← TechnologyWhich risk increases when sustained high tensile force compromises rebar anchoring?
A)Premature concrete spalling occurs✓
B)Shear capacity unexpectedly increases
C)Carbonation's reaction rate decreases
D)Alkali-silica reactions are greatly minimized
💡 Explanation
Premature concrete spalling increases because sustained tensile stresses lead to bond slip at the rebar interface, inducing cracks; therefore, spalling occurs, rather than improved shear capacity or altered chemical processes within the intact concrete matrix.
