【 摘 要 】

After the success of experiments using the Iraqi Bentonite in the work of drilling oil wells as an alternative to the importer Bentonite which encouraged its use as an alternative for the work of civil excavation, such as diaphragm walls, drilling, bore pile, barriers, dams and tunnels. By changing the mixing and drilling method followed in the work of oil wells, which requires the conduct of many experimental mixtures to reach the optimal mix. Benefits were getting from the previous experiments conducted on such type of Bentonite were used by the General Company for Geological Survey and Mining and Ramadan Mubarak Company one of the formalization of the Ministry of Housing and Construction; in which the optimum mix was reached, the method of mixing was determined, the components and quantities of the materials included in the preparation of the optimal mix were determined in 1m3 of water for mixing time of 5 min. This study was supported by the results obtained by the Geological Survey and Mining Company, which relied on the use of (NaOH) as an alternative to the active calcium-centric (CMC) of Bentonite, which is considered to be one of the most expensive materials. This paper will be a good index for all concerned with implementation of civil excavations and field works.
