Aim of this study was to introduce an eco-friendly, low cost and durable clay bricks with partial substitution of Cow Dung Ash (CDA). Five types of clay brick, consist CDA percentages 0, 5 10, 15 and 20% to the total weight of mixture, were manufactured by employing traditional method of dimension (18.5×8.5×6.5) cm3. The clay and CDA were well mixed with the addition of sufficient amount of water to form a good workability. Green molded bricks were allowed to dry under sunlight for two days and then fired in the traditional brick kiln. Physical properties of the burned red bricks were then tested and analyzed with Sri Lankan and British Standard Specifications. The average density, water absorption, compressive strength and flexural strength for 10% Cow Dung Ash (CDA) are 1447 kg.m-3, 17%, 150 and 0.82 respectively. These physical properties were compared with the standard brick purely manufactured from clay. From the results, clay-CDA bricks are obviously superior to the control brick; those are available in the Eastern region markets.
