Determining the Physical and Chemical Properties of the Soils in Babylon and Al-Qadisiyyah for Manufacturing Clay Bricks
The research included conducting a study of eight selected soil Stations in the Babylon and Al Qadisiyyah. The main target of the research is to study the physical, chemical, and compressive strength properties of these soils and their suitability for manufacturing ordinary clay bricks. It was found through the evaluation of the soils of the studied samples that their physical properties ranged as follows: the water content (13.52-31.88%) and the grain size analysis of the proportions of sand, silt, and clay as follows: (5-27%) (38-48%) (33-47%), respectively. The values of the Atterberg limits ranged as follows: the plastic limit ratios (13-21%), liquid limit (34-49%), plasticity index (13-28%), and the specific gravity ranged between (2.43-2.67). As for the chemical properties of the studied samples, they consist of a lot of silicates, carbonate calcium, and calcium oxide. Studied samples were characterized by water absorption 15-24%, and the efflorescence is varied from medium, low to nil. The soil samples are consequently considered as a suitable material for the manufacture of ordinary bricks in grades A and B based on Iraqi Standard specifications No. 25.
