Demolished concrete is collected from sites and put through crushing machines. These machines can reduce larger rocks to smaller rocks, gravel, or even dust! The concrete can be refined for rebar, wood, or other metal chunks before being added to these machines. ... Recycled concrete aggregate offers many diverse advantages, among the most ...
The study conducted axial tensile strength tests on concrete samples that replaced conventional aggregates with recycled aggregates. In Series I, using FNG instead of FNA resulted in a reduction in compressive strength by 12.8–49.8% and tensile strength by 14.5–44.6%. If the proportion of FNG exceeds 50%, compressive strength decreases by more …
