Abstract
The Autoclaved Aerated Concrete Powder (AACP) - a traditional construction
material - has reached its service life in many dated buildings. Utilizing recycled
AACP powder as raw material for producing artificial aggregates can be a potential
solution as alternative to its landfill. This paper investigates the effectiveness of
utilizing high volume fly ash mortar as binder to produce cold-formed aggregates.
The weight ratio between cement and fly ash is set to be 50%, while aggregates
made from 100% cementitious binder are also prepared for comparison purposes.
While 10-20% binder weight ratio is not effective for overall pelletization of the
particles, the aggregates made from higher binder percentage reached early 90%
production efficiency. However, further investigation into the issue of high-water
absorption of artificial aggregates is necessary to improve their overall quality.
