Sesame Gray Granite Stone

Sesame Grey Granite Pavers is one of the most popular outdoor paving stones in the world at present. The background color of this stone is dark gray with a slightly bluish cast. There are countless tiny dot-like textures evenly distributed on the dark gray background. The shape of these veins is very similar to black sesame, which is also the origin of the name of this stone.

The material of this stone is relatively hard, and its strength is relatively high, which is not only suitable for the application of various outdoor scenes, but also ensures a relatively low breakage rate during processing and transportation. In addition, the slab surface of this stone is relatively stable, and the color change between different slabs is relatively small. Moreover, the texture style of the granite slab is uniform, which is a very good building material. In a variety of different scenarios, whether it is parks, sidewalks, roadways, parking lots or outdoor areas of squares and shopping malls, you can see the perfect application of this natural granite.

Different stone selection criteria are different. The application selection of sesame white and sesame gray mainly depends on the surrounding environment and the matching stone color. Sesame white and sesame gray are natural granites with many uses. They can be used for floor and wall decoration, special shapes, mosaics, landscape stones, carvings, stair steps, countertops and door stones, etc. Which one looks better, sesame white or sesame gray? Personally, I think sesame white is more atmospheric. If you consider the stain resistance of use, it is recommended to choose sesame gray for easy-to-dirty floors, such as floors that are often exposed to oil smoke and sewage. It is recommended to use sesame white for squares and commercial entrances or steps.

The main difference between sesame white and sesame gray stone is the color and physical indicators. In terms of the distribution of origin, sesame white and sesame gray stone are available in many places in China, including Fujian, Henan, Shandong, Shandong and other places. There are sesame white and sesame gray mining areas, but there are some differences in quality, color and texture. It is recommended to choose white hemp in Jining, Shandong, which is more cost-effective.

1. Sesame white is a deep-seated acidic igneous rock with a silica content of more than 70%. The material is mainly composed of dark minerals such as quartz, feldspar and a small amount of biotite. The dark minerals are mostly biotite, which contains a small amount of amphibole. In terms of the scope of use and domestic and foreign sales in recent years, the frequency of use of sesame white granite is much higher than that of sesame gray granite. In terms of price advantage, the price of large and small flowers in sesame white Pingyi (Jining, Shandong, Pingyi, Shandong) is lower.

2. The quartz content of sesame gray granite is 20%-40%, the density of the stone is high, and the Mohs hardness is about 2.5-2.7, which is much higher than marble. The composition of alkaline feldspar is less than plagioclase, accounting for more than half of the total amount of feldspar. Alkaline feldspar is various potassium feldspar and sodium feldspar. Plagioclase is mainly sodium feldspar or plagioclase. The color system of sesame gray is also divided into large and small flowers.

In the comparison of the two stones, it can also be distinguished from the main color. Sesame gray is a white granite stone. Sesame grey and sesame white can be easily distinguished from the color alone. Sesame grey is more depressed and dark, while sesame white is very bright. It can be likened to a cloudy day and a sunny day. The hardness of the two stones is basically different. In terms of selection, if you are not particular about details, you can also choose according to your own preferences. Generally, sesame white and sesame grey stones are mainly used for curbstones, dry hanging boards, road paving, and car blocks and pillars.

Most Sesame gray granite stone is used for exterior walls, so the safety of the exterior walls is very important. When installing Sesame gray granite stone curtain walls at a certain height, experienced construction workers understand the importance of thickness, because they need to consider the strong wind and the stability of the installation. In addition, there are differences between different materials, which need to be adjusted according to the actual situation. In addition, installation parts cannot be saved. Everything must be considered for quality and timeliness.

Strong wind force
The higher the floor, the more unstable factors there are. One obvious point is the wind force. People standing on it will feel it very clearly, not to mention the safety of construction. In actual conditions, when the Sesame gray granite stone curtain wall does not have a fixed thickness, the back bolts driven in are not stable enough, and the uncertainty increases while bearing the wind force. This problem must be taken seriously.

Different safety specifications
There are differences in safety specifications for different materials. If the Sesame gray granite stone curtain wall uses Sesame gray granite stone, the thickness specification must be more than 35 mm. If granite is used, the specification is more than 30 mm. As long as the standard is safe enough, there is no problem. However, after changing to other materials, workers must also choose materials according to the new standards.

Install enough back bolts
During the installation process, you must also pay attention to adding enough back bolts. You cannot ignore safety in order to save time. The usual practice in the industry is four. However, when the Sesame gray granite stone curtain wall is thick, the number is raised to six. In essence, the fewer the number of back bolts, the greater the pressure on the inside. It is recommended that on-site construction should be more rigorous and not limited.

The installation safety of Sesame gray granite stone requires the installers to pay attention to safety. After all, stone is a harder object and is more harmful to people. Adding too much will also cause other troubles, such as extended construction period and reduced efficiency, but go to the other end.
