“…The impacts determined in the S/N ratio study may be classified into three categories: the higher the better, the lower the better, and the nominal the best. The higher the thermal conductivity, the better was selected (equation ( 3)), suggesting that the higher the thermal conductivity, the more desirable (Dan-Asabe et al 2019, Samuel et al 2022, Ibrahim et al 2023a.…”

Aluminium metal matrix composites have been gaining traction in recent years due to their good mechanical properties and low weight. Particulate reinforcements for the improvement of its properties have been explored. This research aimed to determine the optimal composition of the reinforcement content (pumice powder and carbonated coal particles) and processing parameters (stirring speed, processing temperature, and stirring time) on the thermal conductivity of the developed material and also to characterize the constituents using XRF, XRD, and SEM/EDX. The Taguchi optimization approach and regression analysis were used for the optimization and statistical analysis, respectively. The results revealed the optimum setting for stir casting process factors as regards thermal conductivity to be 2.5 %, 5.0%, 300 rpm, 850 °C, and 5 min for pumice powder, carbonated coal particles, stirring speed, temperature, and time, respectively. The obtained optimal thermal conductivity was 120.40 W/m°C which is a 131.54 % improvement of the conventional grey cast iron brake disc. The particulate reinforcements (pumice powder and carbonated coal particles) and the processing factors all had significant effects on the thermal conductivity of the material, with the carbonated coal particles having the highest percentage contribution of 16.51%, as established by the analysis of variance. A model for predicting the thermal conductivity was developed using regression analysis, and high prediction accuracy was established with R-Square, R-Square (adj), and R-Square (pred) values of 94.68 %, 88.60 %, and 79.94 %, respectively. The results of the characterization show the presence of hard compounds such as silica, iron oxide, and alumina in pumice powder and carbonated coal particles.

High performance concrete is obtained by the inclusion of mineral admixtures like silica fume and fly ash in the concrete.. The research explores the viability and performance of sustainable concrete by introducing zeolite powder as a partial substitute for cement and steel slag as a partial replacement for coarse aggregate in M-70 grade concrete. Zeolite powder, possessing pozzolanic properties, is a natural or synthetic aluminosilicate material, while steel slag is an industrial byproduct with potential as an alternative aggregate source. The main objective is to investigate the impact of zeolite powder and steel slag on the development of High-Performance Concrete (M-70) in accordance with BIS standards.The formulation of high-performance concrete involved replacing 12.5%, 15%, and 17.5% of the cement with zeolite powder and varying the proportion of steel slag as a replacement for coarse aggregate (ranging from 30% to 55%). A comprehensive mechanical test was conducted on these specimens and compared with conventional concrete. Among the 21 mixes, the optimal combination was identified, incorporating 15% zeolite powder as a cement replacement and 45% steel slag as a coarse aggregate replacement, resulting in superior performance compared to conventional concrete.Subsequently, the experimental results were compared with predicted outcomes using the Taguchi method. The close alignment between the values obtained experimentally and those predicted further validates the effectiveness of the optimized mix ZP15SS45. This mix was further studied for water absorption, non-destructive testing, and microstructural analysis. The results from these investigations indicate that the optimum mix outperforms conventional concrete in terms of water absorption, non-destructive testing, and microstructural characteristics.

“…The weight loss and corrosion rate of the specimens were evaluated using the ASTM G31-12 standard laboratory immersion corrosion test technique. The specimens were immersed in a simulated seawater solution prepared with 3.5 g of NaCl per 100 mL of distilled water for a duration ranging from seven (7) to twenty-one ( 21) days. The corrosion rate was determined in mils per year (mpy) using equation 2 [22,23]:…”

“…From the findings of Dwiwedi et al [7] and Ibrahim et al [8], one essential factor that limits the application of aluminum metal matrix composites is their high cost of production due to the use of expensive synthetic reinforcements such as SiO 2 , Al 2 O 3 , SiC, etc. To overcome this obstacle, researchers have shifted their focus to utilizing low-cost and lowdensity reinforcements such as eggshells, pumice, bagasse, carbonated coal, and others [1,3,7]. Among these alternatives, eggshells have gained considerable recognition due to their affordability and abundance.…”

In this study, different sizes (25, 50, and 75 µm) and volume fractions (1, 2, and 3 wt%) of calcined eggshell particles were utilized to strengthen the Al-Si-Mg alloy. Several experimental runs were conducted to assess the impact of particle size and concentration on both physical properties (density, corrosion, and thermal conductivity) and mechanical properties (hardness, yield strength, impact energy, and modulus of elasticity). The findings revealed significant enhancements in hardness (21 %), yield strength (61 %), modulus of elasticity (43 %), and thermal conductivity (34 %). Conversely, a reduction of 62 % in impact strength and 8 % in density was observed. The corrosion rate displayed an increase from 0 to 16.67 mpy. Analysis using XRD and XRF techniques identified CaO and Al2O3 as the primary constituents of the eggshell. Optical micrographs consistently showed cored (segregated) dendritic structures typical of castings cooled under normal conditions in the Al-Si-Mg composite. SEM micrographs, EDS spectra, and area analyses confirmed a uniform distribution of Calcined Eggshell Particles (CEP) within the composite films. Additionally, an optimal calcination condition for the eggshell particles was determined to be 900 °C for 2.5 h, resulting in a CaO yield of 99.62 %.
