摘要

Agricultural byproduct Sugarcane bagasse ash (SCBA) and industrial byproduct eggshells are two examples of these pollutants that contaminate soil. The use of these wastes, however, has the ability to reduce the impact of some environmental problems. An aluminum-based composite material was made in this research using SCBA and eggshells as reinforcing elements. A homogenous combination was achieved by subjecting carbonized eggshell ash (CESA) particles and SCBA to a 72-h ball milling process. A range of 3–12% CESA to bagasse ash (BA) particle ratios were used in the composite. The matrix material, which was made of aluminum, showed homogeneous dispersion of the ball-milled reinforcing particles. The study demonstrated that incorporating 6% carbonized eggshell ash (CESA) and 6% sugarcane bagasse ash (SCBA) into aluminum significantly improved its mechanical properties i.e., tensile strength and hardness. The results showed that tensile strength of aluminum composite with 6% CESA and 6% SCBA was 186.65 MPa, after heat treatment, while the hardness was 56 Brinell Hardness Number (kgf/mm2). As a result of heat treatment, the hardness increased by 50% and the tensile strength by 28.59%. In order to evaluate the effects of carbonized eggshell and SCBA incorporation into aluminum alloy, thermal expansion behavior and corrosion loss were also observed. After heat treatment, the AA3105 composite containing 6% eggshell powder and 6% BA showed a corrosion loss of 0.012 gm and a thermal expansion of 4.35 mm3, respectively.
