English Abstract

The main objective of this paper is to determine the effect of silica fume on the workability, compressive strength, and permeability of concrete.

Many experiments were carried out by replacing cement with different percentages of silica fume.

The silica fume was replaced by 0%, 5%, 10%, 15% and 20% for water-cement ratios 0.38.

For all mixes, compressive, permeability, and workability were determined at 3,7,14, and 28 days.

The results showed that the compressive strength of 51.24 MPa, 53.01MPa, 54.38MPa, 57.77 MPa, and, 63 MPa respectively.

The optimum of specimen’s replacement percentage is 15% silica fume had the highest strength 63MPa.

Results of the permeability showed that specimens containing silica fume have low permeability and it also showed that specimens containing 15%, 20% optimum specimens.
