Characteristics of steel reinforcement are as important as that of concrete mixes towards the stability and structural integrity of a project. Present reinforcing steel bars manufactured in Saudi Arabia exhibit a variety of different material properties. The aim of this research is to evaluate and make a statistical analysis on the mechanical and chemical characteristics of steel bars. This data will help identify the quality of steel being produced in accordance with ASTM A615 standard and identify rebars from manufacturers or suppliers which fail to meet the standard. Additionally, a quantitative understanding of the variability of steel properties produced in different industrial zones will assist in the development of strategic planning for each region and Saudi Arabia. Similar research on steel rebars is currently being conducted every five years in countries such as USA and the UK but is a first for Saudi Arabia. This research uses a tensile testing machine to obtain the mechanical properties and a mobile arc spark spectrometer to obtain the chemical properties of the specimen. A thorough investigation of 152 samples is contained within this research from 7 manufacturers along with the results and analysis.
For this research – a very large dataset sample is required to be taken from all rebar manufacturers in KSA. From the results a quantitative understanding of the variability of steel properties produced in different industrial zones will assist in the development of proper quality assurance strategic planning for each region and Saudi Arabia. The uncertainties in raw material input and fabrication approach which will differ substantially from one manufacturer to another can then be categorized statistically in the quality of rebars produced. The statistical analysis of the data can then be used to indicate any short comings regarding the process or the raw material choice for each industrial zone.
