Which risk increases when improperly spaced rebar inhibits concrete consolidation around steel reinforcement?

A)Reduced bond strength between rebar/concrete
B)Increased thermal expansion coefficient
C)Enhanced resistance to shear forces
D)Decreased susceptibility to chloride ingress

💡 Explanation

When rebar spacing is too tight, it hinders proper concrete consolidation by preventing vibrator penetration, increasing the presence of voids around the steel, which reduce bond strength. Therefore reduced bond occurs, rather than impacts to thermal expansion, shear resistance, or chloride ingress all of which require different mechanisms.
