Cracks in concrete walls and slabs are a common occurrence.

Thermal cracking in concrete walls.

The reason of thermal cracking is excessive temperature differences within a concrete structure or its surrounding environment due to the temperature difference the cooler portion contracts more than the warmer portion which restrains the contraction. Thermal cracking of concrete and prevention temperature difference within a concrete structure may be caused by portions of the structure losing heat of hydration at different rates or by the weather conditions cooling or heating one portion of the structure to a different degree or at a different rate than another portion of the structure. Walls exposed to the outdoors have a greater chance of thermal expansion and contraction and retainage of moisture than walls located indoors or in protected areas. Control joint cracks in concrete.

These cracks mainly appear after 2 to 3 years of construction. Foundation walls are normally designed as reinforced concrete. However a footnote warns that with time a significant portion of the cracks in a structure can exceed these values. Early age thermal cracking usually termed as early thermal cracking is a phenomenon in concrete structures caused by excessive tensile strain in a concrete section above the tensile capacity of concrete as a result of restraining thermal contraction or due to differential temperature within the cross section.

Early thermal cracking occurs due to the excessive tensile strains in the concrete than its capacity and tensile strains are developed due to the thermal contractions or with the variation of temperature within a section. Unlike thermal expansion and contraction dimensional changes in brick due to moisture are irreversible. When neither has the ability to flex the expanding force can be enough to cause concrete to crack. Cracking can not be prevented but it can be signifi cantly reduced or controlled when the causes are taken into account and preven tative steps are taken.

Concrete temperatures which are over 10ºf higher than the daily high or low. Or see this. They appear in fl oors driveways walks structural beams and walls. The higher that concrete temperatures are above ambient temperatures the greater is the risk of thermal cracking.

Thermal expansion of materials for a table of the coefficient of expansion of common building materials including brick concrete mortar and stone. Most cracks should not be a cause for alarm. Just like a balloon heat causes concrete to expand. When concrete expands it pushes against anything in its way a brick wall or adjacent slab for example.
