← TechnologyWhich risk increases when concrete pour rate accelerates in rebar-reinforced bridge deck?
A)Increased hydrostatic pressure on formwork✓
B)Decreased concrete hydration reaction rate
C)Reduced rebar electromagnetic interference shielding
D)Elevated steel thermal expansion stresses
💡 Explanation
Increased pour rate elevates hydrostatic pressure on the formwork because increased fluid loading overcomes the membrane reinforcing action, therefore increasing the likelihood of bulging and potential failure of the bracing, rather than impacting hydration.
