Mechanical Properties of High Density Polyethylene/Cement Kiln Dust Composite Natural Monomer by Wael Elhrari* in Crimson Publishers: Peer Reviewed Material Science Journals
A viable solution for reducing the negative environment impact of cement kiln dust (CKD) is to combine with polymeric materials to produce composites materials for many applications in different purposes. In this work, an attempt to investigate the addition of CKD as filler with different load to High density polyethylene (HDPE), also the effect of polyethylene glycol (PEG) as compatibilizer on mechanical properties of the polymer composites. HDPE/CKD composites with various CKD content (0,2,4,6, and 8wt%) samples were prepared by melt extrusion followed by injection molding. The effect of adding 2wt% of PEG on mechanical properties of the composites were studied. Tensile strength, impact resistance and, surface hardness was investigated. The results showed improve in tensile strength and elongation at break (%) of polymer composites with 2wt% CKD and reduction in the elastic modulus which attributed to that polymer composite become more ductile and tough. The addition of PEG as compatibilizer showed a significant improvement in mechanical properties that were clear in tensile and impact strength of the polymer composites.
