The Impact of Silica Fume & Steel Fiber on Elasticity Modulus

Abstract

The results of a study on the effect of FRC hybridization and Silica Fume on the Modulus of Elasticity are presented in this paper. For a wide range of construction and engineering applications, concrete's elastic modulus is a critical feature that enables reliable predictions of its fundamental behaviour. Elastic modulus concretes made with steel fibre and silica fume are tested and analysed in this study. There were three different combinations of 50 and 67 Aspect Ratio steel fibres, 0.5, 1.0, and 1.5 percent Fiber volume each, with 3 percent, 6 percent and 9 percent Silica Fume substituted for cement in each. An unfibered concrete mix gets a boost from the addition of silica to it. For the sake of comparison, a steel-based Fiber was cast as well. Tests were performed on the elastic modulus of hardened concrete reinforced with steel fibres and Silica Fume, and the results were compared to those of controls after 28 and 90 days of curing, respectively. According to the findings, adding silica fume to the tested concretes increased their modulus of elasticity significantly. Additionally, the addition of steel fibre raised the elasticity modulus slightly.
