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.

TL;DR: In this article, a comparative analysis of the experimental results of the properties of fresh and hardened concrete with different replacement ratios of natural with recycled coarse aggregate is presented in the context of load testing of reinforced concrete beams made of the investigated concrete types.

TL;DR: In this article, the optimal choice of aggregate type and transport scenario in concrete production, employing a multicriteria optimization method taking into account technical, economical and environmental limits and constraints, was determined.

TL;DR: In this paper, a comparative environmental assessment of several different green concrete mixes for structural use was presented, and the best overall environmental performance was shown by the alkali activated fly ash concrete mix with natural aggregates and the high-volume fly ash recycled aggregate concrete mix.

TL;DR: In this article, the authors presented results of experimental investigation of concrete made with recycled concrete aggregate, low cement content and high content of different mineral supplements. But the results showed that the optimal combination of various mineral admixtures can reduce the basic disadvantage of concrete with high contents of mineral supplements, which allows certain structural applications of this type of green concrete.
