"Strength, Toughness and Durability of Extruded Cement Boards with Unbleached Kraft Pulp"

Abstract

The paper evaluates the use of extrusion technology for the production of cement boards with unbleached kraft pulps. The experiment fabricated cement boards reinforced by both hardwood and softwood pulp of different percentages by using an auger type lab extruded. The moisture content, water absorption and density of all batches were measured. To investigate the strength, the toughness, the anisotropy, the age effect and the resistance to natural weathering as well as the freeze-thaw cycling, the flexural response of the cement boards was used.
