Coal gangue porous bricks are not commonly used in home decoration. These bricks have a unique appearance, with many small holes distributed evenly, typically shaped as right-angled hexagons. In this article, we will explore what coal gangue porous bricks are and provide detailed information about their specifications.
What is a coal gangue porous brick?
A coal gangue perforated brick is manufactured using materials such as clay, shale, coal gangue, or fly ash as the main components. After being fired at high temperatures, these bricks have a porosity of at least 25%, with each hole having a diameter no larger than 22mm. The small and numerous holes give them a porous structure, which makes them suitable for load-bearing walls, hence the name "porous brick."
Specifications of coal gangue porous bricks:
In modern construction, replacing traditional building bricks with coal gangue porous bricks can reduce the overall weight of a building by approximately 30%. This material also helps save around 20% to 30% of clay usage, while the fuel consumption remains almost the same. It also reduces energy use by 10% to 20%, significantly improving the efficiency of wall construction and enhancing the thermal insulation and heat transfer performance of the walls.
These bricks come in two types: solid and hollow, which leads to different size specifications. The smallest standard size is around 90mm, while the largest can reach up to 290mm. The distribution of the holes is regular and uniform, ensuring a density of at least 25%. Commonly used dimensions today include 190mm x 190mm x 90mm and 240mm x 115mm x 90mm, which are widely used due to their practicality and efficiency.
Due to the presence of coal gangue, these bricks are known as coal gangue porous bricks. Their lightweight nature, combined with good thermal properties, makes them a popular choice in certain construction applications.
Editor's summary: Understanding the specifications of coal gangue porous bricks is essential for those interested in sustainable and efficient building materials. For more details, feel free to explore further on this website.
