Mechanical And Durability Performance Of Self Compacting Concrete Containing Fly Ash And Metakaolin, Rizwan A. Khan

Journal of Sustainable Construction Materials and Technologies

This paper is concerned with Self compacting concrete (SCC) which is a highly flow-able, non-segregating concrete that can spread into place, fill the formwork and encapsulate the reinforcement without any need for vibration. The elimination of the need for compaction leads to better quality concrete and substantial improvement of working conditions. It compacts itself due to its self-weight and is de-aerated almost completely while flowing into the formwork. Thus, the two main properties specific to fresh SCC are its filling-ability and passing ability. In this paper, different mixes of SCC were prepared and these fresh properties were investigated through V-funnel …

An Iterative Approach To Utility Contribution For Arc Flash Incident Energy Calculations, Zachary Giese

ATU Scholars Symposium

Accurately determining short-circuit fault contribution from utilities is a major challenge in arc flash incident energy analysis. Utilities may withhold or frequently alter data, and the presence of distributed generation complicates worst-case scenario identification. Additionally, commercially available software imposes limitations on scenario modeling and calculations, restricting engineers' ability to refine results. This research introduces an iterative approach that enhances worst-case arc flash identification while addressing software constraints. Initially, the study applied this approach to various facility models using commercial tools, comparing different methodologies. However, the focus has since evolved into developing an open-source arc flash calculator. This tool surpasses existing …
