Fire-burning slab is a granite surface that has been burned with liquefied gas and oxygen through a high-temperature flame. Due to the uneven expansion of the heat, some unevenness is formed like a litchi surface, which has an anti-slip effect. Granite fire slabs can be used on sidewalks, roads, indoor floors and walls. Fire surface is mainly used in municipal paving projects (such as sidewalks, squares, and construction areas). In order to prevent slipping, the machine-cut surface of the stone will be burned at high temperature to form a "rough and bold fire surface". The fire surface can also be used as exterior drywall dryer. hang.

Fire-roasted noodles have the following advantages over traditional machine-cut noodles:

1. Rough effect Bold and sophisticated, it is rich and modern when used in stone dry-hanging projects.

2. Used to pave the ground of municipal gardens, with good anti-slip effect, creating an artificial landscape with deep courtyards and Suzhou scenery, revealing the historical and cultural background.

3. There is no limit to the thickness of the board.

Due to the special formation conditions and firm structural characteristics of granite, it has the following unique properties:

(1) It has good decorative properties and can be used for public purposes. Venue and outdoor decoration.

(2) Excellent processing performance: sawing, cutting, polishing, drilling, engraving, etc. Its processing accuracy can reach below 0.5μm, and its luminosity can reach above 1600.

(3) Good wear resistance, 5-10 times higher than cast iron.

(4) The thermal expansion coefficient is small, not easy to deform, similar to indium steel, and is minimally affected by temperature.

Granite is an intrusive rock, formed by the intrusion of underground magma and then cooling and crystallization. Has visible crystal structure and texture. It is composed of feldspars (usually potassium feldspar and feldspar), quartz, mica (biotite or muscovite) and trace minerals such as zircon, magnetite, ilmenite and sphene. Granite is an acidic igneous rock (silica content greater than 65). Typically, granite is slightly white or gray, with a mottled appearance due to the presence of dark minerals, and the addition of potassium feldspar makes it red or flesh-colored. Granite is formed by the slow cooling and crystallization of magma and is buried deep below the earth's surface. When the cooling rate is abnormally slow, it forms a granite with a very rough texture, which is called crystalline granite.

Curb stones refer to strips of stone or concrete cast as boundary stones on the edge of the road. Curb stones are also called curb stones, curb stones, and curb stones. Curb stones are the boundaries on the road surface that distinguish roadways, sidewalks, green spaces, isolation belts and other parts of the road. They play a role in ensuring the safety of pedestrians and vehicles and ensuring the neatness of the road edges.

According to the different materials used, they are generally divided into two types: concrete curb stones and stone curb stones. According to the cross-sectional size of the curb stone, it can be divided into H-type curb stone, T-type curb stone, R-type curb stone, F-type curb stone, TF-type standing curb stone and P-type flat curb stone. According to the linear shape of curb stones, they are classified into curved curb stones and linear curb stones. Curved curb stones with fired slabs can be used in conjunction with straight curb stones. With the rapid changes in the urban landscape, beautifying urban space has become an urgent need. The emergence of new and scientific colored road bricks and anti-color tiles

has played a new chapter in beautifying urban living spaces, with its high strength, high texture, wear resistance, non-fading and smooth linearity. and other characteristics have become a main theme of today's urban space. The forms of curb stones include vertical, inclined and flat. Walking on curb stones is a simple and effective walking method to adjust the balance of the body's internal organs. It can not only increase fun, but also prevent and cure diseases, prolong life, and play a role in ensuring the safety of pedestrians and vehicles and ensuring the neatness of road edges. effect. This article introduces the construction technology of curb stones from the trenching, installation and curb stone backing reinforcement of the pavement base, and summarizes the quality requirements and precautions for curb stones, in order to ensure the construction quality and improve the aesthetics of the road.
