We investigated the effects of amount of antioxidants variability on selected mechanical and physical properties of wood plastic composites. Recycled high density polyethylene (rHDPE) and natural fibers were compounded into pellets by compounder, then the pellets were extruded using co-rotating twin-screw extruder and test specimens were prepared by hot and cold press process. From the study, samples with 0.5 wt% of antioxidants produce the highest strength and elasticity of composites. The effect of antioxidants presence on water uptake is minimal.

The effect of different wood flour sizes on strength and dimensional properties of wood-plastic composites were examined. Wood flour of different particle sizes viz; 1.00mm, 2.00mm and >2.00mm were compounded with recycled low-density polyethylene (LDPE) at different wood/plastic ratio of 1: 1, 2: 3 and 3: 2. The results obtained showed that wood flour size > 2.00mm has the highest MOR and MOE values of 1.206N mm-2 and 2484.72Nmm-2 while wood flour size of 1.00mm had the lowest MOR and MOE values of 0.505Nmm-2 and 2195.89Nmm-2 respectively. Also the results of the physical properties showed that wood flour size of 1.00mm had the lowest thickness swelling percentage with mean values of 0.28% and 2.08% while water absorption percentage has mean values of 0.91% and 10.58% after 2 hours and 24 hours of water immersion respectively. It was observed that wood flour size of 2.00mm and particle size >2.00mm had the highest thickness swelling and water absorption percentages. This showed that strength properties of wood plastic composites increased with increased particle sizes whereas its dimensional properties increased with decreased particle sizes. The results of analysis of variance carried out on mechanical and physical properties showed that particle sizes and wood/plastic ratio had a significant effect on the mechanical and physical properties of wood plastic composites (p 0.05).

Magnesium slag is an industrial waste residue produced in magnesium smelting. Its chemical composition is similar to Portland cement and has potential activity. After the magnesium slag is foamed, it can be made into a new type of lightweight material, and its forming, mechanical and physical properties were closely related to dry material formula, water-cement ratio and foaming agent amount. In this paper, experiments were carried out to find the ingredients and processes suitable for the forming of foamed magnesium slag, making it have certain mechanical and physical properties at the same time.

Magnesium slag is a kind of industrial waste with the similar chemical composition to silicate cements, which is of hydration activity to some extent. However, the hydration activity of magnesium slag is much lower than that of traditional silicate cements. Through the method of carbonization, this experiment enhanced the hydration activity of magnesium slag, so that the strength of magnesium slag products can meet the requirements of structures together with certain mechanical and physical properties as well.

This review deals with recent works on the process and technological aspects of wood-plastic composites (WPCs) manufacturing.The term WPCs relates to any composites that contain plant (including wood and non-wood) fibers and thermosets or thermoplastics. Recent progress relevant to wood-plastic composites has been cited in this review. This articleintended to outline the results presented on wood-plastic composites focusing on process and technological aspects such as raw materials, fabrication, mechanical, physical, thermal, and morphological properties. The manufacturing process of WPCs is an important aspect of WPCs production. Manufacturing methods like compression molding and pultrusion have some limitations. Extrusion and injection molding are the most widely used manufacturing processes in WPCs due to their effectiveness. Recent developments dealing with WPCs and the use of different kinds of nanofillers in WPCs have also been presented and discussed. Nanoclays are widely used as nanofillers in WPCs because they represent an eco-friendly, readily available in large quantity, and inexpensive filler. WPCs are finding applications in many fields ranging from the construction to the automotive industry.Keywords: additive manufacturing, adhesion, fabrication techniques, mechanical and physical properties, wood-plastic composites
