EFFECTS OF WOOD-PULP FIBERS ON THE MECHANICAL PROPERTIES OF CEMENT COMPOSITES

The application of pulp fiber in cement paste has been under consideration to improve the bearing capacities of the cement composites. Cement composites made by various types of fibers have distinct properties regarding the stability and resistance in dissimilar environmental conditions and applied loads. This behavior depends on four main factors: a) fiber type, b) mixture percentage c) fabrication manner, and d) additives. In this work, to distinguish the flexural behavior of fabricated composites with wood-pulp cellules fibers, the experimental samples designed and tested. The samples made with these fibers were compared with the no-fibrous control samples for their flexural strength and modulus of elasticity. Moreover, to characterize the microstructure properties SEM micrographs were analyzed. The results showed that the application of fibers had suitable effects on the improvement of the flexural strength related to the amount of used fibers.
