Abstract
The application of nanotechnology in the concrete adds new efforts to improve its performance. Due to the very small size of nano materials, the properties of concrete can be influenced by changing its microstructure. The study involved the use of Silica fume (3%,6%,9%) and nano-silica (1%,2%,3%). As the percentage of Silica fume and nano silica increases, there is an increase in strength. The widespread use of concrete in structures, from buildings to factories, bridges and airports makes it one of the most searched materials. Due to rapid population explosion and the rise of technology to meet these needs, there is an urgent need to improve the strength and durability of the concrete. Among the various materials used in concrete production, cement plays an important role in the construction sector due to its size and adhesive properties. Consequently, to produce improved concrete, the cement humidification mechanism should be studied properly, and better alternatives should be proposed. In this study, the cement is replaced by silica fume and nano silica materials. We also determined the number of predictions of cubes in the program. This work explores the standard optimization ratio for silica fume and nano-silica to get the best compressive strength. Further to meet the Indian standards, all the concrete mixtures were tested. These tests include performing Slump and the Compressive strength test. 24 cubes were moulded for the compressive strength, and the curing ages of 7 and 28 days were applied in this work. The result proved an increase in compressive strength, durability, and various other properties of concrete by adding nano silica and silica fume in concrete.
