Abstract
The construction industry is one of the most important users of nanostructured materials due to its requirements in terms of strength, durability and high performance. The nanosilica and nanomaterials are discussed and the results of the new state experiments of slump current, T50, hopper time V, and box L are investigated. According to the results for all the designs made in this project, the slump flow is reduced compared to the control sample. With nanomaterials, this slump reduction is much more visible. Also, due to the slump decrease in T50 time by adding nanomaterials, we observed that by adding nanomaterials, this increase is longer than the designs containing nano-silica and in this study the funneling time is increased by adding nanomaterials, which increases in the samples containing Nano-copper is much clearer.
