INFLUENCE OF NANO-CLAY ON THE PROPERTIES OF ALKALI-ACTIVATED WATER-COOLED SLAG GEOPOLYMER

Аннотация

This study investigates the influence of nano-clay on the properties of alkali-activated water-cooled slag geopolymer, aiming to enhance its mechanical performance and durability. Alkali-activated materials have garnered significant attention as sustainable alternatives to conventional cement due to their lower carbon footprint and superior resistance to environmental degradation. In this research, varying proportions of nano-clay were incorporated into the geopolymer matrix, and a series of experiments were conducted to assess the resulting mechanical properties, including compressive strength, flexural strength, and workability. Additionally, the microstructural characteristics were analyzed using techniques such as scanning electron microscopy (SEM) and X-ray diffraction (XRD) to elucidate the effects of nano-clay on the geopolymer formation process and bonding mechanisms. The results indicate a marked improvement in mechanical properties with optimal nano-clay incorporation, alongside enhanced durability against chemical attacks and freeze-thaw cycles. This study contributes to the growing body of knowledge on the use of nano-materials in geopolymer technology, highlighting the potential for developing high-performance, eco-friendly construction materials.
