Mechanical behavior of three generations of 100% repeated recycled coarse aggregate concrete

Abstract Demolished concrete generates significant volume of construction and demolition (CD however, all mixes successfully achieved their target strength at 56th day expect the 3rd generation concrete. Another interesting finding of this study shows that even the 3rd generation concrete could surpass the target strength by at least 25% while considering long term strength gain. The stress–strain curves of repeated recycled concrete are also presented and discussed.
