Properties of Self Compacting Concrete Containing Silica Fume as a Sustainable Alternative: A Review

Abstract

The most frequently used building material on this planet is concrete. Concrete is the supreme user of natural resources as a result of its widespread use as construction material. Cement production produces significant amount of greenhouse emissions. The protection of environment has become challenging in many developing countries, 7-8% of CO2 is produced by the cement industry that causes huge damage to the environment. In concrete production, Silica fumes can be a partial alternative to cement. In this study, the properties of self-compacting concrete incorporating silica fumes are reviewed. Slump flow, funnel, L-box, compressive strength, split tensile strength and flexural strength are among qualities of self-compacting concrete with silica fumes that have been discussed in this study. The cement was replaced by silica fumes in the ratio of 0% to 30% in concrete, cement content can be reduced, which turns into an eco-friendly solution.
