Wastepaper accounts for a large volume of the waste generated by the country. This research study was conducted to create functional Cement – Bonded Board using wastepaper as aggregates. In the research presented, the physico – mechanical properties of the experimental Cement – Bonded Board (CBB) were tested and compared to the standards.
Three types of tiles were created containing 15%, 25% and 30% of wastepaper to cement by mass. The mixtures were molded and pressed with a 1 Kg weight for 24 hours. After removing the weight, the tiles were cured for 28 days before testing.
The water absorption, fire – resistant property, and compressive strength of the tiles were tested. The water absorption property of the tiles were comparable if not better than some experimental. It absorbs 10.63% water at the maximum and is fire-resistant exposed at 650°C for three (3) hours. It can withstand 9.53 KN up to 10.37 KN of load. Its compressive strength is comparable only to CBBs employing fibrous residues and is only a tenth of the compressive strength of concrete. However, the values obtained were comparable to most CBBs using fibrous residues as aggregates. As such, the experimental tiles are considered for non-load bearing applications such as partition walls.
The experimental tiles can be further tested for its application if function and costing can surpass that of conventional CBBs. The problem of recycling waste has already been solved and at the same time, cement – bonded board had been produced.
