fibres (1-3% by volume) is given first.…”

“…e modelling procedure described in this paper is applicable to FRC structural elements subjected to flexural loading. It is to be noted that this paper is an allied of the previous work published [14] in which flexural test results of 21 FRC beams containing PVA and basalt fibres (1-3% by volume) were presented. is paper specifically focuses on the flexural modelling of the similar beams based on the suggested compressive [10] and tensile [11] stress-strain behaviours and their validation through experimental and finite element analysis approach.…”

A flexural capacity model for fibre-reinforced concrete (FRC) beams reinforced with PVA and basalt fibres is suggested for the rectangular beam sections. e proposed models are based on the concept of equivalent stress block parameters for both compressive and tensile stresses, similar to Eurocode and ACI code. e parameters are defined by allowing the conversion of the stress-strain models into equivalent rectangular stress blocks, similar to Eurocode 2. e flexural model is suggested to determine the loading capacity of 21 FRC beams containing up to 3% volume fraction of PVA and basalt fibres without reinforcing bars. In order to investigate the accuracy of the proposed flexure models, finite element analysis (FEA) of the same beams was carried out using the compressive and tensile stress-strain curves. Furthermore, 21 FRC beams subjected to three-point bending were tested.e results of the flexural models showed good agreement with the load-carrying capacity of the tested FRC beams, and the results of FEA of all beams showed a good correlation with the experimental results in terms of the maximum load, load versus midspan deflection patterns, and the maximum tensile strains.

“…Nihat Kabay [16] studied the influence of using different length (12mm and 24mm) and different content (2 and 4 kg/m 3 )of basalt fiber on compressive strength of concrete. they observed that flexural strength of BFRC increase up to 9% compared to normal concrete at 4kg/m 3 dosage of 12mm basalt fiber Nasir Shafiq, Tehmina Ayub and Sadaqat Ullah Khan [13] examined the mechanical properties of concrete containing 25mm basalt fiber and different content (1%,2%, and 3%) by total volume. they conclude that the flexural strength of BFRC increase up to 23.02% compared to normal concrete at 3%dosage of basalt fiber.…”

“…Abhijeet B. Revade and their fellows [33] derived that adding 12mm and 1, 1.5, 2% basalt fiber in concrete will increase in flexural strength of 11, 26, 35% respectively. Nasir Shafiq and their fellows [13] examined on silica fume concrete and metakaolin concrete by adding basalt fiber will give an increase in flexural strength. Anil Ronald and their fellows [34] conclude that using basalt fiber in geopolymer will increase flexural strength by 67.88%.…”

This paper represents the outcomes of some latest trends of research in the field of concrete composites prepared with chopped basalt fibers (CBF) as fillers. The paper summarizes noticeable findings of the experimental studies carried out to demonstrate the advantages and limitations of the addition of CBF in a conventional concrete specifically. The review inspired to conclude that the effect of addition of chopped basalt fibers has been studied by performing tests for the workability of fresh mixes, compressive strength, splitting tensile strength and flexure strength with varying fractions and sizes of CBF. It was noticed that the workability reduced with addition of CBF and the strength properties showed an increment due to the CBF addition. However, lacking the explicit knowledge on the optimum dosage and preferred aspect ratio of CBF from the durability perspectives requires attention. Moreover, a compound usage of CBF with prevailing additives namely polymers, fly ash, silica fumes may be one of the potential areas for the researchers. Therefore, a need of extensive experimental study can be proposed dedicated to a full length experimental program for durability studies on concrete containing CBF can be proposed. The research outcomes indicated that addition of CBF into the concrete may prove advantageous to overcome the durability issues of concrete.

The natural fibers are evolving in the construction industry in many forms due to its dominant characteristics since decades. This paper delivers a review of the behavior of basalt fiber reinforced concrete under static and dynamic loading conditions. The main aim of the paper is to signify the influence of basalt fibers in concrete as chopped fibers, minibars, rebars, and meshes by showcasing the physical and mechanical properties of the concrete. The proposed review paper furnishes a summary of obtainable evidence about the incorporation of basalt fibers in concrete under various loading conditions. The effect of size and volume fraction of the fibers in concrete subjected to static loading and dynamic loading is discussed and reviewed. Additionally, the optimum length, diameter, and aspect ratio of the fibers with its volume fraction depending on the constituents in concrete is exhibited. Basalt fibers, can operate as an exceptional reinforcing material which can replace the conventional reinforcement with appropriate implementation. Highlights Application of basalt fibers in concrete based on different loading conditions has been reviewed. Properties and applications of basalt fibers in various forms were assessed. Static and dynamic behavior of basalt fiber reinforced concrete has been summarized based on the studied literature. Addition of suitable forms and size of basalt fibers in concrete were examined. Parameters such as volume fraction, aspect ratio of basalt fibers has been highlighted.
