Abstract: To fully utilize solid waste such as boiling furnace ash and construction waste, a high-performance concrete based on pre-treated construction waste and boiling furnace ash was developed. The mechanical properties, resistance to chloride ion penetration, resistance to freeze-thaw cycles, and hardening mechanisms of the concrete were analyzed. The research results indicated that when the substitution rate of boiling furnace residue for fly ash was 50%, and the unit cubic mass ratio of fine-grained to coarse-grained construction waste was 460.00 kg/m³: 562.22 kg/m³. The concrete exhibited maximum compressive strength and elastic modulus. Specifically, the compressive strength and elastic modulus of HF3 on the 28th day were 37.51 and 3.51×10⁴ MPa, respectively. The resistance to chloride ion penetration of the concrete increased with the content of boiling furnace residue, and HF3 on the 28th day had an "extremely low" chloride ion penetration grade (electric flux was 113 C). The relative mass, relative compressive strength, and relative elastic modulus of HF3 showed the least loss with an increase in freeze-thaw cycles. The related fitting equation for freeze-thaw damage degree D, y=a×b^x, showed that b parameter for HF3 was the smallest at 1.008 76, indicating its strongest resistance to freeze-thaw cycles. The hardening mechanism revealed that the addition of boiling furnace residue provided more active SiO₄⁴⁻ and AlO₄⁵⁻ substances in the concrete system, increasing the content of six-coordinated Al (AlO₆) in ettringite (90.35%) and the content of O 1s bridging oxygen bonds (99.90%) and Si 2p binding energy (102.05 eV) in C—(A)—S—H. Furthermore, the microstructure of HF3 exhibited fewer cracks, revealing a denser solidified structure with a significant presence of calcium aluminate and C—(A)—S—H binding together.
