| Popis: | This The investigation of this present research was to examine the performance of concrete by substituting the use of natural aggregates with either the coarser aggregates or finely formed aggregates, of high-performance concretes and variations in the properties of concrete composed of Nano Silica (NS), Silica Fume (SF) and Steel Slag (SS). Steel slag and silica fume are a waste product that can be cost-effective when utilized in concrete use. Therefore, this analysis aims to understand how the possibility of using the steel slag, nano-silica, and silica fume produced in India as a substitute for natural aggregate, cement, and finer aggregates in cement concrete. Test and analysis results explain the combined effects of nano-silica, silica fumes, and steel slag on the strength of concrete. Six samples were prepared with different percentages of these selected admixtures – nano-silica, silica fume, and steel slag. The outcomes indicate the incorporation of these admixtures in a controlled manner ie. Fixing their content percentages increased the strength minorly up to a certain limit after which it follows a downward trend beyond this limit. |
