Abstract
In this research, (192) concrete cubes were taken from different concrete mixes incorporating coarse and fine aggregate from four different sources with two types of cement; Iraqi cement & Turkish cement. The compressive strength of these cubes was examined to know the most suitable materials to product good concrete for use in the projects of Tikrit University. The results indicate that, the aggregate from Al-Mosul source gives compressive strength higher than the aggregate from other sources. The Turkish cement gives compressive strength higher than that given by Iraqi cement.
