According to the needs of Naenava Governorate for manufacturing building fired-bricks the, this work was conducted to evaluate the suitability of the exposed claystones within Injana and Mukdadiya formations in Al-Kind Hills region for such industry.

Twenty three clay samples were subjected to crushing, quartering, dividing, and then testing to indicate their chemical, physical and mineralogical properties.

The samples were extruded to have dimensions of (2.5 x 3.85 x 7.5) cm, which were then dried at room temperature for 48 hr and for 24 hr at 110° C, using laboratory oven.

Different variables were studied including particle size reduction of representative sample for the whole region (+ 150 and – 150) µ, adding river sand (10 and 20) %, and then changing in firing temperature (700, 750 and 800 º C).

The firing of the brick samples were carried out at a certain program; for 2 hr socking time.

The resulted samples were tested for their physical, mechanical and mineralogical properties and then the results were compared with the requirements of the Iraqi Standard Specification No.25, 1993.

The results indicated that the claystones under study were suitable for brick manufacturing.

The test results of some samples fired at 800 º C were found in accordance with the mentioned standard specification.
