Flexural Behavior of Recycled Aggregate Concrete Beam with Varying Dosage of Steel Fiber

Md. Rejoan Chowdhury & Dipto Mondal · Journal of Engineering Research and Reports · 2024

Natural resource scarcity and demolition waste suggest that recycled stone aggregates to be used instead of fresh aggregates as an alternatives. Recycled aggregate provides less strength to concrete than natural aggregate. Fiber such as steel fibers can be added to concrete at a...
