Barrett, The Honors College Thesis/Creative Project Collection
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.

The environment today is facing concerns over accumulation of plastics in landfills as well as excessive CO2 emissions. Containers and packaging take up approximately 15 million tons each year, and accumulations such as the Great Pacific Garbage Patch are entering the oceans. Work has been done to alter and treat polyethylene plastic to be added to cement mixtures. This is done to increase bearing capacity and ductility of concrete in addition to decreasing carbon emissions and plastic waste.
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.
