1. What is a sintered brick?
Let's look at the ingredients in the sintered brick first. Bricks made of clay, shale, coal gangue or fly ash for building load-bearing walls and non-load-bearing walls are called sintered bricks. According to different raw materials, it can be divided into sintered clay brick, sintered fly ash brick and sintered shale brick. The production and use of ordinary clay brick has a history of more than 3000 years in China. Nowadays, ordinary clay bricks are still the main wall materials used in construction projects. Although ordinary clay brick has many shortcomings, it will remain one of the main wall materials for a long time to come, especially in rural areas, because of its low price, simple technology, mature design and construction technology and people's inertia in use.
According to different firing methods, sintered clay bricks can be divided into internal combustion bricks and external combustion bricks. Internal combustion brick is made by mixing combustible industrial wastes such as cinder and fly ash into clay raw materials. When the brick is fired in a kiln to a certain temperature, the fuel in the brick burns and the porcelain forms a brick. Compared with external combustion brick, internal combustion brick saves a lot of coal, saves raw clay by 5%- 10%, improves the strength by about 20%, reduces the apparent density of brick and enhances the sound insulation performance. This is also a remarkable advantage of sintered brick.
Sintered ordinary bricks can be used for building maintenance structures, brick columns, arches, chimneys, kiln bodies, ditches and foundations, and there are many building objects that can be used. It can be used together with thermal insulation materials such as lightweight aggregate concrete, aerated concrete and rock wool to build a lightweight wall with bricks on both sides and lightweight materials in the middle. Appropriate steel bars or steel mesh can be set in the masonry instead of reinforced concrete columns and lintels to become reinforced masonry.
Second, what is the use of sintered bricks?
Because the sintered brick has a strong anti-corrosion effect, in some southern environments, if you encounter some special circumstances, such as acid rain, the sintered brick can also play a great anti-corrosion role. In contrast, ordinary mascots can't have such an effect, and will be eroded soon after a long time. Therefore, sintered brick attracts many people's attention because of its powerful function and more and more extensive use, so I believe that in the future life,
Sintered bricks are mainly used in leisure squares, municipal engineering, landscaping, beautiful roofs, garden balconies, shopping malls, supermarkets, schools, hospitals, car 4S shops and other public places with large traffic. There are good and bad sintered bricks sold in the market, all of which are extruded. This kind of brick is the real sintered brick. Its biggest feature is environmental protection, because most harmful substances are volatilized by high temperature sintering. Secondly, it has high strength and durability. In fact, sintered bricks are impervious, and the water absorption of good sintered bricks should be very low and should be controlled below 8%. The water permeability of sintered brick is through the gap between bricks.
Each kind of brick has its own value. Compared with other bricks, sintered bricks have the advantages of corrosion resistance, sound insulation and heat preservation. Moreover, the raw materials used in sintered brick itself are very simple, and the application scope of sintered brick is very wide, including schools, squares, gardens and some infrastructure. , can be said to be a very popular brick.
