What's wrong with building a wall?

When decorating and building walls at home, I gave the materials to the master, considering that the master could not accurately list the materials. Because if I buy these materials, it will be very troublesome, and secondly, the materials will not be used up, so it will be a headache to clean this piece. Of course, I also made it clear to the master before the construction that the new walls at home should be built with red bricks, not light bricks. After all, the red brick wall has a good load-bearing function, so you can hang something on the wall. Unexpectedly, when the master built the wall, he found that all the bricks he used were black-hearted red bricks, which looked very poor in quality. When I asked him to replace them, he said I was stupid.

Let's take a look at the wall tiles in my house first.

As can be seen from the picture, not only each red brick has several black spots on the side, but also the inside of the red brick is basically black. And our common red bricks are all red. I'm really worried about what will happen to this wall in the later stage with this black-hearted red brick. Although I regret giving the materials to the master now, I still hope that the master will replace the materials, because it is definitely not possible to build a wall with this red brick. However, the master just smiled and didn't mean to change. He also kept calling me stupid and thought I didn't understand the goods.

Later, the master explained: in fact, the so-called black-hearted red brick means that the more black places inside, the better. Many people want to buy this kind of red brick, but they can't. The reason why the inside of this red brick turns black is that coal gangue is added to the clay as the brick that burns inside, so there will be black centers after firing. In fact, the strength of this kind of brick is much better than that of ordinary red brick, and there will be a crisp sound when knocking, so you can only say that you don't know the goods. If you are not at ease, you can consult other experts.

Judging from the above situation, as the master said, the control of red bricks is strict now, so this kind of black-hearted red brick can be said to be missing one piece. Therefore, it is best to find this kind of black-hearted red brick when decorating and building walls. If you can't find it, you don't have to. Ordinary red bricks will do. One more thing, if the new wall is not prepared to hang heavy objects in the later stage, it can be built with light bricks, which can not only reduce the load of the floor, but also facilitate the construction.

Second, another wall material: lightweight brick.

Lightweight bricks, as the name implies, are definitely light in quality, but what about the practicality of lightweight bricks? Many people will say, what's the use of bricks so light? In fact, don't underestimate its light weight, but its hardness is higher than that of red brick.

The cost of lightweight brick is low, and the market price of this kind of brick is also very cheap, and the production cost is also low, because its materials are mullite and tabular corundum, and then a proper amount of additives and rare earth oxides are added and fired at high pressure.

Lightweight brick has strong fire resistance, sound insulation and is very economical. This kind of brick has strong fire resistance, sound insulation and good waterproof effect. In addition, the construction of lightweight brick is very convenient, because of its light weight, so it is very convenient.

In addition, lightweight brick also has the characteristics of heat insulation, sound absorption, sound insulation, relatively small shrinkage value, no water seepage, environmental protection, good seismic performance, durability, machinability and good fire resistance. Don't underestimate it, it has many performance characteristics. At present, there are relatively few manufacturers of this kind of brick. One is that technology is still in the hands of a few manufacturers, and a lot of technical support is needed to produce qualified products.

Lightweight bricks have many uses, such as the house where we live, and are widely used at present. Everyone knows that building a house is a frame, and the walls are filled with this kind of foam brick, which is more convenient for construction. In the past, it was not easy to construct with red bricks, but it was much more convenient to construct with foam bricks. In fact, many road bricks and flower bed bricks are foam bricks, and large blast furnaces are also commonly used.

Three. Precautions for wall building

1, before the wall construction, it is best to water and wet the bricks and blocks two days in advance, and never cast them on the spot. Car owners and friends must pay attention to this!

2. Once the mortar hardens, don't add water to stir, and don't waste too much. The consequence of using overnight mortar is that the wall is unreliable.

3. Generally speaking, adding plasticizer into cement mortar will greatly reduce the compressive strength of masonry. Because of the characteristics of cement, it is best not to add plasticizer, otherwise it is not conducive to the stability of the wall.

4, mortar to avoid the rain, the operation should be standardized as far as possible, don't exceed the standard to increase the amount of sand, which not only wastes materials, but also is not conducive to increasing the strength of the wall.

Finally, I would like to remind you that indoor wall-building is not agreed by the owners of every community, so it is recommended to consult the property before the wall-building renovation, and the wall can be built only after the property agrees. If you build a wall indoors, you must pay attention to the construction details and safety issues to ensure the safety and health of your family after moving in.
