Durability of recycled aggregates concrete: a safe way to sustainable development
TLDR
In this paper, the mix design nomogram (MDN) is used to compare properties and behaviors of different concretes, and the results show that the family concrete with the highest pore volume and with the same compressive strength of 20, 30, and 40 MPa (2900, 4350, and 5800 psi) did not always correspond to the concrete family with high degree of carbonation.About:

Comparative environmental assessment of natural and recycled aggregate concrete.
TL;DR: It is concluded that utilization of RAC for low-to-middle strength structural concrete and non-aggressive exposure conditions is technically feasible and the environmental impacts are slightly larger for RAC than for NAC but the total environmental impacts depend on the natural and recycled aggregates transport distances and on transport types.

Durability performance of concrete made with fine recycled concrete aggregates
Luís Evangelista,J. de Brito +1 more
TL;DR: In this paper, different concrete mixes with increasing rates of substitution of fine natural aggregates with fine recycled aggregates from crushed concrete were prepared and tested, and the results were then compared with those for a reference concrete with exactly the same composition and grading curve, but with no recycled aggregate, drawing some conclusions on the feasibility of using this type of aggregate in structural concrete.

Utilisation de l'absorption d'eau des bétons comme critères de leur durabilité—Application aux bétons de granulats recyclés
TL;DR: Les granulats issus du recyclage des produits de demolition s'inscrivent dans le cadre des materiaux locaux de substitution, mais leur valorisation dans les betons hydrauliques est actuellement freinee par le fait qu'ils sont consideres comme "granulats hors normes".
