Few Reasons Why Concrete Cracks

Concrete is one of the economical kinds of engineering building material that is a combination of closely bound particles. It is usually a blend of natural aggregates like crushed rock, sand or gravel that is bound together with the help of a hydraulic binder. If used rightly, it might last longer. However, you should remember that even concrete doesn’t last forever. After certain time span, it starts deteriorating and needs to be repaired.

You might have noticed cracks in the sidewalks, driveway or in other places and wonder why this cracking is happening. Was the material used of low or substandard quality?

Concrete slabs are usually very difficult to maintain due to its continuous use and needs appropriate care to maintain it in a good condition. However, concrete is the most durable and productive kind of product that can be used for your home. Though concrete is believed to be durable when taken care, yet it might be difficult to maintain it without even a single crack. If you are wondering why concrete cracks then mentioned below are a few reasons.

Why concrete cracks?

Excess amount of water in the mixing might lead to possibility of a concrete break. When it comes to concrete, they don’t require much water to achieve strength. Water is added to the mix to make it workable. However, excess amount of water might make it lose strength and reduce the chances of making a perfect settlement.

Shrinkage

It is another common kind of cracking. As concrete start drying, the strength of the settlement increases. This happens after evaporation of excess water mixed in the blend.

Concrete drying faster than usual

The sooner the settlement dries up there is more chance of growing cracks around the settlement. The chemical reaction that takes place to convert the liquid into solid state requires water. This type of reaction usually takes days to weeks after concrete is poured.

Lack of controlling joints

Control joints are present to help concrete settlements in places it is allotted. The joints should be there to help slabs with depth and it shouldn’t be more than 2 – 3 times than the thickness of the concrete. Therefore, having a wrong controlling point might work negatively, thus ruining the cracks in the concrete.

Concrete is today one of the widely used man-made engineering material than other building materials including plastic, steel, aluminium, wood etc. Also, the performance, price and effectiveness of concrete is nowhere close to the other materials.
