Before looking for the AAC block latest price and size we need to know more about the AAC blocks. “Autoclaved Aerated Concrete” (AAC) blocks are used for the construction of walls. This is a lightweight material. it is an environment-friendly building material that provides high thermal insulation and durability for your construction. AAC block is also called “C4X” or “Siporex”. Its thermal insulation properties prevent heat and keep your room temperature cool. AAC Blocks are 3 to 4 times lighter in weight than traditional red bricks. Thus, it helps to reduce the unwanted load of the building. At present time AAC Blocks are fastly replacing red bricks for construction. Due to its amazing features, it became more popular.
What is the material used in AAC Block?
AAC (C4X) blocks are made on heat and pressure in autoclave. To manufacture it is composed of quartz sand, calcined gypsum, lime cement, aluminum powder, and water. and it can be used as a construction material for interior and exterior structures.

Advantages of AAC block
In today’s world, every industry realises the importance of environmental conservation, and the construction sector is also improving by upgrading advanced technology. Including innovative and sustainable construction materials where possible. Here are some advantages of AAC block.
- Earthquake-Resistant: It is common that buildings are designed to handle the verticle load of the structure. and AAC blocks gain high-level strength during the manufacturing process. It gives durability to the structure.
- Thermal Insulation: Generally, aac blocks can resist heat compared to traditional red bricks and keep your rooms cool and it helps to cost reduction in air conditioning.
- Faster construction and work: The size of the c4x block is greater than regular red bricks, so it can be more efficient to complete the same work in half time. having fewer joints and consistency ensures the ease of laying and making the work faster.
- Lightweight: c4x blocks are lightweight than red bricks. Thus, it prevents dead load on the structure.
- Cost Effective: for the large construction AAC block can reduce the cost of construction because it is better in cost when compared to burnt red bricks.
- Durable: AAC blocks are absorbs only 10% of water of its weight and climate change cannot affect it.
Disadvantages Of AAC block
- Installation: The laying work should be done in proper way as directed. Always use specified adhesive to construct it. improper installation of aac block can lead to cracks in wall and it affect the final finish.
- Non-load bearing material: it is non load bearing material. it can use for wall partitions.
- Because of its price, buying small number of blocks can cost your more compared to large scale of construction.
FAQs of AAC block
There are various reasons, first one is the poor quality of the blocks. always buy ISI-marked material for better results. the second one is you cannot use it in the foundation because aac blocks cannot be designed for heavy loads.
