Coal gangue porous bricks are not commonly used in home decoration. These bricks have a unique appearance with many small holes, typically shaped like a six-sided right angle. In this article, we will explore what coal gangue porous bricks are and discuss their specifications in detail.
What is a Coal Gangue Porous Brick?
A coal gangue perforated brick is made primarily from materials such as clay, shale, coal gangue, or fly ash. After being fired at high temperatures, these bricks have a porosity of at least 25%, with the diameter of each hole not exceeding 22mm. The small and numerous holes make them ideal for load-bearing walls, which is why they are referred to as porous bricks. Their design helps reduce the overall weight of the structure while maintaining strength and durability.
Specifications of Coal Gangue Porous Bricks
Using coal gangue porous bricks instead of traditional building materials can reduce the weight of a building by approximately 30%. Since they use raw coal gangue and clay, they help save around 20% to 30% of clay, and the fuel consumption remains almost the same. This results in a 10% to 20% reduction in energy costs. Additionally, construction efficiency improves by up to 40%, and the thermal insulation properties of walls are significantly enhanced. These bricks come in both solid and hollow forms, so their specifications vary accordingly. The smallest size is generally around 90mm, while the largest can be up to 290mm.
In this special type of coal gangue porous brick, the holes are evenly distributed and maintain a density of at least 25%. The inner diameter of the holes does not exceed 22mm, making them small and densely packed. This feature gives them the name "porous masonry." Due to the inclusion of coal gangue, they are known as coal gangue porous bricks. Commonly used sizes today include 190mm × 190mm × 90mm and 240mm × 115mm × 90mm, which are widely adopted in modern construction due to their practicality and cost-effectiveness.
