Mechanical And Durability Performance Of M60 High-Performance Concrete Incorporating Fly Ash, GGBS, Metakaolin And Nano Silica As Cement Replacements

Abstract

This study examines at how Fly Ash (FA), Ground Granulated Blast Furnace Slag (GGBS),Metakaolin (MK) and Nano Silica (NS) all work together to improve the performance of High-Performance Concrete (HPC) with a target compressive strength of 60 MPa. We employed a superplasticizer based on polycarboxylate ether (PCE) to make sure the workability was good and the water-to-binder ratio was low. The way these pozzolanic binders work together makes more calcium silicate hydrate (C–S–H) gel, improves the microstructure, and makes it very strong against acid, sulphate and chloride assaults. This HPC system is best for infrastructure that is exposed to conditions that are chemically hostile.
