The current construction market is more vibrant than ever with unburnt construction materials, especially after Decree 139/2017/ND-CP encouraged and even required the use of this material in projects. Among them, aggregate concrete bricks, autoclaved aerated concrete bricks, and foam concrete bricks are popular choices, each with its own advantages and disadvantages.
Below are the differences between these three materials and why THT International's V-Lite foam concrete tiles are becoming the top choice in modern construction.
1. Aggregate Concrete Bricks (Block Bricks)
Main ingredients: Cement, grit, water and additives.
Production process: Bricks are shaped using steel molds through the process of hydraulic vibration or static pressing, then cured to achieve the desired hardness.
Advantage:
- High durability, good bearing capacity.
- Simple production process, low cost.
Disadvantages:
- Heavy weight, not suitable for high-rise buildings.
- Poor waterproofing, easily causing cracks and water seepage in the construction.
- No heat or sound insulation.
Due to these disadvantages, aggregate concrete bricks are gradually losing their position in the market.
2. Autoclaved Aerated Concrete Bricks (AAC Bricks)
Main ingredients: Cement, finely ground sand, lime, water and aluminum powder – gas generator.
Production process: The mixture of ingredients is mixed well and poured into the mold to shape. Then, the bricks are cut into blocks and put into an autoclave with high pressure and temperature to achieve hardness.
Advantage:
- Lightweight, easy to construct, reduces load on the project.
- Heat and sound insulation are better than aggregate bricks.
Disadvantages:
- Easy to absorb water, poor shrinkage and expansion, easily causing wall cracks after construction.
3. Foam Concrete Bricks (V-Lite Bricks)
Main ingredients: Cement, fly ash, synthetic fibers, foaming agents and additives.
Production process: The concrete mixture is mixed with foaming agent, creating evenly distributed tiny air holes. Thanks to its closed honeycomb structure, bricks have outstanding heat insulation and waterproofing properties.
Advantage:
- Uses 80% less mortar than traditional bricks, helping to save costs.
- Light weight, easy to transport and install.
- Good waterproofing, heat insulation, sound insulation and fire resistance.
- Overcoming the disadvantages of shrinkage and wall cracking, suitable for both high-rise and civil projects.
- High flexibility, can be used in many types of projects from partition walls, retaining walls to plant beds and garden landscapes.
Disadvantages:
- The initial cost is higher than aggregate bricks, but in return is long-term effectiveness and savings in maintenance costs.
