Cement mortar is a heterogeneous material obtained by mixing cement paste (binder) with aggregates (filler), the later constituting more than 80% of the cement mortar. Cement mortar is a macro-material strongly influenced by addition other materials such as iron oxide. One of the most important properties of hardened cement mortar is its compressive strength, which can be quantitatively measured. In the present research the effect of iron oxide particle size on the compressive strength of cement mortar was studied. The particle size of iron oxide considered as (0.25 mm, 0.50 mm, 1.00 mm, 1.50 mm, and 4.00 mm). The compressive strength of hardened cement mortar samples were tested after 28 days of completion of curing. Results showed that the compressive strength of the cement mortar using a various iron oxide particle size increased with decreasing the particle size. Maximum increasing in compressive strength was about 20%, the addition of iron oxide to concrete with suitable fine iron oxide particle size will enhance the compressive strength of cement mortar due to the less formation of porosity
