Abstract

Concrete curing under hot-weather exposure requires sustained surface moisture while minimizing repeated waterapplication. This study develops and evaluates a two-layer external curing blanket comprising a polyethylene (PE) top sheetand a superabsorbent polymer (SAP)-infused needle-punched nonwoven polyester layer. Ten PE sheets, three sodiumpolyacrylate SAP grades, and three nonwoven fabrics were screened sequentially according to optical transmittance, SAPmorphology and absorption behavior, fabric absorptivity, SAP-fiber integration, and qualitative seven-day surface-wetnessobservations. The selected configuration (S7 PE/SAP 3/GT-80) was then demonstrated using a 1 × 2 m2 outdoor prototypeand compared with conventional wet burlap curing. The blanket-cured concrete produced a numerical mean core strengthof 36.5 ± 1.1 MPa versus 34.9 ± 0.63 MPa for burlap, corresponding to a 4.6% higher mean. Qualitative photographs indicatedlonger visible surface wetness and fewer visible surface defects for the blanket configuration. Total supplied curing water was20 L compared with 180 L for burlap, corresponding to an 88.9% reduction on the reported water-supply basis. These findingsdemonstrate that SAP-infused blankets provide a sustainable and efficient solution for concrete curing, particularly in hotand water-scarce environments
