Barrett

Barrett, The Honors College at Arizona State University proudly showcases the work of undergraduate honors students by sharing this collection exclusively with the ASU community.

Barrett accepts high performing, academically engaged undergraduate students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project which is an opportunity to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is supervised and defended in front of a faculty committee. Students are able to engage with professors who are nationally recognized in their fields and committed to working with honors students. Completing a Barrett thesis or creative project is an opportunity for undergraduate honors students to contribute to the ASU academic community in a meaningful way.

This thesis investigates the feasibility of using recycled ceramics as the aggregate in concrete, as an alternative to natural rock aggregates. The study evaluates the mechanical properties of concrete made with recycled ceramics and compares them with those of traditional concrete. The research involved laboratory experiments to determine compressive strength and displacement. The results show that the concrete made with recycled ceramics exhibited higher compressive strength and lower maximum displacement than traditional concrete, which means it acted more brittle. However, when the recycled ceramics were used to replace only 50% of the rock aggregate, the compressive strength decreased while the maximum displacement stayed the same, though the study concludes that a larger sample size is needed for more reliable results. Based on the findings, the thesis concludes that while the use of recycled ceramics in concrete may not be suitable for structural concrete, it could still have potential as a sustainable building material in non-structural applications.

The preceding paper analyzes the effects of UV radiation in plastic reinforcement and its effects on the fracture properties of cement-based materials. Three point tests were performed on notched beams, which called for the consideration of the Type II Size Effect. A comparison of the ductility of beams with and without polyethylene plastic powder reinforcement was done through the calculation of the fracture parameters Gf and cf, which represent the initial fracture energy and the characteristic length respectively. Although there was an observed increase in ductile behavior and properties in beams with polyethylene reinforcement, there did not seem to be a significant effect caused by the UV radiation. The hydrophilicity of the polyethylene powder was successfully increased through UV radiation and validated through water retention tests, which showed that the UV-treated polyethylene was retaining more water than the non-treated polyethylene, yet there was no extra increase in ductility of the cement beams compared to using non-treated polyethylene. The Type II Size Effect analysis was performed and compared to the stress analysis results of the experiment. For future research, it is recommended that a higher volume of polyethylene per 1000 grams of cement powder be used, as well as increasing the strength of the UV chamber to achieve a larger increase in the hydrophilicity of the polyethylene. Also, perhaps using more precise equipment to cut the notches in the beams would be helpful in ensuring that all specimens are identical and there is no error in notch depth caused by inaccurate use of the hacksaw or radial saw. Further experiments will be conducted.

This Barrett creative project includes the structural design of a coffee shop using recycled shipping containers in Phoenix, Arizona. Repurposing old shipping containers into commercial and residential buildings has become more popular. Even here in Arizona, buildings have already integrated shipping containers into their design. Shipping containers add a unique character to the architectural design of the building and at the same time cut costs of construction due to their low prices. With using the shipping containers as building materials, there is a positive impact on the use of the structures in builds. The uniqueness of using shipping containers is what sparked my interest to design a shipping container coffee shop. For my creative project, I designed the coffee shop using the already structurally sound core of the shipping container to my advantage. However, when adding modifications to the structure, the materials of the structure were analyzed to ensure the design could take the modifications. I have taken my love for structural design, the environment, and coffee and brought it to life. Through this project, I have a better understanding of how much thought goes into designing a building and have a deeper understanding of the codes that structural engineers must follow to design and analyze buildings.
