The concrete or the compensation joints are used when the concrete expands or contracts while the temperature. These joints are normally used for preventing the concrete to shrink when individuals do the forming, sawing, tooling and placing the joint formers. The pre-planned cracks in the form of the joints will offer a better concrete floor at the specified locations where the cracks can be checked. At times, the material and the width of the joints are used in enhancing the performance of the material and help the primary material to expand and contract. The joints also prevent the further damage to the items.
What is special about the concrete contraction joint?
These joints are mainly created in the area that is weakened and the joints are useful for regulating the cracks that occur in the straight line. These joints are placed in the vertical or horizontal manner to produce something that looks like the square. They never exceed the length-width ratio of 0.5 to 1. The joints are placed at the distance that is equal to 24-30 times of the thickness of the slab used on the floors.
These concrete joints can be installed on the concrete surface during the time of replacement. The joints are placed on the hardened concrete surface. It is very important to know that the longer the potential of cracks is delayed; there will be higher chances of cracks on the floors.
The expansion joints
The concrete expansion types of joints are used for separating the slabs and concrete from the other parts of the structures. These joints allow in the free movement between the surfaces to reduce the cracking. This allows in the heat expansion and also in the contraction without letting any type of stress in the system.
Why you need the construction joints?
These concrete control joints are used in the areas of circumstances where there are two placements meets. These are normally installed at the end of the time. These joints are made by the professional engineer. You can get the strength and bond as you require when you customize these points. These points are versatile and help in holding two surfaces.
These concrete joints are placed keeping in mind certain tips. You can use the maximum spacing which is about 24-34 times thickness of the floor or slab. When using the contraction joints in the groove, it is better to keep a minimum half quarter thickness.
