Abstract Geopolymers are inorganic polymeric materials They are conventionally produced by reacting solid alumino{uF02D}silicates with a highly concentrated aqueous alkali hydroxide . In the present thesis ground waste produced from firing clay bricks (homra) and slaked lime (Ca(OH)₂) were used to prepare geopolymer bricks. The parameters affecting the physico{uF02D}mechanical properties of produced geopolymer bricks were then studied. These are: fired clay brick waste particle size, mixing water mass percent, amount of Ca(OH)₂ and NaOH used, used. It was found that geopolymer bricks compatible with ASTM C 62 for normal duty building bricks could be prepared by mixing waste homra ground to 0.075 mm with 8 % solid slaked lime, 0.5 % NaOH and 28 % water |
