Type: conference-paper
Abstract: The durability and stability of masonry structures throughout usage can be affected by producing process, material properties and environmental conditions such as moisture hence finding out the factors affecting durability of clay bricks is vital so as to produce bricks of high strength which will absorb less water. The effect of stabilizing clay for the production of interlock bricks using lime at various percentages was investigated. Soil type used in the production of interlocking bricks was A-6 soil using the AASHTO system of soil classification. Maximum reduction in Liquid Limit and Plastic Limit of the clay material was observed at 8% addition of lime. The Specific Gravity rose from initial of 2.71 at 0% to 2.85 at 10% addition of lime. The maximum reduction of Average Water Absorption (AWA) of clay modified with lime was observed at 8% and the value of AWA recorded was 13.3%, which brought the clay brick to the first class designation from the second class designation of 0% of lime addition. The compressive strength reduced at 8% for all the sampling period of 28 days, the compressive strength test is lower than specification as such the bricks can be used in non-structural member in construction.
