Review on Performance Evaluation of High-Performance Concrete Using Ultrafine Mineral Admixture.

Abstract

This study aims to investigate the effects of incorporating ultrafine mineral admixtures on the properties of High-Performance Concrete (HPC). The research examines the performance enhancements achieved through the addition of these admixtures, focusing on aspects such as compressive strength, durability, workability, and microstructural characteristics. Experimental procedures involve varying concentrations of ultrafine mineral admixture in concrete mixes and conducting a series of tests to evaluate the resultant properties. The findings of this study will contribute to the understanding of utilizing ultrafine mineral admixtures to enhance the performance of high-performance concrete, offering insights for optimizing concrete mix designs in construction applications. High-Performance Concrete (HPC) has garnered significant attention in recent years due to its superior mechanical properties and durability characteristics, making it suitable for a wide range of structural applications. The research explores the effects of incorporating various concentrations of ultrafine mineral admixture, such as silica fume or metakaolin, on the compressive strength, modulus of elasticity, shrinkage, permeability, and microstructural properties of HPC.Experimental investigations involve the preparation of HPC mixes with different proportions of ultrafine mineral admixture, ranging from 2% to 10% replacement of cement by weight. Standard testing protocols, including compressive strength tests, modulus of elasticity measurements, shrinkage evaluations, permeability assessments and Scanning Electron Microscopy (SEM) analysis, are conducted to assess the performance of the concrete mixes. Results indicate that the inclusion of ultrafine mineral admixtures leads to improvements in compressive strength, modulus of elasticity, and durability properties of HPC.
