Hydration Of High-Alumina Calcium Aluminate Cements With Carbonate And Sulfate Additives, Jonathan Lapeyre, Sai Akshay Ponduru, Monday Uchenna Okoronkwo, Hongyan Ma, Aditya Kumar

Chemical and Biochemical Engineering Faculty Research & Creative Works

This study investigated the influence of limestone (LS) and calcium sulfate (C$) mineral additives on the hydration kinetics of high-α-Al₂O₃ calcium aluminate cement (CAC) utilizing experimental techniques and thermodynamic simulations. Increasing the replacement level of limestone or calcium sulfate increased the cumulative heat of the hydration reaction. The limestone exhibited limited acceleratory effects to the CAC hydration kinetics due to the coarseness of the powder. The coarse particle size distribution limited any heterogenous nucleation that would have occurred with a finer particle size as well as the intrinsic insolubility kinetically limits the formation of monocarboaluminate phases. Conversely, …

Design For A Spectrum, Brooke Warden

Interior Design Undergraduate Honors Theses

Autism Spectrum Disorder (ASD) is a growing disorder across the world. ASD affects around 1 in every 68 children in the United States (Block, 2018). This disorder results in significant social, intellectual, and behavioral changes within a child, and create challenges for a child with ASD to learn and develop like children without ASD. No two cases of ASD are alike which is why it is called a spectrum disorder. This adds an extra challenge to designing spaces for children with ASD to inhabit and thrive. These children frequently suffer from sensory processing deficits in which they have a hard …

Intelligibility Of Medically Related Sentences In Quiet, Speech-Shaped Noise, And Hospital Noise, Tessa Bent, Melissa Baese-Berk, Erica E. Ryherd, Sidney Perry

Durham School of Architectural Engineering and Construction: Faculty Publications

Noise in healthcare settings, such as hospitals, often exceeds levels recommended by health organizations. Although researchers and medical professionals have raised concerns about the effect of these noise levels on spoken communication, objective measures of behavioral intelligibility in hospital noise are lacking. Further, no studies of intelligibility in hospital noise used medically relevant terminology, which may differentially impact intelligibility compared to standard terminology in speech perception research and is essential for ensuring ecological validity. Here, intelligibility was measured using online testing for 69 young adult listeners in three listening conditions (i.e., quiet, speech-shaped noise, and hospital noise: 23 listeners per …

Development Of An Instructional Course On Fire-Protective And Low-Water Landscaping In Utah, Jordan Goff

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Because of climate change, population expansion, and other factors, both wildfire and drought are becoming pressing concerns in Utah. Home landscaping can reduce risk of damage from wildfire (fire-protective landscaping) and contribute to lower water use (low-water landscaping). While it is important for homes in the wildland-urban interface in Utah to have landscaping that is both fire-protective and low-water, best practices for the two are often taught in ways that make them seem mutually exclusive. This project used existing research and best practices to develop a learning experience to teach homeowners how to implement landscaping that is both fire-protective and …
