Utilization of waste spent alumina catalyst and agro-waste rice husk ash as reinforcement materials with scrap aluminium alloy wheel matrix

Abstract

In this study, an attempt was made to utilize waste products from industries to develop composite materials. In the present study, car scrap aluminium alloy wheels (SAAWs) was used as matrix material. Waste rice husk ash (RHA) was collected from a rice mill to utilize as a primary reinforcement material. Spent alumina catalyst (SAC) waste was used as a secondary reinforcement material. SAC was collected from the oil refinery industry. These wastes produced lots of soil and air pollution. However, by utilizing these wastes, some environment pollutions can be reduced. Car scrap aluminium alloy wheels (SAAWs) based composite material was developed using RHA as primary reinforcement material and SAC as a secondary reinforcement material by stir casting technique followed by squeeze pressure on the universal testing machine (UTM) in mushy zone. Microstructure behaviour shows a uniform distribution of RHA and SAC in a recycled aluminium alloy matrix. Mechanical properties such as hardness, ductility, compressive strength and tensile strength were improved using RHA and SAC as reinforcement material simultaneously in SAAWs matrix material. Thermal expansion behaviour, soil degradation test and corrosion loss were also observed to see the effect of agro-waste RHA and SAC in recycled aluminium alloy.

Synthesis and characterization of spent alumina catalyst and grinding sludge reinforced aluminium-based composite material

“…Resulting, various types of diseases occur in the human body. However, many types of pollution can be avoided if these wastes are utilized in the right place 3 . However, nowadays various types of wastes are utilized in the preparation of aluminium-based composite material.…”

“…Presence of Al 2 O 3 in the SAC attracts to the researcher for utilizing it in the fabrication of composite material. If SAC is used in the preparation of composite, the mechanical property of fabricated composite can be increased by the use of SAC and the pollution produced by SAC/GS will be reduced 3 . Table 2 illustrates the use of alumina catalyst in different applications.…”

“…However, the problem of this approach can be avoided if the density of these reinforcement particles is uniform. Keeping these proofs in mind, in this work, ball-milling of reinforcement particles has been performed to obtain the reinforcement contents in a single entity 2,3 .…”

Effect of Friction Stir Process Parameters on Mechanical Properties of Al/Eggshell/SiC Composite Material

“…On one hand, industries are an important player in the development of a nation and on the other hand they are potentially very harmful to living beings due to the wastes that are generated by them. The only way to combat from it is to find new ways for the proper treatment of such wastes and the most suitable one is recycling [3]. There are many benefits of recycling the wastes some of them are less pollution, conservation of natural resources which are replenishing very fastly and of course there would be less investment of capital [4].…”
