To see how the nature of reinforced concrete that can cause a crack we must see the process from the beginning of the manufacture of reinforced concrete. At the beginning of the manufacture of reinforced concrete by mixing the constituent materials such as gravel, sand, water, cement, and reinforcing steel. In the process of hardening, the concrete will experience a reduction in volume from the initial volume. Generally, this is due to the water contained in the concrete mixture will experience a partial evaporation that reduces the volume of reinforced concrete.

So when conditioned when the concrete is hardened and the result of reduced concrete volume will cause shrinkage in the concrete but the concrete is allowed to shrink in the absence of loading then the concrete will not experience cracks. But on the actual condition of the field, there is no concrete that does not have loading. Because there are no beams or columns in the stand-alone building but will be joined to each other and this will make the reinforced concrete work to hold the loads on the building. So if the condition when the concrete is depreciating the volume then occurs loading, then cracks cannot be avoided.
Non-negligible temperatures can also cause cracks in reinforced concrete. The purpose of the temperature here is the temperature of the concrete mix when subjected to the pavement. Because when the mixture of reinforced concrete is experiencing the temperature hardening arising from the reaction of water with cement will continue to increase. So when the temperature of the concrete mixture is too high, when the concrete is hard, cracks often arise on the surface of the concrete.
Corrosion on the reinforcement
In fact, to anticipate the cracks that occur due to the nature of the concrete itself, the concrete is reinforced on the inside which is made of steel. Therefore, it is expected that with the reinforcing steel, the cracks resulting from the concrete properties are spread over the whole of the concrete into very small parts so that the cracks can be ignored. But if the reinforcement used during the manufacture of concrete has experienced corrosion, the reinforcement will cause cracks when the concrete is hard.
