| Abstract | ||
| The results of grain size and petrographical analysis and some engneering propereties for clayey sediments withen Sheranish,Kolosh and Gercus Formeation , north & northeastern part of Iiraq , after compared with iraq specification No, 25, for the year 1988 , it is possible for using some of these sediments in pottery bricks mainufacturing after treatment with dilute acid and mixed with river sand percentages (Khazer sand) enrichment with silica, pass through (0.6mm seive) which valied regionally. The processes of washing the clay with some diluted acid which improved and forming proprieties. The clay of Gercus formation in Sheakhan region contain a lesser percentages of Gypsum and Carbonete salt than that of Dohouk region. The clayes of Gercus formation in Shekhan and Dohouk region contain a lesser percentages of salt than that of Sheranish & Kolosh , which have relatively better characheristic , so that the pottory bricks which manufactured from this kind clay are characterized by a relatively good compressive strength , lakes of cracks with good plasticity and conform , corresponding with iraq standerd No , 25, for the year 1988 class (B&C) after certain additions and treatments. | ||
