Studies On Behaviour Of Concrete Using Micro And Nano Materials In Compression Flexure Shear And Torsion

Abstract

Concrete ranks second in human consumption after water. Every building uses it. Cement manufacture uses a lot of energy and emits a lot of CO₂. As a consequence, many researchers have studied several material combinations to limit carbon dioxide emissions and energy dissipation, which pollute the environment and destroy the ecosystem. Microsilica, GGBS (slag), and nanosilica were employed as mineral admixtures to partly replace cement by weight in this investigation. This research examined concrete behaviour with varying particle sizes and percentage replacements. Steel and iron industry waste like microsilica and GGBS harms the environment. Microsilica and GGBS promote concrete reinforcement via pozzolanic reactions due to their cementitious characteristics. These reactions reinforce concrete with lime and silica. When cement is mixed with water, C-S-H gel and Ca(OH)₂ develop, which reinforces concrete when combined with silica. This process reduces concrete's calcium concentration. Experimental mechanical property investigation comprises compressive, flexural, shear, and torsional strength. The above experiments identify micro silica, GGBS, and nanosilica particle sizes for various percentage replacements. Tables and graphs show system behaviour with varying percentage replacements.
