Today, I would like to introduce to you what is sintered ordinary bricks and the rigid requirements of the state for sintered ordinary bricks

what is sintered ordinary brick

1. The sintered ordinary brick used in our daily life is actually a brick with a hole rate of less than 15%, which is slightly different in the use of raw materials. It uses several materials such as clay and shale, which are burned through a series of processes, and is widely used

2. Among them, clay bricks, which are used to produce sintered ordinary bricks, come from the field. In order to produce sintered ordinary drill, many people will greatly damage rice fields, causing serious ecological impact. Moreover, sintered ordinary brick itself has the disadvantages of low construction efficiency, heavy weight, poor seismic resistance and so on, so it has been banned in most parts of our country

the country's hard requirements for sintered ordinary bricks

1. The sintered ordinary bricks produced need to meet the specifications set by the country. They must be rectangular hexahedrons, of which the length needs to reach 240mm, the width needs to reach 115mm, and the thickness needs to reach 53mm. And according to the different production technology, it is divided into excellent products, first-class products, and qualified products

2. When we build buildings in life, we will use sintered ordinary bricks as the wall material, which can bring good indoor insulation and heat insulation system, which is very practical

3. For sintered ordinary bricks, due to different production processes, they are divided into five different grades. In order to better distinguish them, they are listed in the table for your reference:

4. Sintered ordinary bricks cannot appear frost on the site. The so-called frost refers to the dissolution of soluble salts inside the bricks, which eventually leads to the falling off of the brick surface, which seriously affects the quality of the wall, And it is also very unsafe. According to the different grades of sintered ordinary bricks, the frost requirements are also different

5. Some sintered ordinary bricks contain a small amount of limestone. In the process of building the wall, the bricks cause the limestone to expand and burst after absorbing water, which will reduce the quality of the bricks and greatly reduce the strength of the wall, causing a great threat in future life

conclusion: after reading what is sintered ordinary bricks and the rigid requirements of the state for sintered ordinary bricks, you should now understand it. Sintered ordinary bricks are still widely used in small and medium-sized cities, but the selected bricks should meet the rigid requirements of the country, so as to ensure that the built wall is more solid and not easy to cause trouble
