this research studied the manufacture of Portland oil shale cement (OSPC) from one of the wells located in the south-east of the Aleppo city which far (103 Km) from Khanasser - Rjam Al Sawan, The area of Location where nearly (150 Km² ), By replacement the limestone in the mix of raw materials for the manufacture of cement with local oil shale in different rate: % (10-20-30-40-50-60-70-80-90-100). Then the feasiblity of burning and the technicall properties of prepared cements were studied. the results showed that replacement (80-90-100) % Of limestone with local oil shale, Lead to C in the burning temperature of the raw materials which used in the production of Portland cement,and As well as reduce the amount of time (25%) to complete the burning process. And that reduce the consumption of required fuel for the burning process, thus, Keeps the environment clean, and remain within the permissible limits according to the European standard (EN 197-1).
