Autoclaved aerated concrete blocks Avoid building on the floor or in the air. For the root of the wall that is often affected by dry and wet replacement, such as the toilet, terrace, external balcony, and the contact part between the air conditioner support plate and the masonry on the external wall, C20 plain concrete wall pads with the same width as the wall thickness and a height of no less than 0.2m should be poured; For other walls, autoclaved lime sand bricks should be used to build wall pads with a height of not less than 0.2m at the root Aerated concrete block It shall not be used in the following parts: the parts of the building below ± 0.000 (except for the indoor infilled wall of the open room); Parts that have been immersed in water for a long time or are often replaced with dry and wet parts; Environments subject to chemical corrosion, such as strong acid, strong alkali or high concentration of carbon dioxide; The masonry surface is often in a high temperature environment above 80 ℃.

There are many processes in the whole production process of the complete set of aerated brick equipment. How long does the aerated brick equipment need steam curing in production? The steam curing of billets is carried out in autoclaves. The suitability of this process and how long it takes to steam are the key points for all brick factories to consider. If not properly autoclaved, the air block will not achieve its original excellent effectiveness. Unused or with poor resistance and resistance, it can not be well insulated. Fire resistant gas products will be at the disadvantage of the mall. Now let's talk about how long the autoclave time of the gas billet should be better in the kettle, so as to help more merchants to steam out high-yield and high-quality gas blocks. It is necessary to say a few points about the aerated brick equipment: generally, the total time for autoclaving the gas block in the autoclave is about 10-12 hours. However, I will tell you how long it should be accurate.

  Shenyang gas filling block The manufacturer reminds you to avoid Aerator block When cracks occur, we should pay attention to the following aspects during construction design: when the wall length exceeds 5m, reinforced concrete structural columns should be set in the wall to reduce the deformation deflection of the upper beam. For walls over 7m, in addition to two structural columns, a 120mm high waist beam should be set between the two structural columns to effectively eliminate vertical cracks. Reinforced concrete columns are set at both ends of window openings in rooms 1-2 on both sides of east and west gable. Add 80-100mm thick C20 under the window opening, with 2 inside Ф 8 Reinforced concrete strip, 2 Ф 8 The reinforcement is connected with the frame column to reduce the cracking caused by stress convergence. At the junction of concrete and aerated block, and around the electrical pipeline and switch box, steel wire mesh shall be added and placed in the rough surface of the painting layer. The masonry mortar shall be made of materials similar to the elastic modulus and linear expansion coefficient of the block; The additive containing glass fiber in the plastering mortar increases the crack resistance of the plastering layer.
