Moreover, it is evident …
The use of crushed brick as a concrete aggregate essentially decreases a large amount of C&D waste as well as the demand for natural aggregate (NA) in a sustainable approach [1], [2]. However, the lack of knowledge on the performance of concrete incorporating waste crushed brick is a barrier to reuse it in concrete [17] .
