Reasons for Concrete Cracks
The first step in avoiding the issue is learning what makes a concrete crack. The cracks must be minimized since they weaken the strength of concrete and make it less visually appealing. But, if you already found a crack, then call for a professional concrete repair service. Some common causes of cracked concrete are discussed in this article. To ensure that you get uncracked concrete, read on.
Excessive Weight Causing Cracks
As the name suggests, such cracks occur when the concrete carries too much weight from above. Concrete is a very sturdy material; however, it has its weight restrictions and can crack with a heavy load. In the early days of cure, the weight overloading cracks are most probable in cement that has not yet been solidified. Therefore, we suggest that a person should wait at least 48 hours before walking or driving on the concrete.
Due to Weather
Temporary changes in weather may lead to cracks in concrete. It usually occurs as a result of freezing and thawing. When the concrete has excess moisture, it expands when frozen cracking the concrete. Such cracks, therefore, weaken the concrete and make it susceptible to further cracking because they offer an avenue for more moisture.
Expansion Cracks
Concrete will expand in extremely hot conditions, putting a lot of strain on the slab. The concrete will press against anything in its path as it expands. The resultant force will cause the concrete to crack if neither is flexible.
Not Perfectly Dry
This may manifest as fine surface cracks popularly known as ‘crazing cracks’. Although the crazing cracks are not good to see, they do not make a significant reduction in the strength of the concrete.
Plastic Shrinkage Cracks
The most common cracking type, plastic shrinkage cracks, occur in concrete. These are the ones that take place when the concrete is exposed to an extremely fast loss of moisture due to changes in temperature and humidity. Evaporating moisture from the surface of the concrete in a plastic state causes the formation of porosity due to large voids left behind, consequently making it weak and susceptible to cracks.
