• Abstract:
  Generally, when materials are heated (or cooled), ; they expand (or contract) to a greater or lesser ; extent. Even a material as rock-like as concrete ; is susceptible to thermal effects, and expansion ; joints are used for this reason: to allow concrete ; to expand and contract without buckling. ; Thermal expansion of concrete is especially ; important for concrete poured in massive forms. ; Setting concrete generates heat as chemical ; components react and form bonds to produce ; concrete’s characteristic strength. However, ; concrete conducts heat poorly, and the heat ; inside a massive pour may take more time to ; dissipate than the outer regions, which can cool ; faster. Contraction of outer layers over inner ; layers can cause cracks, reducing the concrete’s ; strength, structural integrity, and service life. The ; potential for thermal cracking is increased by high ; temperatures, common throughout Florida.
