← TechnologyWhich risk increases in prestressed concrete due to incorrect grouting?
A)Strand corrosion from moisture ingress✓
B)Increased concrete compressive strength values
C)Improved stress distribution uniformity achieved
D)Reduced concrete creep and shrinkage rates
💡 Explanation
Incorrect grouting increases the risk of strand corrosion because chloride ingress accelerates oxidation via the electrochemical process called crevice corrosion, therefore reducing the structural integrity rather than enhancing the concrete's properties inside.
