Abstract: In the present investigation attempt has been made to improve the strength of the black cotton soil mud bricks mixed with different content of lime by reinforcing the geogrid. The soil is collected from Naragund area of Bagalkot District. The circular (100mm diameter and 200mm depth; 150mm and 100mm depth) and rectangular (200mm x 100mm x 100mm) mud bricks are prepared with soil treated with 10, 12, 14 and 16 percent lime with the geogrid reinforcement at the middle depth of the brick. The compressive strength of the mud bricks is obtained by laboratory compression test apparatus. Considerable improvement in the compressive strength is observed in rectangular mud bricks with14% and 16% of lime content reinforced with geogrid and for circular mud bricks, the maximum compressive strength is observed at 12% lime content with geogrid reinforcement
