Modelling compressive strength, flexural strength and chloride ion permeability of high strength concrete incorporating metakaolin and fly ash

Abstract This research paper discusses the study of the impact of cement replacement on the development of Ternary Blended Concrete by different percentages (0, 5, 10, 15, and 20) of Metakaolin and fly ash along with fibres (0 to 1) for water cement ratio 0.32. Concrete Samples were being tested for compressive and flexure strength at age of 28 days . high-strength concrete M60 has been considered and mix design is provided by Entroy and Shaklock Method. The Chloride Permeability Test was performed to recognise the durability requirements. Both mechanical and durability characteristics have been greatly improved for high-strength concrete with metakaolin and fly ash incorporation. Further models has been developed for charge, compressive strength and flexure strength considering metakaolin, fly ash and fibre replacement as independent variables. Models shows good precisions and correlations with experimental data’s.
