All About of Cold Joint in Concrete | What is Cold Joint Concrete | Effect of the Cold Joint Concrete | How to Avoid Concrete cold Joint | Concrete Cold Joint Repair
The Cold joint in the concrete will cause the deterioration of the steel reinforcement in the concrete.
The cold concrete joints reduce the strength and durability of the structure.
The aesthetic appearance of the surface of the concrete gets affected due to the presence of the cold joint concrete.
The cold concrete joints may cause various problems in the concrete such as reduction in the strength of concrete and water leakage.
The cold joints in the concrete do not affect the structural ability of the structure but it affects the appearance of the building.
The cold concrete joints are considered weak joints but the cold concrete joints are not always weak. For this, it is necessary to provide the extra length of steel reinforcement in the concrete so that another reinforcement should be attached to it to makes it structurally stable.
If the concrete is in the compression phase, then there will not be any structural problem occurs but if the concrete is in the tension phase, then it may lead to the failure of the concrete.
While placing the layer of the concrete the concrete which is placed before must have a rough unfinished surface.
If the previous surface is hardened and not rough enough then make the surface rough with the help of tools so that there will be a good bonding between the two consecutive layers. This will avoid the formation of cold concrete joints in the concrete.
The concreting should be done in layers and intermix each layer properly with the previous layer with the help of a vibrator.
The pouring of the concreting should start from the end corners and then move forward towards the center.
While executing the concreting operations at extremely high temperatures use retarding admixtures which increases the setting time of the concrete.
The construction of the sloping elements such as rafts and stairs the concreting should be started from the bottom and then move towards the top.
