Accelerated and natural carbonation of concrete with high volumes of fly ash : chemical, mineralogical and microstructural effects [PDF]

open access: yes, 2019
Today, a rather poor carbonation resistance is being reported for high-volume fly ash (HVFA) binder systems. This conclusion is usually drawn from accelerated carbonation experiments conducted at CO2 levels that highly exceed the natural atmospheric CO2 ...

Valorization of Crushed Fly Ash Brick Waste as a Low‐Carbon Binder for Sustainable Concrete Production

open access: yesAdvances in Civil Engineering, Volume 2026, Issue 1, 2026.
The construction industry significantly contributes to global CO2 emissions, with cement production being a major factor. Concurrently, large quantities of crushed fly ash brick (CFAB) waste accumulate due to manufacturing defects. In this study, CFAB powder was developed as a supplementary cementitious material (SCM) by partially replacing cement in ...
