• ### Thermal Expansion of Concrete and Reinforced Concrete

The thermal coefficient of expansion of concrete and reinforced concrete have been determined under short-term steady state temperatures, - IO0 to 150 F (-73 to 66 C). Specimens were cured both satuuratad and air-dried in the laboratory and tested at 7, 28, and 84 days and at I year.

• ### Thermal Expansion and Contraction of Slabs on Grade

1/1/1999 · 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).

• ### How to calculate thermal expansion – x-engineer.org

Linear thermal expansion applies mostly to solids. Knowing the initial length L 0 [m] of a given solid (e.g. metal rod), the temperature difference ΔT [ºC] and the coefficient of linear expansion of the solid α [1/ºC], the change in length ΔT [m] of the solid can be calculated as: $\Delta L = \alpha \cdot L_0 \cdot \Delta T \tag{1}$ The change in length is directly proportional with the
