Fired bricks are a common masonry material in the construction industry, and all buildings cannot do without the use of products. Due to their beautiful appearance, practicality, and high value, they have attracted a lot of attention because they can have very beautiful patterns and colors. When laying the ground, such fired bricks can not only be beautiful, but also add charm, and have the following advantages:
1. Compressive strength: Fired bricks are commonly used for flooring, plazas, and road paving, so compressive strength is crucial. If the compressive strength is not sufficient, it is easy to break. Moreover, during transportation and construction, it may also cause breakage and unnecessary losses.
2. Water absorption rate, as it is commonly used for flat paving, should also reach 8% to 10% to avoid water accumulation on the road surface. Drainage, the grooves between the bricks laid can already allow water to penetrate underground, and the key to water absorption is that there is no accumulated water on the brick surface after passing through the water.
3. Wear resistance, squares and road surfaces are designed for people to step on, and passing through vehicles is not impossible. If the wear resistance is not sufficient, it is easy for the surface layer of the fired bricks to have pits or particle like wear, which will not break, but the appearance will be affected.
4. Frost resistance is mainly tested in cold regions such as Northeast China and Inner Mongolia. During winter, the temperature is usually around -20 ℃. The principle of thermal expansion and contraction inevitably destroys the surface layer and brick strength of some fired bricks. The frost resistance of other regions can serve as a reference.
Fired bricks are gradually being widely adopted and applied in the urban construction of first, second, third, and fourth tier cities in China. Their rich color schemes, bright yet soft colors, such as orange red, orange yellow, beige, ivory, coffee, brick color, gray, etc., all come from the natural kiln firing process of production kilns. The naturally rich color schemes form a natural and harmonious ecological picture of red, orange, yellow, green, blue, and purple with the surrounding lawns and garden vegetation.
