What Is
Autoclaved
Aerated
Concrete?
AAC is an innovative building material made from cement, lime, sand, water, and aluminum powder.
It’s one-fifth the weight of concrete, stronger than masonry, and provides unmatched insulation, fire resistance, and speed of construction.
Fast construction: Up to 50% faster installation
Energy efficient: Superior insulation reduces energy bills
Fireproof & durable: 6+ hours of fire resistance at 1600°C
Sustainable: Recyclable, eco-friendly construction material
How Autoclaved Aerated Concrete Is Made
01 Mixing
Cement, lime, sand, water, and aluminum powder form a lightweight slurry.
02 Aeration
Chemical reaction creates millions of microscopic insulating air pockets.
03 Autoclaving
The material is steam-cured at high pressure for exceptional durability and accuracy.
04 Cutting
Blocks and panels are precisely cut for faster, error-free installation.
Features of Autoclaved Aerated Concrete
Reduce build time by up to 50%. AAC’s precise dimensions, lighter weight, and fewer joints simplify handling, cutting labour, and accelerating project completion.
AAC offers superior lifecycle energy performance. Its lightweight structure reduces production and transportation energy, creating tight building envelopes ideal for net-zero projects.
AAC adapts to any architectural design and is ideal for residential, commercial, and industrial structures. Easily integrates plumbing and electrical lines without complicated masonry adjustments.
Precision-engineered with tolerances within 0.5 mm, AAC blocks and panels ensure faster installations, minimal waste, and fewer structural issues.
AAC provides exceptional thermal performance — 10 times higher than concrete, 3 times higher than brick — maintaining comfortable indoor temperatures year-round and reducing utility costs. It also provides a good Thermal Mass storage for additional comfort.
AAC maintains its structural integrity indefinitely, resisting decay, rot, mould, pests, termites, weather extremes, and chemical pollutants. AAC buildings have significantly longer lifespans compared to wood-framed structures.
AAC significantly reduces noise transmission (up to 56 decibels), providing superior acoustic insulation and enhanced occupant comfort.
Shorter installation time and reduced labor requirements lower overall project costs. AAC is also easy to maintain using standard tools, further reducing expenses.
Non-combustible AAC withstands direct fire exposure for up to 6+ hours at 1600°C, enhancing safety and compliance with fire codes.
AAC blocks are wire-cut for precision, resulting in a smooth surface that supports superior finishing and airtight building envelopes.
AAC’s semi-permeability naturally regulates indoor humidity, prevents mold growth, and eliminates the need for vapor barriers in many designs.
AAC waste is fully recyclable, used for sculpting, decorative landscaping, cat litter, soil amendment, or reincorporated into new production, minimizing environmental impact.
AAC’s cementitious composition provides exceptional strength and resilience, making it highly suitable for seismic and high-stress applications. Due to good seismic resistance, AAC absorbes and dissipates energy during earthquakes, and maintaining structural integrity.
AAC blocks weigh about 80% less than traditional masonry and bricks, simplifying handling, reducing shipping costs, and allowing taller structures.
AAC naturally maintains stable indoor humidity, temperature, and acoustics, creating comfortable and healthier living environments free from mold and pests.
AAC production uses up to 80% fewer resources than conventional concrete. It incorporates recycled materials such as fly ash and slag, promoting sustainability.

Frequently Asked Questions
Modern autoclaved aerated concrete (AAC) is not yet widely used in Canada but is gaining traction due to its exceptional advantages in construction. Rocksolid is actively introducing AAC to the Canadian market, offering opportunities for builders to adopt this innovative building solution that is already popular internationally..
This is a paragraph where you can include any information you’d like. It’s an opportunity to tell a story about the company.
Autoclaved Aerated Concrete (AAC) is widely used for constructing residential, commercial, and industrial buildings due to its versatility and performance. It is ideal for load-bearing walls, partitions, roofs, and floor systems, as well as for acoustic and fire barriers. Additionally, AAC is utilized in landscaping, art installations, and furniture due to its lightweight and easy-to-shape properties.
Aerated concrete blocks have a significantly long lifespan, typically exceeding 70 years when installed and maintained properly. Their durability stems from resistance to fire, moisture, pests, and rot, ensuring consistent structural integrity over time. Proper construction practices and regular maintenance can further extend their lifespan.
Yes, AAC blocks are suitable for load-bearing applications, making them ideal for structural and non-structural walls. Their high compressive strength and lightweight properties allow them to support significant structural loads while reducing the overall weight of the building, enhancing both construction speed and safety.
AAC offers distinct advantages over traditional bricks, including significantly improved thermal insulation, faster construction times, and superior fire resistance. It also reduces overall project costs through easier installation and reduced labour needs. These benefits often make AAC a preferable choice for modern, sustainable building practices compared to traditional bricks.
