Analysis of Construction and Post-Construction Behavior of Carbon Capture Concrete: Stadium Drive Garage

Abstract

Concrete is a fundamental material in construction but is responsible for a significant amount of global CO2 emissions. To address this issue, sustainable methods like carbon sequestration are being explored to reduce concrete production's carbon footprint. However, to implement such techniques, it is necessary to understand their impact on concrete properties and performance thoroughly. Literature on the behavior of carbon sequestering concrete in a real-world setting is limited. This thesis aims to investigate the performance of CO2-injected concrete during the construction and post-construction phases to provide a foundation for future research on this technology's application. The study uses data from Fiber Bragg Grating sensors installed in a garage’s column and slab to analyze the behavior of CO2-injected concrete. To understand the behavior of the concrete, temperature and strain changes during construction and post-construction were compared for both members, with a more thorough structural analysis performed on the column. The findings reveal that CO2-injected concrete behaves similarly to traditional concrete during construction, while the post-construction behavior needs to be further analyzed with larger loads.
