The purpose of this research work was to develop innovative environmental friendly building brick and study their performance, particularly on wetting and drying cycle. To understand the relative significance of these results geopolymer building brick with which different Na2O/(Al2O3+SiO2) has been manufactured. Geopolymer building brick has been manufacture by using highly alkaline solution and an aluminosilicate source. During this research work (230 × 110 × 75 mm) size building bricks were manufactured. After 25 days of atmospheric curing the bricks attained a crushing strength of 10 to 12 Mpa. Then the bricks were submerged in water to observe the effect of wetting and drying cycle on strength of brick. Results comprised that even after 10th cycle, there is no specific deterioration in the crushing strength of brick.
Keywords: Fly ash, geopolymer, wetting drying cycle & atmospheric curing.
