Some disadvantages associated with conventional brick masonry are: high cost of construction, lower compressive strength and less durability. In order to resolve these problems, a new technique of constructing walls using large size baked clay blocks is introduced. For this purpose, clay blocks of size 150 mm × 300 mm × 1980 mm were cast at a pressure of 6 MPa, and fired at a temperature of 700℃. In this paper, compressive strength and tensile strength of baked clay were investigated in order to find its suitability as a walling material for low cost houses. Cubes of 150 mm sides were tested in compression and the beams were tested in flexure. The results showed that compressive strength of baked clay cubes was found to be 10 MPa and tensile strength, in terms of modulus of rupture, was found to be 2.3 MPa. Since the baked clay blocks are larger in size than traditional bricks, it is inferred that the blocks could be used as a cheaper and stronger walling material.
