Brick is the oldest building material. It is a standard sized weight bearing unit. The earliest bricks were formed from clay or mud and sun dried. During 2007 the new flyash bricks were created using by-products from coal plants. Recently, due to the ever-increasing demands of the construction industry, clay extraction is posing a serious environmental problem. As engineers, it is our responsibility to look for an alternate solution which is both efficient and environmentally sustainable. One such alternative is to substitute clay in bricks with pozzolanic industrial by-products. Pozzolona ns are inert cementitious materials rich in clay and alumina. Use of an alkaline activator solution promotes the reactions in the pozzoloanic material and activates the cementitious property. In the present work, geopolymer bricks containing fly ash (70 percent by weight), ground granulated blast furnace slag (30 percent by weight), natural sand and alkaline activator, have been manufactured. The alkaline activator used was a combination of sodium hydroxide and sodium silicate solutions. Further, the suitability of rice husk ash (RHA) as a puzzolonic material has been tried by casting bricks with different percentages of fly ash and RHA. Fly ash has been replaced with RHA at increments of 20 percent by weight of binder in bricks. The bricks were cured under ambient conditions for 28 days and laboratory tests have been conducted to ascertain the physical and mechanical properties of the bricks. Based on the test results, a suitable percentage of RHA in geopolymer bricks has been suggested
