Shear performance of reinforced concrete beams incorporating recycled concrete aggregate and high-volume fly ash
TLDR
In this article, the authors investigated the shear capacity of full-scale reinforced concrete beams fabricated with high volume fly ash and coarse recycled concrete aggregate (RCA), and found that the average shear performance of the SC beams was 18% and 16% lower than those of the FA50 and RCA50 beams, respectively.About:

Effect of incorporation of high volume of recycled concrete aggregates and fly ash on the strength and global warming potential of concrete
TL;DR: In this article, the effects of using supplementary cementing materials and recycled concrete aggregates (RCA) in concrete, with emphasis on the ability of using high volumes of fly ash (FA) and RCA to reduce the environmental impacts of the concrete's production process without jeopardizing most of its long-term durability characteristics.

The past and future of sustainable concrete: A critical review and new strategies on cement-based materials
Jorge de Brito,Rawaz Kurda +1 more
TL;DR: A global and extensive review is made here to provide an overall view of concrete sustainability in all possible paths and to open the minds of the readers to the vastly unexplored world of “green concrete”.

Environmental assessment of green concretes for structural use
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.

Mohammed Fouad Alnahhal,U. Johnson Alengaram,Mohd Zamin Jumaat,Fuad Abutaha,Mamoun Alqedra,Ramappa Ramesh Nayaka +5 more
TL;DR: In this article, the authors present an experimental investigation on the durability properties and carbon dioxide (CO2) emissions of concrete developed using waste products, which consists of recycled concrete aggregate (RA) as a complete coarse aggregate replacement and rice husk ash (RHA), palm oil fuel ash (POFA) and palm oil clinker powder (POCP) were used as replacement materials for cement at levels up to 30%.
Journal ArticleDOI
Influence of recycled aggregates and high contents of fly ash on concrete fresh properties
TL;DR: In this paper, the fresh properties of concrete with supplementary cementitious materials (SCM) and recycled concrete aggregates (RCA), with emphasis on the feasibility of using high volumes of fly ash (FA) in RCA concrete, were presented.

Influence of recycled aggregate on fly ash geopolymer concrete properties
TL;DR: In this article, the effect of recycled aggregate on strength and durability of fly ash based geopolymer concrete was investigated. But the results showed that the use of high sodium hydroxide concentrations of 12 and 16 M resulted in better performances both in strength and resilience than that of 8 M.

Shear strength of recycled concrete beams
TL;DR: In this article, the authors report on the shear behavior of concrete made with recycled concrete aggregates and compare it with conventional concrete and two concrete mixes (conventional concrete and recycled concrete with 50% of recycled coarse aggregates).
