With the ongoing technological advancement, several evolutions took place in the construction industry. However, the quality of a structure is measured with the type of blocks used during construction. Meanwhile, various kinds of bricks/blocks have been introduced for strong and eco-friendly constructions. Consequently, AAC blocks and CLC blocks are new variants that came to the limelight, receiving high appreciation for their sturdiness and cost-effective quality. So, in this blog, let’s go through the differences between AAC blocks and CLC blocks.
Description
AAC blocks stand for Autoclaved Aerated Concrete. AAC blocks are manufactured by blending compounds like fly-ash, gypsum, lime, cement, aluminum powder, and water. It carries almost 50% to 60% of air voids. It is a lightweight, durable, and high-insulating building product. AAC blocks enhance the quality of a building, are eco-friendly, and further reduce construction costs. On the other hand, CLC blocks stand for Cellular Lightweight Concrete or Foam Concrete. They are lightweight concrete and manufactured by combining slurry of cement, fly-ash, and water; further mixed it with pre-formed stable foam; hence, CLC blocks are lightweight, eco-friendly, and easy to handle.
Difference between AAC blocks and CLC blocks
- Raw materials
The raw materials used in the manufacturing process of AAC blocks are Fly-ash, gypsum, lime, cement, aluminum powder, and water. In contrast, materials used to produce CLC blocks are slurry of cement fly-ash, water, and pre-formed stable foam. Fly-ash is the standard raw material used in both blocks.
- Scalability
It is pretty challenging to increase the production of CLC blocks by using the same settings because all the equipment includes small capacities. The production of CLC blocks increases when additional storage spacing and curing time are provided to the finished products. Whereas, by installing different molds and autoclaves, the manufacturers can further increase the productions of AAC blocks. Thus, with less investment, production will increase. Therefore, AAC blocks are an ideal choice for builders.
- Production Capacity
As compared with AAC blocks, the production capacity of CLC blocks is relatively low. Furthermore, the production of AAC blocks is large and can further increase according to the clients’ needs. Thus, AAC blocks are ideal for large constructions and profitable for both the builders and customers.
- Compressive Strength
AAC blocks have a compressive strength of an average (3.5-7) N/mm³, superior to most types of lightweight blocks. Moreover, it is 25 percent stronger than other products of the same density. On the other hand, CLC blocks have a compressive strength of 3N/mm2. Bending strength is 15 to 20% of compressive strength which is much lower than the AAC blocks. So, we can say that AAC blocks are superior to CLC blocks in terms of compressive strength.
- Quality of end product
AAC blocks are factory-made products manufactured with the latest technology, so the end product’s quality is consistent and good. On the other hand, the quality of the end product of CLC blocks depends on the foam used and the degree of quality control. Hence, we can say that AAC blocks are superior to CLC blocks in terms of quality.
Conclusion
The above description shows the difference between AAC blocks and CLC blocks. Moreover, these two types have similar properties such as fire resistance, acoustic resistance, energy savings, joining process, water absorption, etc. Both these blocks are new in the construction industry, and people are gradually getting used to them. Being consistent and efficient in nature, AAC blocks have an add-on advantage of higher compressive strength than CLC blocks.
