WebApr 28, 2024 · The range of coefficient of thermal expansion of concrete ranges from 7 to 13 × 10 –6 /°C. Factors such as cementitious material … WebIn an extremely fortuitous coincidence, steel and concrete have very similar coefficients of thermal expansion. This means that when they are subject to heat (or cold) they expand (or shrink) at essentially the same rate. If this were not the case, steel would be a poor choice to reinforce concrete.
