Abstract
This study was conducted to investigate the potential of waste newspaper application in cement fiber board production. Cement fiber board were produced using three levels of waste paper fibers and two levels of calcium chloride as additive material. After making the boards, the Modulus of Rupture (MOR) and thickness swelling after 24 hours immersion in water were determined based on DIN 68763. The results showed that boards made with cement:fiber ratio 90:10 and 5% calcium chloride exhibited the maximum modulus of rupture and minimum of thickness swelling (TS) after 24 hours. The results also showed that additive material had positive effect on physical and mechanical properties of boards.
