In the construction of aerated bricks, it is impossible that there are no problems at all. So today's mini editor summarizes several common faults and solutions in the construction of aerated bricks. Let's take a look!
because Autoclaved aerated concrete blocks In China, the time for large-scale promotion and use is not long, and the production capacity of various places is not concerned. Because some projects are relatively tight, coupled with insufficient production supervision, the construction party's material supply is not up to standard, and the manufacturer's scale is small, the market has experienced a periodic shortage of local armour, which has led to a lot of unqualified blocks entering the construction site, such as many blocks still emitting hot gas when entering the T site. In this regard, we should strengthen the control of materials to ensure the ex factory age of the blocks. We should not use wall materials with an age of less than 28 years. We should ensure that the new wall materials have a relatively stable actual dry shrinkage value and high strength before use, so as to improve the tensile and shear strength of the wall. At the same time, we should also reduce the stress on the wall and reduce the dry shrinkage value of the product.
In practical application, we should pay attention to controlling the moisture content of the block and autoclaving Aerated concrete block The drying shrinkage rate of shall be ≤ 0.5mm/m, the compressive strength for external wall shall not be less than 5MPa, and the compressive strength for internal wall shall not be less than 3 5MPa。 In addition, the moisture content and depth of new wall materials shall be strictly controlled. When using, water shall be poured 1~2 days in advance, and masonry shall not be carried out while pouring. During construction in rainy season, wall materials shall not be stacked in the open air, reliable rain proof measures shall be taken, and wall materials wetted by rain shall not be built immediately
The above is about the common faults and solutions during the construction of aerated bricks. I hope today's explanation will help you!
