摘要

High-Performance Concrete (HPC) is a sophisticated construction material with superior qualities compared to traditional concrete. Due to its extensive cement usage, HPC is known for its considerable environmental impact. This study investigates how integrating Recycled Brick Powder (RBP) as a partial cement replacement in HPC formulations can decrease cement utilization and reduce environmental effects. RBP was ground for varying durations—30, 60, and 90 min—to evaluate the impact of particle size variations on the properties of HPC, but HPC_90 was excluded from long-term testing due to comparable performance to HPC_60 and higher energy consumption. Initiating with a baseline formulation, this research is dedicated to examining how High-Performance Concrete (HPC) is enhanced by the addition of Recycled Brick Powder (RBP). The study focuses on the impact of RBP on the mechanical and physicochemical properties of concrete, utilizing both destructive and non-destructive evaluations. Additionally, microstructural examinations are performed to reveal the changes at the microscopic level caused by RBP, providing critical insights into how RBP interacts with conventional concrete components. This research also includes specific tests like porosity and water absorption to determine the influence of RBP on concrete’s strength under conditions. Findings from the study indicate that Recycled Brick Powders (RBPs) milled for 30 min significantly enhance the mechanical properties of concrete, achieving compressive strengths around 100 MPa after a curing period of 90 days. This underscores the potential of RBPs for applications in high-performance concrete. Furthermore, environmental analyses show that using 10% RBP can lead to substantial reductions in energy usage and CO2 emissions, thus supporting the sustainability of construction practices. These results highlight the dual benefits of RBPs: they not only strengthen the structural properties of concrete but also contribute to lowering environmental impacts, fostering a more sustainable construction sector.
