Stress-Strain Relationship of High-Performance Concrete in Compression

Alan S. Habib, Omar Q. Aziz

Abstract

The application of High-Performance Concrete (HPC) technology has grown considerably in the construction industry due to the advantages associated with its mechanical properties and durability of concrete. The stress-strain model of concrete is essential in the design stage of structural members. Since the development of HPC, the behaviors of many stress-strain models for HPC have been predicted to be different from each other due to the different mix proportions and material properties. This unique study utilizes a comparison exclusively between three different strengths of HPC at different ages to produce the stress-strain curve. Many stress-strain curves are available, but no research has been conducted on comparing three different stress-strain curves of HPC in compression, so this study aims to do that. In this study, an experimental technique (compressometer) is used to generate the stress-strain curves of HPC in compression with the compressive strengths of approximately 40, 60, and 80 MPa mixes 1, 2, and 3, respectively. The compressive strength variation was obtained by varying the water to binder ratio of the mix, addition of silica fume, superplasticizer (PC200), and the age of testing. It was observed that at the maximum strain of 2x10-3, the compressive strength of mix2 is increased by 21.4% compared to mix1, mix3 has increased by 9.8% compared to mix2, and finally, mix3 has increased by 29.1% compared to mix1. The consequence of these variables on the shape of stress-strain curves is presented and discussed.

 

Keywords: compression, high performance concrete, silica fume, strain, stress.
