Abstract
This research paper looks at how Basalt Fiber Reinforced Concrete (BFRC) works and how strong it is when mixed with silica fume. Regular concrete made with Portland cement has low tensile strength. It also breaks in a way and does not bend much before breaking. To fix these problems small pieces of basalt fiber were added to the concrete. The amount of fiber varied from 0.0% to 2.5%. The fiber was added in steps of 0.5%. At the time 10% of the cement was replaced with silica fume. The study looked at two types of mixes called M50 and M60. These were tested after 7 days and 28 days of curing. The study checked things like how easy the wet concrete was to work with how heavy it was when wet or dry how strong it was when pushed how strong it was when bent how strong it was when pulled apart and how well it stuck to materials. The results show that adding up to 1.5% of basalt fiber makes the concrete much stronger and better at handling cracks.
