Reasons Why Concrete Fails

»Posted by on Mar 23, 2020 in Uncategorized | 0 comments

Nowadays, one of the best man-made products for construction is concrete. It has become extremely well-known because of its excessive durability and heat-proof properties that it can offer in construction. It’s one of the strongest man-made materials. However, just like any other thing, it still has its weaknesses. If proper measures aren’t taken, there’s always a chance for concrete failure.  

There are a couple of various reasons why concrete fails. Here are a couple of things that professional concrete contractors Bentonville AR avoid to prevent concrete failure: 

Concrete Softening Because of Sulfate Attack 

Concrete softening can be caused by water that contains a high level of dissolved sulfate. The reason for this is the crystallization and expansion. When this happens, there’s also a chance of internal sulfate attacks because of high curing temps.  

To prevent this, you need to utilize treated water with low levels of dissolved sulfate. 

Concrete Overloading 

This is a problem that’s quite more popular. Various types of concrete exist that present different levels of durability. The right form of concrete should be utilized if the concrete is being utilized for constructing a building that’s going to support a massive load. On a couple of occasions, contractors utilize the wrong form of concrete to cut costs and to get the project completed faster. When massive loads are exerted on the building, the concrete will eventually fail. 

Concrete Cracking Because of Alkali-Silica Reactions 

On particular occasions, aggregates that contain alkali and silica result in a gel formation that can crack concrete. This is particularly true when exposed to humid conditions. While not common and not the primary form of concrete failure, it’s still a way of concrete failure that you have to consider. It produces crumbles and potholes of buildings, concrete pavements, and much more.  

Poor Finishing That Results in Trapped Air 

Another popular problem when applying the concrete is poor finishing. A particular amount of air gets trapped in between the concrete because of this poor finishing. Trapped water and air lowers the durability of the slap at particular points and can prove to be very risky because it’s weak concrete.  

To prevent this type of failure, you’ve got to keep air content below 2%. To guarantee that the concrete is not allowed to prematurely finish, a contractor should take care of the concrete.  

Wrong Raw Materials That Result in Poor Concrete Quality 

On a couple of occasions, the raw materials utilized can cause concrete failure. The result will be poor concrete quality if the improper raw materials are used. Also, the mixture is vital. One of the most important aspects when it comes to concrete is the ratio of how every raw material is added. Typically, shortcuts to save money and time result in poor concrete quality that is easy to break and is void of the needed durability.  

A professional concrete contractor should know how to choose the right raw materials. They should also know how to properly mix these materials together to achieve the ideal durability for the project.
