What to do if you catch a crack in the slab of the building

News Desk: Slab is a flat thin cast made of rod-cement concrete. Construction is almost impossible without a concrete slab. Currently most of the building slabs are reinforced concrete slabs. However, cracks in the slab are often seen. This crack occurs due to various types of defects. Let's not know what to do if you catch a crack in the concrete slab?

Causes of cracks: The top and bottom of the slab are usually parallel. Cracks may appear in this slab for various reasons. There are two types of cracks in any building - structural and non-structural cracks. Cracks in concrete slabs include structural cracks. Structural cracks are again due to two reasons- design defects and construction defects.

Design Errors: This type of problem occurs when the structural design of the building is not done properly. Properly structured design requires a thorough understanding of building use and building codes. Accurate calculation of all types of loads, wind, earthquakes and other lateral loads in the building.

It is often seen that buildings built for one purpose are used for another. If you do office or factory work by designing the structure by calculating the residential load, then there may be a problem of cracking due to the difference in the load. Therefore, one of the most important steps in building construction is to test the soil of the site concerned.

If the soil is not tested properly and the foundation is laid incorrectly, the building often collapses. This caused cracks in the slab. Moreover, cracks also occur due to errors in the size and design of the rod. So the rod should be designed according to the code.

Construction Defects: In many cases, as the concrete of the slab is not clearly covered, water vapor or water enters and the quality of concrete and reinforcement deteriorates and cracks occur. If more rods are used at the junction of beams and columns, the concrete will not penetrate properly but will catch cracks.

Another big reason is not mixing concrete properly and using concrete mix of wrong proportions. Not only that, the quality of bricks, sand, cobbles, etc., is defective, but cracks appear in the slab. Also open the shuttering before the right time. This causes the slab to rupture due to the load falling on it before the concrete reaches full strength.

Remedy: Cracks can be easily avoided by following certain rules before making slabs and during casting. When making reinforced concrete slabs, the following rules should be followed:
1. Proper adherence to the building code when formulating the structural design of the building.
2. Checking whether the ratio of concrete mix is ​​correct.
3. Build the structure according to the soil test.
4. To construct the structure by calculating the load of the building.
5. Laying the foundation considering the disaster according to the site.
. Properly follow the rules when opening the shuttering.
. Ensuring the quality of concrete components.

Slabs are considered the heart of any building. So if the construction of the slab is not correct, the construction of the whole building will be in vain. As a result, it is important to construct reinforced concrete slabs in accordance with the correct rules and under proper supervision.
