Water Penetration Test on Specimens Cured in the Same Way as Precast Concrete Products

Key Points

• The aim is to assess moisture penetration rates in precast concrete products cured identically to evaluate their durability against prediction models.
• Measured moisture penetration rates using 71 specimens cured with steam curing.
• Compared results with established prediction formulas for conventional concrete durability.
• Analyzed variations in materials, mix designs, and curing conditions.
• No strong correlation was found between water-cement ratio and compressive strength.
• Individual moisture penetration coefficients were necessary for each curing condition assessed.
• Existing prediction formulas were not effectively applicable to precast concrete.
