A basalt stone-crushing plant's byproduct is basalt powder. Proposing the use of these byproducts presents significant disposal, environmental pollution and health risk issues. Basalt can be employed as a novel mineral additive and had obvious potential for pozzolan activity. This study evaluated basalt powder's (BP) usage as a partial replacement (5, 10, 20%) of ordinary Portland cement (OPC) to enhance cement pastes properties. The conducted investigations were to ascertain physicomechanical properties and corrosion resistance using electrochemical impedance spectroscopy (EIS) of cement pastes with a partial addition of basalt powder in different solutions of 5% NaCl and 5% MgCl2 for up to 270 days. Infra-red spectroscopy (IR), X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) and Energy-dispersive X-ray spectroscopy (EDX) were also performed to investigate the hydration process and microstructure formation of the basalt blended paste. Results showed that replacing OPC with basalt powder improved the compressive strength of cement pastes. This is a result of the addition of basalt powder filler. The results of the BP20% specimen in 5% NaCl showed the highest values of Rp 953 ohms.cm2 after 270 days. This indicates high corrosion resistance as a result of binding by high Al2O3, which reduced free chloride in the solution. Furthermore, the decrease in iron rebar bonds in 5% MgCl2 compared to 5% NaCl showed a highly adherent protective layer developed on the surface of the rebar.

“…[8][9][10] Liquid cooling is widely used due to its strong heat transfer capability and flexible arrangement of cooling pipes. [11] Liquid cooling generally involves injecting coolant into heat dissipation structures of various shapes, using the flow of the coolant to carry away the heat generated by the battery pack. Yang et al [12] compared the temperature responses of cylindrical lithium-ion batteries under rapid charging conditions with liquid immersion cooling versus natural convection.…”

To investigate the microchannel liquid cooling system of 18650 cylindrical lithium battery packs, cooling systems with varying numbers of microchannels are developed and they are analyzed through numerical simulations using COMSOL software. The findings reveal that lower coolant inlet temperatures correspond to lower maximum temperatures during discharge, with temperatures decreasing closer to the inlet. When the coolant passes through a 3.6 mm diameter or at an inlet flow rate of 0.1 m s−1, an increase in Reynolds number results in a decrease in the highest temperature of the cells. However, this temperature reduction slows down when Re exceeds 400. The annular channel cooling structure demonstrates superior cooling effects and temperature uniformity. Optimization opportunities exist to reduce the number of inlets. The dual‐inlet and dual‐outlet cooling structure has been enhanced by adjusting the number of channels in the annular channel design. This modification has resulted in a maximum temperature reduction of 4.62 K and a temperature difference of less than 5 K compared to the initial reference group, demonstrating effective cooling performance.
