Abstract

The exploration of the dielectric properties of pozzolan-modified eco-efficient cement pastes has become an important field of research in the quest for innovative construction materials. This study investigates the intricate relationship between dielectric constant (ε’) and loss tangent (tanδ) in various cement paste compositions, providing significant insights into their electronic characteristics. Through a comprehensive analysis, we examine the effects of both the type and dosage of pozzolan on these properties, shedding light on how these parameters affect the overall performance of the materials. The results of our analysis reveal intriguing patterns. Particularly noteworthy is the scenario where 30 wt% of cement is replaced with diatomite, resulting in a significant decrease in the loss tangent from 1.06676×10-9 to 4.76856×10-11. This finding underscores the potential of diatomite as a viable`modification to enhance the energy dissipation properties of cementitious materials. These observations have significant implications for developing durable and resilient structures and the sustainable integration of industrial waste into construction materials. This study emphasizes the importance of understanding the dielectric behavior exhibited by cement paste blends. By examining the correlation between different types of pozzolan, their respective dosages, and the resulting variations in dielectric characteristics, this research makes a valuable contribution to the extensive field of materials science and engineering.
