The development of fired bricks has a history of more than two thousand years, and it is still a widely used wall material in public places such as villa areas, residential communities, parks, schools, etc. In order to meet various needs, there are many types classified, mainly including:
Fired bricks: Bricks made from clay, shale, coal gangue or fly ash as raw materials, formed and fired at high temperatures, used for building load-bearing and non load-bearing walls are collectively referred to as fired bricks.
According to different raw materials, it can be divided into sintered clay bricks, sintered fly ash bricks, sintered shale bricks, etc.
Sintered ordinary bricks for shale fired bricks with solid or porosity less than 25% are called sintered ordinary bricks.
The production and use of ordinary clay bricks have a history of over 3000 years in China. Currently, wall materials are used in construction projects. Although ordinary clay bricks have many shortcomings, due to their low price, simple process, mature design and construction technology, and people's inertia in use, ordinary clay bricks will still be one of the main wall materials, especially in rural areas, for a considerable period of time in the future.
Shale fired bricks are made from shale as raw material, which is formed by hard plastic vacuum extrusion and sintered at a constant high temperature using gas in a tunnel kiln. Shale fired brick is a new type of environmentally friendly building material that integrates decoration and load-bearing. It belongs to the third generation of fired bricks in Europe, with a single unit energy saving of 65%. It has the advantages of high strength, thermal insulation, sound insulation, low water absorption, and frost resistance.
Shale fired bricks, as a new type of environmentally friendly building flooring material, can be used in public places such as villa areas, residential communities, parks, schools, stations, docks, airports, hospitals, various squares, municipal streets, amusement parks, etc.
