Abstract
This work studies the physical properties of ceiling boards produced from waste paper. The ceiling boards were produced using waste paper, fire retardant and cement of varying quantities. The compression of the boards was done using hydraulic press. From the results, it was observed that the ceiling board produced with 100% fiber from waste paper met with the commercial fiber ceiling board standard to about 4/7 of both calculated and measured properties; giving 415kg/m3 density, 660kpa compressive strength, 809 hardness and 2.5KJ impact strength. The trend of quality of boards produced decreased as follows: 100>70>90>80>60.
