Abstract

The artisan clay bricks in Uganda are characterised with low strength, erosion, tiny cracks, lime pop out, warping, efflorescence occurrence and high-water absorption. The raw clay and artisan burnt clay brick samples were collected from artisan brick making places (sites) from Eastern, Central and Northern Uganda. The sampling was done using IS-5454 procedures. Testing was carried out for; water absorption, mineral percentage investigation in natural and purified clay in terms of SiO₂, Al₂O₃, Fe₂O₃ & CaO, compressive strength of the artisan clay unit, improved chemical composition artisan clay units from purified clay and improved molded bricks from raw clay. Results indicated mineral requirements for manufacturing bricks was not satisfactory, for artisan bricks, they had very low characteristic strengths of 0.63N/mm² for Lira and 0.38N/mm² for Mukono. Refining and change on molding process was done and the raw clay structure shifted to the positive side of the required mineralogy. Fired bricks on testing gave higher characteristic strengths of 2.2 (improved chemical composition bricks) and 3.3 (improved molded bricks) for Lira, 5.12 (improved chemical composition bricks) and 2.62N/mm² (improved molded bricks) for Mukono, slight efflorescence and low water absorption. Studies therefore recommend that the artisan do include both refining processing and constant force kneaded clay pressing in the manufacturing process.
