Abstract

The intricate relationship between blast furnace slag, metakaolin, and concrete's Strength in compression is examined in this thesis. This work aims to provide a thorough knowledge of their combined impact as extra chemicals that resemble cement (SCMs) in mixers for concrete designs. The capacity of supplemental cementations materials (SCMs) to enhance concrete performance and reduce the environmental consequences associated with cement manufacture is gaining more and more recognition.Both metakaolin and blast furnace slag, which are recognized for their pozzolanic qualities, enhance the qualities of concrete when added to mixtures. The iron production sector produces trash called blast furnace slag, while calcined kaolin clay is used to make metakaolin. However, further research is necessary to determine the extent of their influence on concrete's Strength in compression as well as the underlying mechanisms that account for these effects. This research employs a systematic approach to assess the compressive capacity of concrete samples using laboratory testing. These samples are created by substituting a portion of the cement used in Portland with various ratios of blast furnace slag and metakaolin. Additionally, the study looks at the microscopic characteristics, rate of fluid absorption, and capacity of blast furnace slag and metakaolin to react with calcium hydroxide in order to comprehend how these factors impact the features of concrete.By examining the results and contrasting them with control samples, the thesis seeks to illuminate the relationship between these supplemental cement-based substances (SCMs) and the matrix that contains cement. It highlights how these SCMs help to make concrete stronger and more resilient. Furthermore, a number of factors, including the range of particle sizes, chemical makeup, and interactions between cementitious binders and other ingredients, are closely scrutinised in order to pinpoint the primary mechanisms responsible for differences in concrete performance. The study's conclusions have a significant impact on how Mix Grade are made and provide essential information to experts, researchers, and engineers working on sustainable construction techniques. Understanding how blast furnace slag and metakaolin impact the characteristics of concrete allows one to make well-informed judgments when choosing and altering the amounts of components. This promotes the building of more robust and ecologically friendly concrete buildings.Furthermore, by advancing our understanding of concrete technology, this work facilitates the widespread use of supplementary cementations materials (SCMs) in building industry procedures. This thesis looks closely at how blast furnace slag and metakaolin affect concrete's Strength in compression in an effort to support the construction of robust and sustainable infrastructure.
