Experimental Investigation of Mechanical Properties of Basalt Fiber Reinforced Recycled Aggregate Concrete (BF-RAC)

Abstract

This study investigates the mechanical properties of Basalt Fiber (BF)-reinforced recycled aggregate concrete (RAC) in the context of the rapidly evolving construction industry, especially in developing countries. With a growing need for sustainable building materials globally, RCA is recognized as a viable alternative for natural aggregate. The research primarily focuses on analyzing the impact of BF with varying contents and an optimum length of 12mm on the mechanical properties of RAC at 28 days. The findings of this research emphasize the significance of BF content, identifying it as the main factor influencing concrete's mechanical properties within the tested fiber content range (0.15% to 0.25%). Notably, an optimal BF content of 0.2% is revealed, providing valuable insights for enhancing the sustainability and mechanical performance of concrete in the construction industry.
