MOISTURE EFFECTS ON FLEXURAL PERFORMANCE OF WOOD FIBER-CEMENT COMPOSITES

An experimental study is reported, which attempted to assess the effects of moisture condition on the flexural strength and toughness of wood fiber-reinforced cement composites incorporating 1% and 2% mass fraction of kraft and mechanical pulps. Comprehensive sets of replicated flexural test data were evaluated statistically using the analysis of variance procedure. The effects of wood fiber-reinforcement on some physical properties of cement mortars in the fresh and hardened state were also investigated. It was found that wood fiber reinforcement led to increased water requirement, setting time, void content, and water absorption capacity of cementitious materials. Specific gravity was reduced in the presence of wood fibers. These and other findings are presented and discussed.
