ABSTRACT
This paper presents the use of ultra-fine materials in High Strength Concrete (HSC) as a novel approach to enhance its mechanical and durability properties. This report focuses on he utilization of Ultra-fine Ground Granulated Blast Furnace Slag (UFGGBS) as an SCM in concrete while GGBS have been widely used as a partial replacement for cement ,limited research has been conducted on the effect of ultra-fine GGBS. This experimental investigation explores the incorporation of ultra-fine materials, specifically nanoparticles, into HSC Mixtures to achieve superior performance characteristics. The study focuses on assessing the impact of various types and dosages of ultra-fine materials on the compressive strength, Flexural strength and durability properties of HSC. In this research , ultra-fine materials including river sand , GGBFS,stone dust and super plasticizes are incorporated into HSC Mixture at different proportions. Ultra - fine GGBS can enhance the strength and durability of concrete while reducing its carbon foot print. Concrete mixes of M60 Grade were formulated with varying percentages ( 5%, 10% , 20%,25%, 30%) of ultra-fine GGBS replacing cement. The finding of this study provide valuable insight into the effectiveness of incorporating ultra-fine materials in HSC mixtures. The findings show that incorporating ultra-fine materials considerably enhances the mechanical strength and durability of high-strength concrete (HSC). Additionally, the research determines the most effective amounts and combinations of these materials to optimize performance, providing useful insights for their practical use in HSC manufacturing. Overall this research contributes to advancing the understanding of utilizing ultra-fine materials in HSC mixtures, paving the way for the development of high performance and sustainable concrete materials for various construction applications.
