Abstract
Lightweight interlocking brick is one alternative to replace conventional clay brick through combustion. This study relates to the design of the proportion of interlocking light brick mixtures as well as concrete sand and foam agent in various percentages and found the optimal percentage of foam agent by testing cylindrical specimens casted for 28 days compressive strength and finally testing each others lightweight brick shear strength lock in full scale model. The final report provided the results of investigative experiments in which compressive strength, water absorption and density were investigated using the optimal percentage of the proportion of foam agent, sand, cement, and aggregate mixture. The results of the experiment are compared to ordinary clay bricks. In conclusion, the concept of lightweight interlocking brick system has been widely used as a replacement of the conventional clay brick system where it has been utilized either as load bearing or non-load bearing brick system. The results show that the brick with foam agent is lighter, more durable aggressive environment and better strength for use in the walls of the building so that it can be mass produced by the brick industry.
