- With the emergence of smart cities, urban spaces are increasingly expanding underground to overcome surface space limitations and efficiently manage urban lifelines. Beyond their conventional roles in transportation and utility networks, underground spaces are also attracting attention for their potential use as protective and emergency refuge facilities. This growing multifunctional role highlights the need for underground structural systems that can ensure an adequate level of protective performance while providing high mechanical performance, long-term durability, and construction efficiency through precast technologies. Lightweight Ultra-High-Performance Concrete (LW-UHPC) has gained attention as a promising material for precast underground shelter infrastructure because it can reduce self-weight while maintaining superior mechanical properties. However, its low water-to-binder ratio and dense microstructure make it vulnerable to early-age shrinkage, which may induce cracking and reduce long-term performance. This study evaluates the application of Superabsorbent Polymer (SAP) as a strategy to mitigate this shrinkage without compromising the lightweight advantage of LW-UHPC. The effects of SAP dosage by binder mass (0, 0.1, 0.2, 0.3, 0.4, 0.5, and 0.6%) on compressive strength and unit weight were analyzed. The results indicate that while both properties generally decreased with increasing SAP content, a dosage range of 0.1–0.2% was optimal. In contrast, SAP dosages exceeding 0.4% led to a sharp decline in compressive strength. These findings suggest that SAP can be an effective additive for shrinkage control in LW-UHPC for precast underground shelter infrastructure, provided that its dosage is carefully optimized to minimize loss of mechanical performance.
