Properties of Ultra-High-Strength Concrete Using Silica Fume-Premixed Cement

Abstract

 Silica fume-premix cement (SFPC^Ⓡ), which enables to manufacture ultra-high-strength concrete (UHSC) with design strength of 100N/mm² over, has been newly developed July 2006. This report shows the experimental results regarding fresh properties, strength properties, and durability of SFPC^Ⓡ-used concrete with water-to-binder-ratio of 0.13-0.27. This report also demonstrates fluidity of fresh concrete and strength of concrete in structure of SFPC^Ⓡ-UHSC, produced at ready-mixed concrete plant practically.
