Mechanical Performance and Microstructure Evolution of Nano-Titanium dioxide Enhanced Cement – A Comprehensive Experimental Analysis

Year: 2024

Type: article

Abstract: This study focuses on improving the mechanical properties and microstructure of cement-based materials, which are crucial for the durability and safety of construction projects.Conventional cement, although commonly used, has certain limitations in terms of its mechanical strength and durability.Therefore, there is a requirement for innovative methods to enhance these properties.This study investigates the potential of nano-TiO 2 (titanium dioxide) as an additive to overcome these limitations.The objective of this research is to perform a thorough experimental analysis to examine how different concentrations of nano-TiO 2 impact the mechanical performance and microstructural changes in cement paste and mortar.The study examines the influence of nano-TiO 2 on the compressive and flexural strengths of cementitious materials.It also explores how nano-TiO 2 modifies the microstructure to enhance compactness and resilience.The results suggest that incorporating nano-TiO 2 into cement leads to a substantial improvement in both compressive and flexural strengths.This enhancement is particularly notable when the nano-TiO 2 concentration is at an optimal level of 1.0% by weight.The SEM and XRD analyses demonstrate that this concentration enhances the microstructure by decreasing voids and facilitating the development of C-S-H crystals.However, excessive concentration may have negative consequences, such as the creation of extra empty spaces.The results indicate that nano-TiO 2 has considerable promise in enhancing cement-based materials, thereby aiding the advancement of construction materials that are more long-lasting and effective.This study contributes to the knowledge of how nano-TiO 2 improves cement and emphasizes its potential uses in the construction sector.
