What are the specifications of bricks?

Nowadays, with the development of society, the requirements for the use of materials are getting higher and higher. Compared with traditional building porcelain, lightweight bricks are becoming more and more popular. Lightweight brick is not only light as its name implies, but also porous and low in density, which can provide sound and heat insulation. It is a new generation of energy-saving and environmental protection products. In the past, traditional building porcelain could not meet the requirements of high load, high heat resistance and high earthquake resistance, but the experience on lightweight bricks was effortless. Today, Bian Xiao will introduce lightweight bricks to you. ?

Light brick

Lightweight brick generally refers to the brick used for ordinary indoor partition walls. This kind of masonry foam brick will not increase the gravity of the floor, because the porous sound insulation effect is also first-class. Coupled with some special chemical materials in the brick, its fire resistance is also very good. It is a new generation of multifunctional products, which can not only meet the decoration requirements, but also reduce the waste of resources.

Specification for lightweight bricks

(1) 600mm * 240mm *100mm

(2)600 mm * 240 mm * 120 mm

(3) 600mm * 240mm *150mm

(4) 600mm * 240mm * 200mm

In addition to the above four specifications, there are some light bricks as small as red bricks. General tooling, 600mm*240mm* 100mm/200mm is more common. Moreover, a square is just seven bricks, and the construction is also very convenient and fast. For home improvement, I suggest you use 600mm*240mm* 100mm, which is completely enough. You'd better save it if you can. The specific size of the lightweight brick to be used still needs to be carried out according to the actual situation.

Advantages of lightweight brick

First of all, lightweight bricks are very environmentally friendly in materials, and can be recycled for many times without causing environmental pollution. Secondly, because of its light weight, the manufacturing cost is greatly reduced, and the gravity of the project will not be exerted, resulting in the influence of gravity. But also has the advantages of thermal insulation. Because of the particularity of the material and its porosity, it has a very good sound insulation and absorption effect.

With the change of time, many materials will be deformed to varying degrees. However, the shrinkage value of lightweight brick is also lower than the average level, and it is also earthquake-resistant and has first-class machinability, so it is a material used in many industries. In addition, when light bricks are burned, they can also resist heat and burn well. In short, they have many advantages.

Analysis and preventive measures of cracks in light material wall

1, block material problems and preventive measures. In most construction projects, the non-load-bearing light blocks used in projects that use a large number of light brick materials are mainly made of expanded perlite or cinder, and their capacity is light, which is superior to red bricks when used as non-load-bearing walls (especially high-rise buildings). However, the lightweight of bulk density cannot be pursued unilaterally in construction, otherwise its material properties will be worse than that of red brick, such as low strength, high water absorption, large drying shrinkage and long alkali drying shrinkage time, and the block will continue to shrink after leaving the factory. Therefore, in order to prevent the wall from cracking and poisoning along the block itself or along the mortar joint, three principles should be adhered to: first, the material staff should be required to choose a reputable big manufacturer; The second is to require buyers to place orders with manufacturers in advance to ensure the production life of lightweight bricks; Third, manufacturers are required to produce in strict accordance with the design requirements, strict quality certification, and it is strictly forbidden to enter the construction site with shoddy blocks and inferior pots.

2. Design structural problems and preventive measures. In most construction projects, the main problem of non-load-bearing lightweight block wall design is that there are no comprehensive preventive measures and technical disclosure measures. Because in the actual construction, the following problems will occur: (1) The edges of doors and windows, openings and reserved openings are stress concentrated areas, and cracks will occur due to impact vibration if there are no effective measures to strengthen Rachel. (2) build by laying bricks or stones to fill the retaining structure. When the size of the wall does not conform to the specifications of the block, it is difficult to completely fill the block, resulting in too many pores at the joint between the beam and column of the masonry and the brick frame structure, which is easy to crack. (3) Opening holes in the wall and installing pipes will cause deformation and cracking of the wall. (4) The thickness of the wall is too small, and the strength of masonry mortar is too low, which will make the wall stiff and easy to crack. (5) For the walls that are easy to contact with water, such as kitchens and bathrooms, structural measures such as waterproof and drainage, water seepage and dripping are not considered, which makes the walls leak.

This paper introduces a popular product-lightweight brick. I'm sure you may not know some production techniques of lightweight bricks. Here, we will make some specific introductions to lightweight bricks according to the production technology. Lightweight brick is actually a compound chemical product, but its production cost is very low and the raw materials are very simple. Such as fly ash and stone powder, when the temperature reaches about 45℃. Because different industries need different lightweight bricks, the production methods of lightweight bricks will be slightly different. At present, the more common ones are fixed and mobile.
