Abstract
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
