The aim of this study work presented in this paper is to assess the quality of 1st class burnt clay bricks manufactured in 5 (five) different clay brick manufacturing industry in the Jorhat district of Assam. This study also attempts to understand the entire manufacturing process that is followed in clay brick manufacturing. 20 bricks samples were randomly collected from each of the 5 (five) clay brick manufacturing industries namely NBF, BBB, SBI, MAYUR and MAK to determine their physical and mechanical properties. In this regard, four principal quality tests such as Water absorption test, Efflorescence test, Compressive strength test and Dimension test was conducted and the test results were compared with IS recommended values. From the water absorption test, it was found that NBF, SBI and MAYUR met the IS requirement. The efflorescence test results for all the brick brands were found satisfactory as per IS Code of clay burnt bricks. The compressive strength of (14.72 - 17.82 N/?mm?^2) were within the class designation of burnt clay brick. The brick samples were observed to have length, width and height within the tolerance level. This study will be helpful to the researchers, policy makers and concerned authorities to perform the quality analysis test of 2nd and 3rd class clay bricks in future.
