TLDR
In this article, the physical and mechanical properties along with their freeze-thaw durability of concrete produced with concrete aggregates were investigated and test results presented, and it was observed that the unit weight, workability, and durability of the concretes produced through WCA decreased in inverse proportion to their endurance for the freezing and thaw cycle.About:

Performance of concrete made with commercially produced coarse recycled concrete aggregate
TL;DR: In this paper, performance tests have been carried out for fresh and hardened properties of concrete made with commercially produced coarse recycled concrete aggregate and natural fine sand, and the results indicate that the difference between the characteristics of fresh-and hardened recycled aggregate concrete and natural aggregate concrete is perhaps relatively narrow than reported for laboratory-crushed recycled aggregatecrete mixtures.

Properties of concrete made with crushed concrete as coarse aggregate
R. Sri Ravindrarajah,C. T. Tam +1 more
TL;DR: The effects of using recycled concrete aggregates instead of natural aggregates in concrete are: reduction in compressive strength up to 25%, reduction in modulus of elasticity up to 30%, improvement in damping capacity up to 20%, and higher amounts of drying shrinkage and creep as mentioned in this paper.
