Concrete construction requires a high level of precision, but the post-tensioning phase of the process requires an even higher level of accuracy. Each of these statements is undeniably true. For this reason, it's vitally important that you know how to avoid several post-tension mistakes that can cause your concrete structures to fail. Whether you're a seasoned concrete contractor or you're just started out, a quick refresher is always helpful.
1. Overlooking Shortening
A leading cause of concern is the mistake of forgetting about any shortening issues that might occur. If you recognize any signs of shortening around the post-tension assembly don't ignore the problem. Shortening can affect construction not just in terms of the overall look of the project, but the issue can also cause structural concerns.
The problem is often the result of shrinkage that occurs during the drying time. The best way to avoid shortening is to factor in any variances during the design phase so that you can ensure you are pre-accommodating for any shortening that could naturally occur.
2. Not Performing Adequate Finishing Steps
When it comes to post-tension accuracy, the finishing process is by far one of the most critical phases of the entire installation process. Ensure your finishing process includes everything from examining the stressing pocket to removing any strand tails. If your project's design plans do not involve finishing steps, the overall quality of the construction is at risk for premature failure.
Proper finishing around the tension components preserves the structural integrity of the structure. A great way to avoid this mistake is to assign a member of the team with the specific duty of performing the inspection process once the initial installation phase has been completed.
3. Not Calculating the Deadload
Calculating the dead load is a tedious process at times. However, if you have worked in the area of concrete construction for any time — you know that it's a necessary step. Make sure you don't fail to calculate this figure on your project. Calculating the deadline is essential in order to ensure that the weight ratio is balanced with the post-tension structures.
An incorrect balance most always leads to complete failure of the concrete structure. Calculate the dead load during the design phase and then again just before the project kickoff to ensure the information is accurate.
The more effort you put into minimizing these and many other mistakes, the smoother your construction process, but also the better the quality of your finishing projects. Whether you're designing a small structure or a massive building, make sure you partner with a reputable post tension supplier for the best results.
