The need for maximum disposal of wastes and conservation of scarce resources or materials into useable building materials need to be underscored. Therefore, this study attempts to evaluate the use of polythene bag wastes in the building industry. The polythene bags waste (pure water sachets bags) were collected in dumping sites in Yola metropolis and were manually shredded to about (5 x 10) mm sizes. Fired Cement clay (FCC) bricks incorporating the polythene waste were produced at a mix ratio of 1:8 and water/cement ratio of 0.5. Samples were tested for compressive strength at 7, 14, 21 and 28days hydration period while the water absorption and thermal conductivity test were evaluated at 28 days hydration period. Result of the compressive strength for the FCC Bricks at 28 days hydration period was between 0.00 and 2.33N/mmsup2/sup, with 10% FCC having the highest compressive strength and least water absorption values of 2.01N/mmsup2/sup and 85 Kg/mmsup3/sup respectively. The compressive strength and thermal conductivity of all sampled FCC bricks decrease with increase percentage content of shredded polythene bags waste. The study found that thermal conductivity values of the FCC bricks was in the range of 1.48w/mk and 1.8w/mk. The study therefore recommends 10% FCC as suitable for use in areas where thermal transfer and rising dampness is of interest. Furthermore, the study concludes that reuse of the polythene bag wastes as building material or resources will help in reducing environmental hazards.
