Avoid these 5 mistakes when concreting during winter
Winter is a complex season when it comes to construction, and contractors can face various difficulties, for clear reasons. Also, construction doesn’t stop depending on the weather, which is why taking extra precautions in winter is vital to the entire process. Due to the fluctuations in temperature, the curing process for concrete results in irregularities. This makes it extremely important to prepare essential protection for fresh concrete, and ensure adequate equipment and precautions are in place before the cold weather kicks in.
It is really important to know the ‘dos and don’ts’ of the concreting process to avoid structural setbacks and unnecessary delays.
Here are 5 common mistakes that you should avoid, at all costs, when concreting during the winter:
Concrete on frozen ground
During the process of pouring the concrete, the placement of the slab plays a big role in determining the concrete curing conditions. Thawing frozen ground will settle it, but cause the concrete to crack. This can also cause the top half of the set to cure faster than the lower half leaving the concrete closest to the ground still soft. Differences in temperature throughout the concrete can cause it to settle inadequately and thus, crack and result in major structural issues.
Using warm tools
As much as keeping the concrete warm is vital to the construction process, it is also important to make sure the tools don’t freeze or become extremely cold during winter months. Any concrete that comes in contact with cold tools can create alterations that will cause problems when it comes to the strengthening of the structure. Prior preparation for this can be taken to make sure the process is seamless.
Improper use of portable heaters
When it comes to the strengthening of the concrete structure, the temperature needs to remain consistently warm. Drops in temperature can cause the concrete curing process to halt altogether, causing delays and unnecessary wastage of resources. Portable heaters can help in monitoring the temperature and providing the concrete with adequate heat. While this is a good option, keep in mind that overheating can also cause the concrete to become weak.
When it comes to using natural resources in construction, daylight plays a big role, since its abundance can benefit contractors in many ways. But with its advantages, it is also essential that prior knowledge of daylight timings is considered. During winter, days are shorter and so, not using the time efficiently could lead to concrete curing issues. Using heaters could help in the concreting process, before or after day time.
Not using temperature monitoring sensors
In the winter months, it is extremely important to keep a watch on the temperature levels. This can play a big role in building the strength of the concrete structure. Many problems can crop up if proper attention is not given to monitoring the temperature. Problems like the concrete freezing, inferiority in the strength of the structure, rapid temperature changes, and improper curing procedures can lead to major delays, causing contractors both time and money.
Getting good quality cement is also important. Emami is one of the best cement brands in India whose Portland Pozzolana Cement (PPC) is ideal for high-performance concrete. Being one of the leading cement companies in India, Emami DoubleBull Cement is a brand you can trust.
