Ten samples of different compositions were fired at a temperature of 1200ºC. . Geopolymer bricks that are prepared by partial binder substitution, water cooled slag, with clay brick waste (grog) in a ratio ranging from 0 up to 100%, and with a fine sand ratio of 15% of the total weight. Grog is not necessary, although it does improve the workability of the clay, plus reduces shrinkage, cracking and warping. The starting raw material and the generated geopolymer specimens produced by different geopolymerization reaction conditions have been characterized using . Without sand there is very little airflow. concrete/grog/hydrated lime in the ratio of (40/50/10, wt. That's the general rule but there are 2 or 3 exceptions.
