These cracks may occur in reinforced concreteelements after the hardening state. Flexural cracks are vertical cracks that develop at the tension zone of the member up to their neutral axis. Width of these cracks are usually wider at the mid-span of the member. This is because the maximum strain in reinforcement occurs at this zone. Flexural cracks ...
Drying shrinkage is also a crack that occurs after hardening of concrete. It happens due to the reduction of concrete volume when the water content in the concrete evaporates. As the water content increases, the rate of shrinkage rises equivalently. Drying shrinkage may be a full-length cracking. Usually contraction joints are placed to predetermin...
Concrete will contract and expands with changes in moisture and temperature. As long as these contraction movement is free to take place tensile stress will not develop in concrete members. But in reality, movement of this contraction will be restrained due to internal or external restraints, which causes development of tensile stress, leading to c...
Plastic-shrinkage cracks are common in slabs. These cracks are comparatively short cracks. When the evaporation of the moisture at the surface of concrete is more than the availability of the rising bleed to fill the surface moisture, if this process happens before concrete attaining its tensile strength, the volume change may cause cracks. The key...
Cracks can also be caused by alkali- aggregate reaction, sulfate attack, settlement cracking, freezing and thawing (D-cracking) of saturated concrete, or corrosion of reinforcing steel.
