Recycling of demolition waste of Al Hawija area located within Kirkuk governorate

This work consists of an evaluation and an approach to reuse the demolition waste (DM) resulting from the military operations of the Hawija area located within the Kirkuk governorate. Several laboratory tests on the residues were conducted: gradient and unit weight, corrosion, CBR, and resistance tests. Moreover, cement was added to upgrade these properties. The UCS compressive strength was carried out on models of (DM) to study the strength by compacting a mixture of demolition waste stabilized by (2, 3, 4, and 6) % of cement at the optimum moisture content (ωopt)and maximum dry unit weight (γdmax) of 20.3 kN/m3. Results indicated the possibility of using these materials successfully according to the test specification ASTM D1883-2005, AASHTO T180-2010, ASTM D1557-2002. Cement addition led to an increase in the level of materials used in roads as sub-base layers, and the best percentage of 4% could be added to (DM) to meet the minimum resistance requirements.
