Use Of Hybrid Fibers And Shrinkage Mitigating Materials In Scc For Repair Applications, Kamran Aghaee, Kamal H. Khayat

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Self-consolidating concrete (SCC) is used to repair structural elements with congested reinforcement or restricted access to placement and consolidation. In addition to adequate flowability, passing ability, filling capacity, and stability, adequate bonding to the substrate and reinforcing bars, low shrinkage and cracking resistance are required for successful repair. This study employs various shrinkage mitigating materials, including expansive agent (EA), coupled use of EA with shrinkage reducing admixture (SRA), and EA with pre-saturated lightweight sand (LWS) to fulfill these requirements. The effect of these materials on the performance of SCC made with a hybrid synthetic (PP) fiber and a hybrid steel-synthetic …

Design Of A Test For Research On Architectural Features Of Streetscape, Maria E. M. Carlier, Cristian A. Maestre, Gladys E. Maestre

Research Symposium

Background: The architectural experience may impact people’s behavior, health, and well-being, engaging several neural networks. Sensory-motor networks mediate motor responses such as approach and avoidance and spatial navigation in response to stimuli. Limbic networks process feelings and emotions. Memory-related networks support personal experiences, education, and culture. The interaction between architecture and brain sciences is known as neuroarchitecture which promises to offer biologically inspired insights into the design of spaces. We are interested in the study of neuroarchitecture applied to the streetscapes of neighborhoods in South Texas. The primary purpose of this study is to design a cognitive test to assess …

Collection And Analysis Of Architectural Features In Streetscapes In South Texas, Cristian Maestre, Maria E. M. Carlier, Gladys E. Maestre

Research Symposium

Background: The built environment of neighborhoods influences the health and well-being of residents. One approach to studying the impact of such a built environment on people's health is through the study of the memorability of the architectural features (AFs) in streetscapes. In this direction, we raise the question: what AFs are more memorable? Understanding how AFs impact cognition will allow us to propose neighborhood designs that consider this finding to foster people's health and well-being. However, AFs in streetscapes are not universal they need to be studied in specific historical, cultural, and geographical contexts. In order to analyze the memorability …

Reframing Perceptions Of Signares In French Colonial Senegal, Gabriela E. Weaver

Swarthmore Undergraduate History Journal

Fifteenth to nineteenth-century French Colonial Senegal was a period of unprecedented cultural contact and convergence in Western Africa. With these interactions came new social hierarchies and the emergence of the signare identity. Signares were wealthy mixed-race and African Women who became involved with French men. This paper examines nineteenth-century art by Frenchman David Boilat and Stanislas Darondeau, and the eighteenth-century house of signare Anne Pepin. It critiques the racism and sexism depicted within Boilat and Darondeau’s work as well as its misinterpretations by contemporary scholars Mark Hinchman and George E. Brooks. Signares were knowledgeable entrepreneurs rather than manipulative and seductive …

An Investigation Of The Physical And Thermal Properties Of Irish Hemp Fibres As A Loose-Fill Insulation Product, Killian Markey, Sameer Mehra Dr., David Palmer, David Knight, Timothy O'Leary

Conference papers

Construction and built environment sectors account for approximately 37% of Ireland’s carbon emissions. Of this 37%, 14% of the emissions consist of embodied carbon emissions from the construction materials from the production to the end-of-disposal of buildings. The construction industry can reduce its embodied carbon by using materials with a lower embodied carbon. Hemp fibre batt insulation is an example of a bio-based material and a lower embodied carbon alternative to conventional insulations. The existing hemp fibre batt insulation is typically composed of hemp fibres with a polyester binder. These polyester binders have higher embodied carbon while also being a …
