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.

SUMMARYThis paper investigated the dynamic behavior of basalt fiber reinforced concrete (BFRC) after elevated temperatures by using a 100-mm-diameter split Hopkinson pressure bar apparatus. Changes in weight and ultrasonic pulse velocity (UPV) were also studied. The results indicate that the weight losses of BFRC before cooling increase with temperature, while a reduction in weight loss value is observed after water cooling. The UPV values of BFRC decrease constantly as temperature increases, and the measured velocities under the same temperature increase with fiber content as temperature exceeds 200°C. For a given temperature, the strain rate, dynamic strength, critical strain, and impact toughness of BFRC increase with impact velocity. For a given impact velocity, the increasing temperature generally leads to an increase in strain rate and critical strain and results in a decrease in dynamic strength and impact toughness except in the case of 200°C. At 200°C, however, a marginal reduction, even an improvement in dynamic strength is observed, and the impact toughness initially decreases, then increases with loading rate when compared with that at room temperature. Basalt fiber is effective in improving the strength performance, deformation capacity, and energy absorption property of concrete after high temperature.

Experimental and analytical study of hybrid fiber reinforced concrete prepared with basalt fiber under high temperature

The usage of mineral basalt fibers is a relatively novel and popular topic nowadays due to its abundant availability, low cost, and higher temperature resistance. In addition, the establishment of analytical models is beneficial because the experimental work is more time-consuming and expensive. Therefore, in this study, the inorganic mineral basalt fibers with different length and content in hybrid fiber concrete composite are investigated to assess its suitability at room temperature and under high temperature. In addition, a new analytical model for stress-stain curve of hybrid fiber concrete composite is developed and compared with the models in previous studies.The microstructure examination is also conducted after exposure to high temperature to explore the fiber morphology and interaction with matrix. The substantial improvement was indicated by addition of basalt fiber in hybrid fiber concrete for stress-strain response, peak stress, elastic modulus, peak strain, ultimate stain, toughness, and specific toughness at room temperature and at 850 C. It was revealed that the basalt fiber had demonstrated overall good appropriateness in the hybrid fiber concrete composite for all the compressive properties. Moreover, the proposed analytical model could be useful for prediction of analytical behavior from experimental data under high temperature for the research and design purposes.
