Abstract

The retrofitting and rehabilitation of deteriorating structures pose significant challenges, requiring innovative materials and techniques to ensure longevity and enhanced performance. This dissertation explores the utilization of silica fumes and metakaolin in polymer-modified concrete mortar as a sustainable approach to address these challenges. The primary aim is to investigate the synergistic effects of these supplementary cementitious materials (SCMs) on the mechanical properties, durability, and microstructural characteristics of the modified mortar. The objectives of this study encompass evaluating the performance enhancement achieved through the incorporation of silica fumes and metakaolin, optimizing mix proportions to achieve desired properties, assessing microstructural changes, and conducting field performance evaluations to validate the effectiveness in real-world applications. Comparative studies with conventional methods provide insights into the economic and environmental benefits of the proposed approach. Through laboratory experiments and field trials, this research demonstrates that silica fumes and metakaolin can significantly improve the compressive strength, flexural strength, bond strength, and durability of polymer-modified mortar. Microstructural analyses reveal reduced porosity and enhanced hydration products, contributing to enhanced performance and long-term durability. The findings underscore the potential of SCMs in polymer-modified concrete mortar as a sustainable solution for retrofitting and rehabilitating structures, offering both technical advancements and environmental benefits.
