Autoclaved aerated concrete blocks It has good processing performance. Able to saw, plane, nail, mill and drill. And reinforcement can be added during manufacturing. It brings great convenience and flexibility to the construction.

When the temperature of aerated concrete is below 600 ℃, its compressive strength has slightly increased. When the temperature is about 600 ℃, its compressive strength is close to the compressive strength at room temperature, so the fire resistance of aerated concrete as a building material meets the national first class fire protection standard.

When light brick partition is used, the door opening, especially the bathroom door opening, is the most likely place to have problems. The water vapor in the toilet is heavy, and it is easy to generate ponding on the ground, resulting in sewage overflowing. Yiming Decoration Engineering Department suggests:

First, lay the foundation with small yellow bricks. Small yellow bricks are commonly 95 bricks and perforated bricks. They are fine and dense, can bear weight, and have good water blocking performance. Therefore, when using light bricks to partition walls, it is better to use two or three small yellow bricks as the base, make a good foundation, and then build light bricks on this basis.

Secondly, embed the door frame fixing block. We know that as long as there is a door opening, it is generally necessary to install the door. The door should be fixed on the door opening with expansion screws, and then fixed with foaming agent. However, the light brick is brittle, and the expansion screw is easy to skew or loosen. Therefore, it is recommended to embed yellow bricks or cement bricks as fixed blocks at the places where expansion screws should be installed on both sides of the door frame.

Then, the reinforced concrete beam shall be placed on the door opening. According to the relevant national regulations, if the door opening is more than or equal to 80 cm, reinforced concrete must be placed as the beam. For the sake of peace of mind, ordinary masters put two pine bars on the door opening. In fact, this is very dangerous, and it is easy to cause paint cracking. There are also some black hearted masters who just build light bricks without letting anything go.

Finally, use mesh and interface agent on both sides of the wall. We know that light brick walls are easy to crack when they are made of latex. Therefore, before painting, we should use a special grid for priming, and use a special interface agent to powder the walls on both sides to form a solid first crack prevention barrier. On this basis, during the construction of wall painting works, it is required to use caulking paste, old powder and glue in a certain proportion to mix and mix them directly onto the wall, and quickly paste the special anti crack grid cloth for paint while it is not dry, so as to do a good job in the second pass of anti crack paint.
