Product Description

Lightweight Precast Hotsale Blocks Autoclaved Aerated Concrete Block For Prefab Houses

Product Description

AAC panels are joined using thin bed adhesive: a dry mixed product made from a blend of cement, graded aggregates, and performance additives. Joints should be 2 to 3mm thick and fully filled. AAC panels should be bedded in 10mm mortar at the base of the wall when constructed on a slab edge set-down.

AAC blocks can be laid with conventional thick-bed mortar (approximately 10mm), however the manufacturer’s approved option is a proprietary thin-bed mortar. With this method, the procedure of laying the blocks is more like gluing than conventional brickwork construction. This is why many traditionally trained bricklayers may need some time to adjust to this different method of working. In addition, bricklayers are used to lifting bricks with a single hand and AAC blocks often require 2-handed manipulation. Although this may appear a slower construction process than laying masonry units, an AAC block is equivalent to 5 or 6 standard bricks.

All masonry walls are required to have movement or expansion joints at specified intervals. For AAC construction, movement joints must be provided at 6m horizontal centres maximum (measured continuously around rigid corners). Refer to the manufacturer’s guidelines for further information.

Features

Energy efficiency: Due to its cellular structure, AAC offers thermal resistance that may help reduce heating and cooling loads in buildings.

Fire resistance: AAC exhibits good fire resistance; its mineral composition and porous structure can provide extended fire ratings under standard testing conditions.

Workability: AAC can be cut and shaped using standard tools, allowing for precise fitting and reducing material waste on construction sites.

Environmental profile: AAC generally has a lower embodied energy and environmental footprint compared to traditional concrete. In some contexts, it may contribute to achieving points in green building certification systems such as LEED.

Low density: The material is significantly lighter than conventional concrete, which can simplify manual handling, reduce transportation demands, and may lower structural loads in seismic design scenarios.

Construction efficiency: AAC blocks and panels are often available in larger dimensions than traditional masonry units, potentially reducing installation time and labour. However, the overall impact on construction schedules depends on site-specific logistics and integration with other systems.

Moisture regulation: The vapor-permeable nature of AAC allows for limited water vapor diffusion, which can help moderate indoor humidity and mitigate moisture accumulation or condensation-related issues.
