Properties of sustainable concrete containing fly ash, slag and recycled concrete aggregate
TLDR
In this article, the suitability of using more sustainable concrete for wind turbine foundations and other applications involving large quantities of concrete was investigated, which was accomplished by partial replacement of cement with large volumes of fly ash or blast furnace slag and by using recycled concrete aggregate.About:

Comparisons of natural and recycled aggregate concretes prepared with the addition of different mineral admixtures
TL;DR: In this paper, the performance of natural and recycled aggregate concrete prepared with the incorporation of different mineral admixtures including silica fumes (SF), metakaolin (MK), fly ash (FA) and Ground granulated blast slag (GGBS) was determined.

Enhancing the durability properties of concrete prepared with coarse recycled aggregate
Shi-Cong Kou,Chi Sun Poon +1 more
TL;DR: In this article, the effects of incorporating Class F fly ash in the concrete mix design to mitigate the lower quality of recycled aggregates in concrete is presented, and the results show that one of the practical ways to utilize a high percentage of recycled aggregate in concrete, is by incorporating 25-35% of fly ash since some of the drawbacks induced by the use of recycled aggregation in concrete could be minimized.

Use of recycled concrete aggregate in fly-ash concrete
TL;DR: In this article, the effect of both partial and full replacement of natural coarse aggregates by coarse RCA in a fly ash concrete is discussed. And the results obtained showed that while embedding high amount of the RCA could lower the resistance to chloride penetration and carbonation of concrete still comparable design strength to that of the control mix might be achieved.

Mechanical and elastic behaviour of concretes made of recycled-concrete coarse aggregates
TL;DR: In this paper, an investigation of mechanical behavior and elastic properties of recycled-aggregate concretes is presented, which shows that structural concrete up to C32/40 strength class can be manufactured by replacing 30% virgin aggregate with recycled-concrete aggregate.

Mechanical Properties of Recycled Aggregate Concrete Under Uniaxial Loading
TL;DR: In this article, the compressive strength and the stress-strain curve (SSC) of recycled aggregate concrete (RAC) with different replacement percentages of recycled coarse aggregate (RCA) are investigated experimentally.

Effect of microstructure of ITZ on compressive strength of concrete prepared with recycled aggregates
TL;DR: In this article, the influence of these aggregates (recycled and natural) on the microstructure and compressive strength of the new concrete were studied, and the results are explained by the differences in porosity and pore structure of the two types of aggregates, and possible interactions between the aggregates and the cement paste.

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.

TL;DR: The use of Synchroton sources in the study of Cement Materials as discussed by the authors has been shown to be useful in the analysis of Cements and their applications in many applications.
