Utilizing alternative materials has become more popular in the construction sector in recent years to reduce the impact on the environment and mitigate pollution effects. One such material is glass powder, which can be used as a partial replacement for fine aggregate in concrete. Another trend is the use of basalt fiber, in particular, has gained popularity due to its eco-friendly manufacturing process and excellent mechanical properties. Although relatively new in the construction industry, basalt fibers are cheaper than other fibers and have been studied by researchers for their effect on compressive strength, flexural strength, and splitting tensile strength of fiber concrete. Similarly, poly vinyl alcohol fiber is a suitable polymeric fiber for use in concrete and has unique microstructure characteristics that present challenges in material design. In this project, the effect of adding basalt fiber and poly vinyl alcohol fiber on the compressive strength, flexural strength, and splitting tensile strength of fiber concrete was studied. Different volumes of fibers were added to the concrete and compared with conventional concrete. The results of the experiment showed that the addition of up to 0.3% volume of basalt fiber and poly vinyl alcohol fiber individually improved the compressive and flexural strength of the concrete. However, there was negligible influence of fiber addition on the splitting tensile strength. Basalt fiber and poly vinyl alcohol fiber could be utilized in concrete to improve its mechanical properties, and the test results showed that poly vinyl alcohol fiber had a higher splitting tensile strength and flexural strength that basalt fiber in the corresponding mix proportion. Overall, the study demonstrated the potential of alternative materials such as basalt fiber and poly vinyl alcohol fiber to improve the sustainability and strength of construction materials
