Abstract
This research presents a comparison study for physical properties between Iraqi and
Iranian perforated clay bricks. 300 samples of perforated clay bricks are randomly
selected from the production of five Iraqi factories and five Iranian factories which
are available in local markets ( 30 bricks from each factory ). All samples are selected
and tested by standard methods according to Iraqi standard specification No. 24/1988.
The results of the tests are evaluated according to the requirements of the Iraqi
standard specification No. 25/1988. The physical properties that have been tasted
(according to the requirements of Iraqi specifications) are; general appearance,
deviation of dimensions from standards, concave and convex, absorption,
compressive strength and efflorescence. The results show that Iraqi bricks are better
than Iranian bricks in deviation of dimensions from standards and absorption while
Iranian bricks are better than Iraqi bricks in general appearance, concave and convex,
compressive strength and efflorescence. When all tasted properties are evaluated with
general requirements of Iraqi specifications for general evaluation, results show that
Iraqi bricks are better than Iranian bricks and all samples of bricks can be classified
within either class B or C and no unite within class A.
