Thermal Expansion and Contraction of Slabs on Grade

1999-1-1 · A general value for concrete''s coefficient of thermal expansion is about 5.5 millionths/° F. If an unrestrained, 100-foot-long slab on grade was exposed to a 100° F temperature drop throughout its cross-section, it would contract about .66 inch (100 feet x 12 inches/foot x 100° F x .0000055). Since the slab is restrained by friction between
