摘要：In recent years there has been a great deal of interest and support worldwide in using construction anddemolition waste as ceramic as well as clay brick wastes (grog) for production of aggregate material which can then bereused for road base courses or construction backfill materials, and other engineering applications. However, they canalso be employed as supplementary cementitious materials or even as raw material for alkali-activated binder forproducing more valuable binders that can be applied in various building applications. Geopolymer bricks prepared bypartial binder substitution of ceramic by clay brick wastes in the ratio from 0 up to 100 %, while the used fine sandwas in the ratio of 15% from the total weight, also sodium hydroxide activator was used in the ratio of 8% of the totaleight. The properties of the produced geopolymer bricks have been studied through measurement of compressivestrength, water absorption, FTIR, XRD and SEM imaging. Results demonstrate the possibility of using alkali activatedceramic and grog materials in producing heavy duty building with compressive strength values more than 35 MPa up to20% grog increase, however further increase results in lowering strength values as a result of increase of crystallinecontent and sufficiency of the used activator to dissolve all the crystalline fractures.
