Abstract The increasing risk of fire hazards and the environmental burden construction demolition (C&D) waste necessitate sustainable, fire-resistant building materials. This study investigates potential recycled aggregate concrete (RAC) reinforced with fibers to enhance high-temperature performance while promoting utilization. In first phase, mixtures 0%, 25%, 50% (labeled RAC00, RAC25, RAC50) were evaluated at 23 °C, 300 600 °C. RAC00 exhibited a 16% reduction in compressive strength °C over While RAC25 initially showed 10–30% decrease compared conventional room temperature, it only 1% decline 28% making most effective composition for further study. second steel (SF) polypropylene (PPF) incorporated into yielding substantial tensile improvements: RAC25-SF increased by 5.6% 24.8% 28.3% RAC25-PPF 12.5% increase but declined higher temperatures, 9.9% 32.9% SF enhanced across all PPF reduced above 200 Fiber additions improved ductility, toughness, moisture retention, mitigating crack propagation under heat. Statistical modeling using ANOVA response surface methodology (RSM) confirmed high model validity (R 2 > 0.80). concludes that offers heat-resistant material, addressing both resilience C&D challenges.

In the process of repairing cracks in underwater buildings, repair effect is not ideal due to poor dispersion resistance and low retention rate slurry. light this, this study created a new magnetically driven cement-based (MDCGM) grouting material research that can be used building cracks. paper, quadratic regression model was established with fluidity (X) as response values bentonite content, water-cement ratio, Fe3O4 powder flocculant content influencing factors. The has good fitting reliability. Finally, stone body's damage constitutive equation under various factors determined. This article focuses on slurry compressive strength body, conducts an analysis microstructure. Meanwhile, it establishes body. results show primary secondary relationships influence value X are: Water-cement ratio > Flocculant Bentonite content. between 212.5 mm 437.5 mm. When bentonite, are 1%, 3%, 5% respectively, increases from 10 15% 20%, 3-day grouted body by 6.02% 33.40% 7-day 2.65% 5.67% respectively. indicates Fe₃O₄ significantly improve early-stage consistent experimental predict mechanical properties material.
