In this research, the possibility of producing building bricks from the shale reserves of Lorestan province has been investigated. Sampling was done in six different areas, and after conducting XRF tests, one sample was selected for brick production. 10 different combinations of bricks with different percentages of shale were made from the selected sample. Compressive and bending strength and water absorption tests were performed on the manufactured samples. The results of the tests showed that with the increase in the percentage of shale, the amount of water absorption increased, so that the samples consisting of 90 to 100% shale had 14.8% water absorption. The sample containing 10% shale has a water absorption rate of 11.1%. Also, the results showed that increasing the percentage of shale decreased the compressive and bending strengths of bricks. The sample with the highest compressive strength, with a value of 27.2 MPa, corresponds to the sample containing 10% shale, while the compressive strength of the sample containing 100% shale is only 11.2 MPa. Based on the INSO-7 (Iranian national standard), the manufactured bricks are of good quality and can be used as building bricks and facing bricks in buildings.
