This study evaluates the effectiveness of different curing methods on the compressive strength and water absorption of 62 MPa High-Performance Concrete (HPC). Using an experimental research design, 54 concrete specimens were tested across three curing regimes: Water Curing (Group A), Plastic Membrane Curing (Group B), and Curing Compound (Group C). Data analysis was conducted using descriptive statistics, graphical trend analysis, and percentage difference analysis to monitor the strength development at 7, 14, and 28 days. Results revealed that while membrane-based methods (Groups B and C) showed satisfactory early-age strength, only Water Curing (Group A) successfully achieved the target design strength, reaching a final average of 62.47 MPa. The trend analysis showed a significant deceleration in strength gain for the alternative methods after 14 days, with the curing compound showing a 13.77% strength reduction compared to the control group. The findings conclude that continuous external moisture is critical for the full hydration and structural integrity of high-strength concrete mixes.
