Improved storage and handling of fine recycled concrete aggregates by accelerated carbonation: towards a quantification method

Vogt S., Koeniger L., Brück F., (Corresponding) Weigand H.
Topic: 
Construction and demolition waste
The fines fraction generated by crushing of concrete waste for production of recycled concrete aggregates amounts to 40 - 60 mass-%. Technically, fine recycled concrete aggregates (0 - 2 mm, fRCA) may be employed as a sand substitute in new concrete products. This is, however, hampered by the...Read more

A study of the properties of alkali activated cement concrete with potassium carbonate activator.

(Corresponding) Mavroulidou M.
Topic: 
Net Zero emission transition
Alkali-activated cements (AAC) have recently attracted the vivid interest of the civil engineering industry as promising innovative alternatives to Portland Cement (PC) which is responsible for 8% of anthropogenic CO2 emissions. In this context, this paper studies concrete produced using potassium...Read more
