| Summary: | Abstract This study investigates the potential of incorporating alternative waste materials—limestone (LS) powder and construction and demolition waste (CDW)—in sustainable brick production under real-time curing conditions. Cement was partially replaced with LS powder in the range of 0–20% by weight, while natural aggregates were substituted with CDW at 0–100%. Experimental evaluations were conducted to assess the mechanical properties of the fabricated bricks. The results demonstrated a notable enhancement in performance compared to conventional bricks, with a maximum compressive strength of 14.99 N/mm2 observed at 2% LS and 10% CDW replacement levels. Additionally, a significant reduction in water absorption was recorded. Machine learning models, including Random Forest and Gradient Boosting, were employed to predict mechanical behavior. The findings underscore the feasibility of producing eco-efficient bricks by valorizing industrial waste within a circular construction framework. |
