Experimental Investigation on the Workability and Mechanical Properties of Metakaolin Concrete

This paper abstract provide the development of high-performance and sustainable concrete has led to the increased use of supplementary cementitious materials(SCMs) such as metakaolin. Metakaolin, a calcined clay, demonstrates excellent pozzolanic reactivity and contributes to enhanced mechanical and durability properties of concrete. This abstract explores the impact of metakaolin as a partial replacement for cement, focusing on mechanical performance, workability, and durability.Utilizing particle packing models and a range of replacement percentages. The metakaolin improves compressive, tensile, and flexura strengths while enhancing resistance to chemical attack and reducing porosity.Optimal improvements were observed at a replacement level of 10-15%. Advancement in construction technology have sparked transformative changes in infrastructure development. Due to the innovative construction around the world and it's impact on environment. The requirement to built more sustainable and low maintenance infrastructure has become very important.
