Stress Strain Behaviour And Modulus Of Elasticity Of Steel DustCollector Concrete

Abstract

Steel dust collector concrete is concrete with added material processing steel dust waste. In the reinforced concrete structures design, for modeling the behavior of concrete materials in the burden needs to know the form of stress strain curves and modulus of elasticity. This research aims to investigate the stress strain behavior and modulus of elasticity of steel dust collector concrete. Test speciment is used a concrete cylinder with 15 cm diameter and 30 cm height. The mixture of concrete was water cement ratio (w/c) varried: 0.68, 0.57 and 0.51 as well as the amount of waste 0% and 10%. Stress strain behavior and modulus of elasticity of concrete was tested at 28 days. The results of this study indicates that compressive strength and modulus of elasticity of concrete has increased with the addition of waste steel dust collector. Modulus of elasticity of steel dust collector concrete is higher than the formulation of SNI-03-2847-2000. Form of stress strain diagram of steel dust collector concrete is steeper than the concrete without waste. The maximum strain of concrete with no waste is higher than concrete waste. Strain at peak load of the steel dust collector concrete with w/c 0,51 has increased. Based on the stress strain diagram form and collapse model, steel dust collector concrete is more brittle than concrete without waste.
