Özet
This study investigates the effect of silicon carbide (SiC) powder on cement pastes. SiC was added in various percentages by weight of cement (1%, 2%, 4%, 8%, 12%, and 16%). The spread diameter, mechanical strength, chloride permeability, capillary water absorption, and electrical conductivity of each mixture were determined, and microstructural analyses (SEM and EDX) were conducted. The results indicate that SiC decreases the spread diameter of the mortar while increasing its mechanical strength and electrical conductivity. Specifically, 2% and 4% SiC additions resulted in the highest strength improvements. Chloride permeability tests showed that the resistance of concrete to chloride ions improved over time, with permeability levels significantly decreasing. Microstructural analyses revealed that SiC influences the formation of C-S–H and C-H structures in the cement matrix, enhancing mechanical strength and overall durability. This study highlights the potential of SiC to improve the mechanical properties and electrical conductivity of cement in the industry, suggesting avenues for future research to explore different SiC concentrations and application methods in greater detail. © The Author(s), under exclusive licence to Springer Nature B.V. 2024.
