Abstract
This research included the ability to using the natural aggregates of quaternary deposits for the Lower Zab River terraces at Alton Cobri-Kirkuk Governorate / Concrete Works. The results of the engineering and laboratory tests of the natural aggregates and the return, which are geologically belonging to Quaternary deposits sediments showed that they are suitable for use in concrete work and investment for the establishment of suitable quarries in order to conform to the Iraqi and international standards. The rough and comprehensive aggregates with a maximum size of 40 mm can be used for natural aggregation immediately after washing and screening of concrete after increasing the ratio of fine aggregates to rough aggregates during the concrete mix process. As for aggregates The back of a more general gradation of the requirements of the limits of the gradient medium and soft global British standard specification and the marked increase in the size of 0.3 mm sieve match attribute to washing the exposed natural aggregates due to sites and models aligned to the River Zab down operations. works after increasing the ratio of fine aggregates to rough aggregates during the concrete mix process..
