Title

EXPERIMENTAL STUDY ON M20, M25 & M30 GRADE CONCRETE WITH VARIABLE PERCENTAGES OF STEEL FIBERS & SILICA FUME

Abstract

Concrete is relatively brittle, and its tensile strength is typically only about one tenths of its compressive strength. Regular concrete is normally reinforced with steel reinforcing bars. For many applications, it is becoming increasingly popular to reinforce the concrete with small, randomly distributed fibers. Their main purpose is to increase the energy absorption capacity and toughness of the material, but also increase tensile and flexural strength of concrete. This study presents experimentally the combined effect of using Silica Fume and steel fibers (SF) on mechanical properties of hardened concrete. Silica Fume is used as addition by 1% to 10%, and Steel Fibers is used as volume substitution by 1%, 2%, 3%, 4% & 5%. Compressive strength, flexural strength and Workability tests are evaluated using different combinations between Silica Fume and Steel Fibers. This project involves various tests with different proportions of Silica Fume and Steel Fibers compared with three grades of concrete M20, M25 and M30. Significant improvement in the mechanical properties of concrete is observed on using Silica Fume due to its high pozzolanic activity confirming the formation of higher amount of C–S–H gel in the presence of Nano particles. Optimum content of Silica Fume is expected between 2% to 4 % which improves flexure for samples with 3% Steel Fibers, compared to samples without either Silica Fume or Steel Fibers.

Key Words

Silica Fume; Steel Fibers; Compressive Strength; Flexural Strength; Workability Test.
