Recycled aggregates can match structural concrete strength

A new study challenges one of the most deeply rooted assumptions in civil engineering: that using recycled materials in structural concrete inevitably means sacrificing strength. Researchers from Escuela Superior Politécnica del Litoral, in collaboration with the University of Surrey, have demonstrated that recycled aggregates can be incorporated into concrete without compromising performance—provided certain technical limits are respected. The findings are published in the journal Construction and Building Materials.
