Synergetic Effect Of Viscosity Modifying Admixtures And Polycarboxylate Ether Superplasticizer On Key Characteristics Of Thixotropic Uhpc For Bonded Bridge Deck Overlay Rehabilitation, Le Teng, Ming Jin, Jiadi Du, Kamal H. Khayat

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Thin bonded ultra-high-performance concrete (UHPC) overlay is an advanced technology for bridge deck rehabilitation. UHPC should be tailored to secure adequate flowability and high thixotropy to facilitate mixing and placement with a low risk of sagging of the material on sloped bridge deck surfaces. The synergetic effect between nano clay (NC) and polycarboxylate ether (PCE) superplasticizer or cellulose-based viscosity modifying admixture (VMA) and PCE on the rheological properties (yield stress, plastic viscosity, and thixotropy), cement hydration, autogenous shrinkage, compressive strength, and porosity was systematically investigated. The bond strength between conventional concrete (CC) representing existing bridge deck concrete and thixotropic UHPC …

Analyzing The Effect Of The Construction Safety Audit Model Using The Business Process Model And Notation (Bpmn) Method On Improving Communication And Collaboration Between Stakeholders., Muhammad Ghazali, Danang Budi Nugroho, Yusuf Latief

CSID Journal of Infrastructure Development

The significant increase in infrastructure development is directly proportional to the rising accident rate in the construction sector, making it one of the highest-risk sectors for accidents. This phenomenon indicates that existing construction safety audits have not been effective in preventing accidents, largely because audits are generally conducted only at the construction stage. Audits at the design stage, however, have the potential to impact accident prevention significantly. Therefore, this research aims to develop a construction safety audit model using the Business Process Model and Notation (BPMN) and analyzes the impacts on stakeholder communication and collaboration. BPMN was chosen because it …

Other Angles: Queer-Ing Approaches To Museum Design, Gregory Mathieu

Masters Theses

This research explores how the epistemology of queer theory can be extrapolated as an instrument for mediating positively in museum environments. As a tool, queer theory deconstructs taxonomic societal understandings around identity, self, and other to expose the imbalance of power present in the world. It impugns the various mechanisms that are involved in the making, perpetuation, and dissemination of social norms and ideals.

The word queer academically and colloquially has many definitions, interpretations, and usages, but this thesis is most concerned with its application as a verb. Used as such, to queer can be defined as the process of …
