Modern construction is placing an increasing emphasis on the use of materials with superior strength, stiffness, toughness, and durability. Concrete is one of the most utilized construction materials because of its tremendous strength, mounding ability, and durability. Concrete’s tensile strength and ductility both are significant disadvantages (toughness). Compaction is required for traditional concrete used in building construction and technical applications to provide strength, durability, and homogeneity. The traditional method of vibratory compaction causes delays and extra costs in projects, as well as posing major health risks owing to noise pollution on and around building sites. Flowable concrete, or SCC, can easily fill formwork and squeeze into small spaces without requiring much segregation or compaction. Recycling is the process of metabolizing waste materials to produce a new, usable good. Waste from building and demolition projects is also used to make recycled aggregate. This kind of recycled aggregate works well in concrete as a dependable replacement for natural aggregate. The use of aggregate from demolished buildings and abraded aggregates from the roadside in structural concrete is a significant step forward. The current research looks at how self-compacting concrete’s mechanical strength changes when natural aggregate is partially replaced with recycled material. To obtain sustainable concrete, roadside abraded aggregates are employed as a coarse aggregate partial substitution in concrete.
