| Popis: | Bricks are the most frequently used building units in residential and commercial construction in Iraq. This paper presents a comparative study of the physical properties of perforated clay bricks manufactured by five different factories: three of brick samples are local, with the other two being imported. Thirty specimens were tested for each factory for a total number of 150 bricks. Brick samples were randomly selected from the local market and then tested according to Iraqi specifications 24/1988 and 25/1988. The tests results showed that water absorption was lower in the local samples (13.7% minimum) than the imported ones (22.2% maximum), while efflorescence rates for both local and imported samples ranged from light to medium. The compressive strength of one local (about 29 MPa) and both imported samples (about 12 MPa) met the specifications, while the other local samples demonstrated lower compressive strength than the specifications. Overall, based on the adopted specifications, only one local sample was classified as class A, with the other samples did not meet requirements. |
