Abstract:
Fired-clay products such as bricks, tiles and pavers, are made in large volumes
throughout the world and widely used as construction materials. A significant proportion of
themend up being a waste material during either their production process or the demolition
of buildings. High pressure steam curing or autoclaving is a proven and versatile method for
utilising supplementary cementing materials such as fly-ash and blast furnace slag for the
manufacture of cement-based building products. In this investigation, autoclaving has been
used to treat blends of ordinary Portland cement with different amounts of ground brick
waste. Our experimental data demonstrate the viability of this waste to be used by the
construction industry as a supplementary cementing material. The paper presents results of
salientengineering properties in relation to microstructural characteristics.
