Abstract

Silica-Fume, an industrial by product, has an extremely small average partical size of 0.1${\mu}{\textrm}{m}$ and when used as a concrete admixture fills the fine voids which exist in concrete. The purpose of this study is to investigate material properties of the high-strength concrete using Silica-Fume and Fly-Ash. The main variables studied are; a) water-cement ratio. b) Silica-Fume, Fly-Ash content. The maximum compressive strength of 1000Kg/$\textrm{cm}^2$ is achieved with a mix using 18% water-cement ratio, 20% Silica-Fume and 10% Fly-Ash ratio.
