| Abstract | ||
| This article addresses the urgent need for sustainable advancements in concrete materials within the cement industry, a sector that consumes vast amounts of nonrenewable resources and contributes approximately 5% of global CO2 emissions. The study investigates the effectiveness of nano cellulose, nano silica, and nano clay as partial replacements to enhance concrete properties. By examining the influence of varying nanoparticle percentages on compressive strength, flexural strength, water absorption, impact resistance, and abrasion resistance, this research provides valuable insights into their performance. The study identifies an optimal weight ratio of 0.75% nano cellulose for achieving maximum compressive strength, alongside a combination of 1.25% nano silica and 0.75% nano cellulose for superior flexural strength. However, it is noted that excessive concentrations of nano cellulose may result in agglomeration and uneven dispersion of nanoparticles, adversely affecting concrete performance. The article underscores the challenges associated with incorporating larger quantities of nanoparticles and emphasizes the necessity for further research to improve dispersion techniques, ultimately enhancing concrete strength and durability. Additionally, a brief overview of the study's experimental methods is included to provide clarity on the research approach. In conclusion, this study highlights the promising potential of nano cellulose, nano silica, and nano clay as additives for enhancing concrete performance. By optimizing dosages and addressing dispersion challenges, these nanoparticles offer a viable path toward sustainable concrete production with improved mechanical properties and enhanced durability. | ||
