Investigating the Strength Against Fire and Microstructure of Ultra-High-Performance Concrete

This study aims to produce Ultra-High-Performance Concrete utilizing locally available material. The experimental includes silica fume with rice husk ash in combination steel fibers. Various trials were made using different volumes of local materials and fibers UHPC. Different properties evaluated, such as compressive strength, tensile Scanning Electron Microscopy (SEM). Results show that UHPC can be produced both the examined without heating at higher temperatures providing satisfactory strength. SEM tests also performed evaluate microstructural ultrahigh-performance concrete. observations discovered transition zone between fine aggregates cement paste is improved by silica.
