Abstract:
Fired-clay products such as bricks, tiles and pavers, are made in large volumes for use in a variety of
construction applications throughout the world. A significant proportion of them ends up being a waste
product either during their production process or the demolition of buildings. High pressure steam curing
or autoclaving has proven extremely versatile for the manufacture of cement-based building products
incorporating waste materials such as fly-ash and blast furnace slag. The nature of hydration products
in an autoclaved cement based system incorporating different amounts of finely ground brick
waste was investigated by means of thermal analysis and XRD, and is the subject of this paper.
