Implication

Utilization of bayer red mud improved compressive strength and reduced heavy metal concentrations in mortars, indicating its potential in sustainable construction.

Key Points

Adding bayer red mud maintains compressive strength at lower replacement levels, promoting sustainable practices.
At 0.5% to 5% BRM incorporation, compressive strength stayed comparable to controls while exceeding thresholds for heavy metals.
Microstructural analysis using XRD and SEM confirmed bayer red mud acts as a nucleation site in hydration reactions.
These findings suggest that bayer red mud supports eco-friendly solid waste management in the alumina industry.
