“…Much research has been carried out on the utilization of fly ash for bricks (Takegawa 1996, Kumar 2002, 2003, Lingling et al 2005, Cicek & Tanrýverdi 2006, Lin 2006. These studies were based on the fly ash available from a particular power plant, and the properties of the product obtained were dependent on the quality of the ash/coal (Ayoko et al 2005). In addition to superior conventional properties, fly ash/clay bricks have the advantage of being the usual red colour, which enhances the acceptance of the product to users (Das & Segaran 2005).…”
