Abstract:
This research focused on utilization of bottom ash, the by-product from lignite coals combustion process. X-ray Diffraction (XRD) analysis indicated that the lignite bottom ash contains various minerals i.e. quartz, anorthite, and hematite. Such compositions suggested the bottom ash as a possible raw material in the production of lightweight clay brick (masonry brick). The bottom ash, used as clay replacement, of 20, 40 and 60 wt percent was mixed with gypsum powder (plaster mold waste from ceramic industry) and sodium silicate with the weight ratio of 1 to 2. Brick drying processes were carried out at temperatures of 40, 65 and 110 Celsius degrees for 4, 2 and 1 days, respectively, in addition to 30 min firing at 800, 900 and 1000 Celsius degrees. This research shown that the addition of bottom ash resulted in an increase of water absorption, while it affected to decreases in bulk density and compressive strength of the obtained bricks. Moreover, increasing of firing temperature resulted in decreased water absorption, nevertheless, the bulk density and compressive strength of bricks increased. Specimens with a bulk density of 1.16 g/cm3 and compressive strength of 2.54 MPa were obtained from the addition of 60 wt percent of bottom ash and firing temperature of 800 Celsius degrees
