Calender extrusion of cement mixtures for sustainable composite production

This research investigated as a sustainable production technique, the application of calender extrusion in the production of cement fiberboards. Use of the technique was successful for the production of non-structural building elements. The properties of the produced composites are discussed in this paper. Glass, polyvinyl alcohol (PVA), and polypropylene (PP) fibers were used. The research involved an experiment to examine the mechanical properties and microstructure of the composites. The experimental results showed that calender extrusion may be a promising method for sustainable production of thin and wide cement composites. Various forms of cement composites can be produced with this method as well. Results indicate that the mechanical properties of cement composites produced with this method are dependent on the processing direction. Processed composites have adequate screw head pull-through and freeze-thaw resistance. Higher MOR values were obtained for water cured specimens compared to air cured ones.
