Benefits and Drawbacks of Concrete as Construction Material

Concrete is the most widely used material for construction purposes because of the unique benefits that it provides unlike most other construction materials. The major benefits that concrete has are listed below:

Economical:
Comparing many other construction materials like steel and polymers that are available in the market today, concrete is the most affordable one. Concrete is cheap and available in every market around the world from where we can even check various prices offered by different companies and buy the one within our budget. Concrete is inexpensive because of its composition which includes cement, water and stones. The major ingredients of concrete can be bought at very low prices from the local markets.

Formed in different shapes:
When the concrete is in liquid and flowable state, it can be poured into your desired frame configurations easily. Once the concrete solidifies in the frameworks inserted, it will take up the shape that you desired to achieve from it. The desired shapes can then be used for the construction purposes. It can be used for forming complicated shapes which will be rock solid and durable.

Hardens at room temperature:
Concrete does not require any change in temperature to harden and gain its strength. It can harden at its best at room temperature itself because of the presence of cement as one of its major ingredients which is a low-temperature bonded inorganic construction material. Concrete can be used in every temperature and weather conditions and can also be used with other mixtures when required.

Excellent water resistance:
The chemicals like sulphates, chlorides and carbon dioxide in water can cause corrosion in concrete but, when it is compared to wood or steel, concrete is better at withstanding in water without causing any serious drawbacks. It is excellent in water resistance and thus, it is the best material to use for underwater or submerged constructing applications and building of pipelines, canals, etc.

There are certain drawbacks of using concrete as a construction material, like:

Low-tensile strength:
The tensile strength of concrete is very low, which is 1/10th of its compression strength. Several materials like fibres and polymers are added to the concrete to increase the tensile strength.

Lesser toughness:
Concrete has less ability to consume impact energy, which is how the toughness of a substance is considered. When compared to steel, it has been reported that concrete has only 2% toughness of that of steel.
