Autoclaved aerated concrete blocks Masonry is generally used for infilled walls, and the strength grade of the blocks used is generally A3.5 for partition walls and A5 for exterior walls. Mortar strength shall not be less than M5.

autoclave Aerated concrete block Before masonry, block arrangement diagram shall be drawn according to the plan and elevation of the building. The number of bricks and the height of the bricks shall be drawn on the number of bricks and the height of the bricks, and the alignment line shall be drawn between the upper side lines of the relative bricks, and the bricks shall be built according to the alignment line.

Autoclaved aerated concrete blocks The masonry surface shall be watered appropriately. Special tools should be used for the masonry of aerated concrete (plastering shovel, saw, drill, router, straight frame, etc.).

Autoclaved aerated concrete blocks 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.

Autoclaved aerated concrete blocks The mortar joint of the wall shall be horizontal and vertical, and the mortar shall be full. The mortar fullness of the 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.

Autoclaved aerated concrete blocks At the corner of the wall, the blocks of the vertical and horizontal walls shall overlap 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.

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

1. Below the damp proof course of the building;

2. Long term immersion or chemical erosion environment;

3. Walls in the environment with vibration source for a long time;

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.
