ABSTRACT

To address the demand for green, adaptable building materials in urban renewal’s existing building renovation and public space transformation, and solve traditional stone-like materials’ defects (long construction period, poor adaptability, low solid waste utilization), this study optimizes inorganic composite stone-like cast-in-place technology and evaluates its performance. Industrial solid wastes (steel slag, recycled construction aggregates) serve as main raw materials; composite cementitious systems and functional admixtures are developed, with key process parameters determined via orthogonal experiments. Results show that at 72% solid waste replacement rate, 0.28 water-binder ratio, 0.4% retarder content and 20–25℃ pouring temperature, the material’s 28-day compressive/flexural strength reaches 105/9.8 MPa, setting time 4–6 h, meeting on-site construction requirements. It exhibits excellent durability, with 8.2% strength loss after 50 freeze-thaw cycles and grade-4+ stain resistance. Engineering verification confirms 40% higher construction efficiency, 35% lower cost and 1.2 t/100 m2 carbon emission reduction versus traditional dry-hanging. This scheme offers green, efficient technical support for urban renewal, with significant engineering and environmental value.
