Well, before starting with the topic, it is important to know that ‘formwork’ and ‘framework’ are two different terms and are independent of each other.
Considering that the difference between the two similar words is clear, let us look into some of the common concrete column formwork mistakes that need to be avoided at any cost to prevent a major disaster:
- Error in Designing:
The start point of any formwork is designing and the professional in-charge has to make sure that there is zero error in it. The design of the structure influences the formwork and therefore, in order to maintain the safety of everyone (all those present during the construction and post-construction as well), it stands crucial.
In most of the complex or complicated civil projects, a formwork designer should be hired. The experience and knowledge of the formwork professional would help avert the random guesses and ideas that breach the engineering principles and design details. Also, the expert would include the use of the right size of the appropriate material and spacing.
- Proper Pouring of the Concrete:
Concrete is a mixture of cement, stone chip (of different sizes depending on the requirement and type of structure that is to be built), and sand poured into the iron bars structure properly enclosed in a concrete column formwork. The mixture is poured into the formwork which upon solidifying acts as a beam to support the load. But mistakes happen during the process of pouring the concrete mixture. Any void or gap in the formwork is detrimental to the entire structure as there can be unequal load distribution and the entire structure might collapse.
Therefore, efforts and proper measures should be taken during the process.
- Formwork not Placed Properly:
In order to ensure that the entire structure is stable, the formwork needs to be placed on a stable and firm ground support. According to the experts associated with concrete column formwork, it is one of the most common mistakes that is often committed during any structural engineering work. The engineer and project in-charge must make sure that such a thing does not happen and hence, the support needs to be placed on stable soil.
- Leakages of Cement Slurry:
Leakages of cement slurry from the formwork take place only when the joints of the formwork are not properly tightened. This negligence at the workplace leads to not wastage of cement slurry but also renders the concrete column formwork to weaken because of the lack of required or prescribed material.
The above-mentioned are some of the common formwork mistakes that should be avoided in order to avert risks and structural failure. A thorough inspection and load assessment should be done before pouring the cement slurry into the formwork. The professional in-charge must take care of the requirements of the formwork and should erect one that has the capability to withstand the loads and stresses apart from the vibration caused during the compaction process.
