Disadvantages of CLC Blocks: Know Before the Home construction Disadvantages of CLC Blocks

CLC and AAC blocks are used for the construction of buildings. While both are popularly used, there are equal benefits and disadvantages of both the concrete blocks.
Before reading the disadvantages of CLC blocks, let us find out what a CLC block is and an AAC block.

Disadvantages of CLC Blocks

What is a CLC Block?

The full form of CLC block stands for Cellular Lightweight Concrete, also known as Foam Concrete. 

CLC block is a homogenous mixture of :

  • Fly ash
  • Sand
  • Water
  • Foaming agent (could be protein or synthetic-based)

Note that the properties of all these elements will decide the properties of cellular lightweight concretes; its properties are such as,

  • Strength
  • Thermal conductivity
  • Durability

The mix for the CLC blocks is decided based on the required density of the block.


What is an AAC Block?

AAc blocks are perfect for urban areas with high rise buildings with varied temperatures. The benefits of using an AAC block for structures are such,

  • High thermal insulation
  • Precision
  • Seismic resistance
  • Low maintenance

The full form for AAC stands for Autoclaved Aerated Concrete; its properties are as follows:

  • Light-weighted
  • Thermal insulation
  • Durable
  • Fire resistance
  • Pest resistant 

Rectangular AAC Block

How to Calculate AAC Block Size?

The AAC block size is generally calculated as 600 mm x 200 mm x 100 mm.

Below is a Table Showing you the Advantages and Disadvantages of CLC Blocks,

Advantages of CLC blocks Disadvantages of CLC blocks
It has lesser density, thus making it light in weight. Comparing it to AAC blocks, CLC blocks have lesser strength for the same density.
The material turns cool in summers and warm in winters, a great way to save more electricity. Its size and strength depend upon the plant’s curing and batching conditions.
It is an eco-friendly product as industrial leftovers and ashes are used to make it. Difficult to increase the production of CLC blocks.
The requirement of steel reduces, leading to more savings. Individual CLC blocks are costly.
Not much plaster is required to cover it. Heavy corner breakages
They are easy to install and requires minimal maintenance Inconsistent quality.
Reduced cracks in the walls as they have a lower water absorption capacity Has lower strength capacity.

Now that you have found all the advantages and disadvantages of CLC blocks. It will be very easy for you to choose the right ones for your home construction. There are certain drawbacks of AAC blocks too. It has a slower drying time, which means the flooring will remain wet for a longer time. While constructing a large model like a home or commercial space, quick-drying of elements is necessary.

Bottom Line:

I hope this article has all the information about CLC blocks, their uses, advantages, disadvantages, and significant answers about CLC and AAC blocks. After reviewing and in-depth study, we have concluded that usage of CLC blocks has many benefits, and you must opt for it. Keep reading to know everything you need to know about homesites, constructions, and general information about construction and buildings.
