With an increasing number of construction enthusiasts today, lightweight AAC blocks have become a widespread demand for construction, being durable, energy-efficient, and cost- effective. Among other block types, AAC Blocks have established themselves as an environment-friendly and high-performance substitute to traditional bricks. Let’s look at their strength, advantages of AAC Blocks and preferences for new construction.
What are AAC Blocks?
AAC Blocks are Autoclaved Aerated Concrete (AAC) AAC blocks, prepared from flyash, cement, lime, water, and a gas provider. Steam curing of these blocks is carried out with the autoclave process bringing their value up for strength and durability. Again, unlike ordinary clay bricks, lightweight AAC blocks are endowed with superior thermal insulation, which greatly decreases energy consumption in buildings.
Strength and Durability of AAC Blocks
High strength-to-weight ratio is one of the primary advantages offered by NCL AAC Blocks. These are lightweight yet highly durable: that is why these blocks are the very good material for load-defining and unsupported walls. With a compressive strength ranging between 3 and 4.5 N/mm², these blocks ensure good structural performance by reducing dead weight in the whole structure, a characteristic that makes it suitable for areas with seismic activity.
Lightweight AAC Blocks Have Advantages
Energy Efficiency: By minimizing heating and cooling costs, these thermally insulated blocks make a significant contribution to energy savings.
Eco-Friendly: These blocks are produced using fly ash, a waste product of the combustion of coal, thus contributing to sustainable construction.
Lightweight: Nearly 70% lighter than traditional bricks, it helps in easy transportation and handling.
Fire Resistance: They offer firefighting protection for up to 4 to 6 hours.
Pest and Mold Resistant: Their inorganic composition naturally disqualifies them from any infestations, as well as damage caused by moisture.
Faster Construction: Because of the standardised size, lightweightness and uniformity of AAC blocks, construction becomes fast and saves a lot of labour costs.
Frequently Asked Questions
Q. What is the strength of AAC blocks?
A. AAC blocks usually have a compressive strength around 3 – 4.5 N/mm², and they are designed to be strong enough to withstand various types of structures.
Q. What are lightweight AAC blocks?
A. These lightweight ACC blocks or gas concrete blocks are autoclaved aerated concrete blocks which are lightweight and specific for thermal insulation and fire resistance. All the new constructions nowadays are addicted to using these blocks as they are much more efficient and durable.
