Microbial carbonate precipitation for the improvement of quality of recycled aggregates
High water absorption is the main drawback of recycled aggregates which greatly hinders the re-use of them in concrete production. In this study, bio-deposition treatment, based on bacterially induced CaCO3 precipitation, was applied to improve the ...

SEM image analysis in permeable recycled concretes with silica fume. A quantitative comparison of porosity and the ITZ [PDF]
Recycled aggregates (RA) from construction and demolition can be used in permeable concretes (PC), improving the environment. PCs have a significant porous network, their cement paste and the interaction between the paste and the RA establishing their ...

ABSTRACT Circular economy (CE) is increasingly adopted by the manufacturing industry to decouple economic growth from environmental impacts by optimizing resource use and minimizing waste generation. Nevertheless, circular manufacturing often triggers systemic responses that diminish or offset their potential environmental gains, resulting in the so ...

Expansion and strength properties of concrete containing contaminated recycled concrete aggregate
In the Middle East region, interior walls of buildings are mostly plastered with gypsum. Thus, the demolition wastes are probably gypsum contaminated, which may lead to internal sulfate attack in new concretes containing recycled concrete.
