Autoclaved aerated concrete product itself is a new type of lightweight and porous building material, which has good sound insulation and heat insulation properties, as well as a new type of wall material without radiation and durability.

　　 Aerated concrete block The vertical mortar joints of the upper and lower masonry blocks of the wall shall be staggered, and the staggered length should be 300mm, not less than 150mm. If not, set 2 at the horizontal mortar joint Φ 6 or Φ 4 The length of reinforcement mesh, tie bar or reinforcement mesh shall not be less than 700mm.

The mortar joint of aerated concrete block wall shall be horizontal and vertical, and the mortar shall be full. The mortar fullness of horizontal mortar joint shall not be less than 90%; The mortar plumpness of vertical mortar joints shall not be less than 80%. The thickness of horizontal mortar joint and the width of vertical mortar joint shall not exceed 15mm.

At the corner of aerated concrete block wall, the blocks of vertical and horizontal walls shall be overlapped with each other, and the partition blocks shall be exposed to the end face. At the T-shaped junction of aerated concrete block wall, the horizontal wall block shall be exposed to the end face and centered on the vertical wall block.

The aerated concrete block wall shall not be used in the following parts without effective measures:

1. Below the indoor ground elevation of the building;

2. Parts that have been immersed in water for a long time or are often subject to alternating drying and wetting;

3. Environment eroded by chemical environment (such as strong acid and alkali) or high concentration carbon dioxide;

4. The block surface is often in a high temperature environment above 80 ℃. Scaffold holes shall not be left on aerated concrete block walls. The block walls in each floor shall be built continuously without any joints. If it is necessary to leave a tenon, it should be left as a diagonal tenon, or it should be interrupted at the side of the door and window openings.
