The thermal insulation effect of 20 cm thick aerated concrete wall is equivalent to that of 49 cm thick clay brick wall, and its thermal insulation performance is far better than that of 24 cm brick wall. In this way, the thickness of the wall is greatly reduced, the effective use area of the building is correspondingly expanded, the thickness of building materials is saved, the construction efficiency is improved, the project cost is reduced, and the self-weight of the building is reduced. Aerated concrete has light bulk density, good overall performance, small inertia force during earthquake and certain seismic capacity. This is of great benefit to our earthquake-prone country.
Most partition walls are made of lightweight aerated concrete blocks. Masonry mortar generally adopts special adhesive, and the mortar joint with adhesive is about 4 mm, but the specification requires that the wall masonry needs to set reinforced Rachel bars with a length interval of not more than 500 and a diameter of 6, so it needs to be close to the groove on the aerated concrete block and put Rachel bars in the groove.
Extended data:
Aerated concrete block wall without effective measures shall not be applied to the following parts:
1. Below the moistureproof layer of the building;
2. Long-term immersion or chemical erosion of the environment;
3. Walls with vibration sources for a long time;
4, block surface is often in a high temperature environment above 80℃. Scaffolding holes shall not be left on the aerated concrete block wall. Each layer of block wall should be built continuously without any rubbing. If you need to leave a gap, you should keep it as an oblique gap or interrupt it at one side of the door and window opening.
