DURABILITY PROPERTY OF FLY ASH, QUARRY DUST AND BILLET SCALE BRICKS

This paper investigates the durability of bricks produced from industrial waste like fly ash, quarry dust and billet scale when immersed in salt and acid solution contrasts from the conventional bricks. In this study, durability test was done by immersing the bricks in 1% by weight of sulphuric acid (H2SO4) and 3.5% by weight of sodium chloride (NaCl) for 28 days. The ratio of the compressive strength of the bricks immersed in salt and acid solution to the bricks immersed in water is expressed by the corrosion resistance. The change in mass of bricks and the visual inspection were assessed in this study. Results showed that the corrosion resistance was significantly increased and the weight was also increased. Besides, bricks developed from industrial waste in this study exhibited no any trace for erosion when exposed them in an aggressive environment through visual inspections. Therefore, the bricks developed in this study can be used in place of conventional bricks and they can be utilized in an aggressive environment.
