Concrete from deconstruction can have a second life in the form of recycled concrete aggregates (RCAs). They unfortunately poor properties (high porosity and water absorption coefficient (WAC)) with respect to natural aggregates. Accelerated carbonation was implemented improve RCA increase their use by storing carbon dioxide (CO2) cement matrix thereby reduce environmental impact. This paper ai...

Geopolymer concrete is a more environmentally friendly alternative than conventional because its production does not need cement. Instead, waste materials such as fly ash, rice husk slag, etc. are used. This research studies the effect of activator concentration (6–10 M), curing temperature (40–80 °C) and incorporation ratio thermally mechanically treated recycled aggregate (0–100%) on changes ...

The construction sector is one of the most energy-intensive and raw-material-demanding human activities and, hence, contributes a significant share greenhouse gas emissions. As matter principle, making “greener” main challenges for policy makers, private companies scientific community. For this reason, promising actions based on recycling Construction Demolition Waste (CDW) converting them into...
