Bricks are a kind of building materials that people use more frequently in buildings. After economic conditions become better, people's thinking is also active in updating with the development of the times. In the past, the brick walls of the earthen houses have been dismantled, and enough bricks have been purchased to prepare for rebuilding. There are many types of bricks, including red, cyan, and red for rural use, and blue for temples and other landmarks. Then let Xiaobian take everyone to look at the relevant content of the brick type .
The size of the ordinary brick is 240 mm × 115 mm × 53 mm. According to the compressive strength (Newton / square mm, N / mm 2), the MU30, MU25, MU20, MU15, MU10, MU7.5 are divided into six intensity levels. . Clay bricks are made in situ, cheap, durable, and have the advantages of fire prevention, heat insulation, sound insulation, moisture absorption, etc., and are widely used in civil engineering construction.
Waste bricks can also be used as aggregates for concrete. In order to improve the shortcomings of ordinary clay bricks, self-important, and more soil consumption, it is developing in the direction of light weight, high strength, hollow and large blocks.
The lime sand brick is formed by grinding and mixing with lime, quartz sand, sand or fine sandstone in an appropriate proportion, by adding water, mixing with water, semi-dry pressing and steam curing. Fly ash brick is made of fly ash as the main raw material, mixed with coal gangue powder or clay and other cementing materials. After being compounded, shaped, dried and calcined, it can make full use of industrial waste residue and save fuel.
Sintered shale brick
As a new type of building energy-saving wall material, sintered shale brick can be used not only for masonry load-bearing walls, but also has good thermal performance, which conforms to the construction building modulus, reduces the loss during construction, and reduces the working efficiency; Reaching more than 35% can reduce the weight of the wall and save the cost of basic engineering.
Compared with ordinary sintered perforated bricks, Jianling bricks are characterized by heat preservation, heat insulation, light weight, high strength and high efficiency of construction. The product uses shale as raw material, and adopts brick machine high vacuum extrusion molding and one-time burning production process.
Porous ceramsite concrete permeable brick
Porous ceramsite concrete permeable brick production method, which is to modify the sand-free porous cement concrete by adding polymer and adding water-absorbing high-strength shale ceramsite, without affecting the compressive strength of concrete. Improve the elasticity of the cement paste and the bond between the cement paste and the aggregate, thereby improving the mechanical properties and durability of the porous concrete; and utilizing the strong water absorption of the shale ceramsite.
The precipitation of cement slurry during the production of permeable bricks is reduced, and the risk of clogging of the cement slurry which is deposited during the preparation of the porous concrete permeable bricks is reduced, thereby expanding the water application ratio range of the porous concrete pavement bricks and increasing the applicable performance. The porous ceramsite permeable brick produced by the method can be used for laying a heavy traffic load permeable pavement with a passing vehicle.
How about, I read the relevant introduction to the types of bricks above, and I have learned a lot about the types of bricks. I hope that you can learn more about home improvement knowledge through this article, and you will be able to create a more perfect home environment. Thank you for reading this article and your support and love for Xiaobian. If you want to get more information about home improvement, please continue to pay attention to the decoration home network.

LED street light has revolutionized outdoor lighting, offering numerous advantages over traditional lighting technologies. With their energy efficiency, long lifespan, and superior performance, LED street lights have become the preferred choice for illuminating roads, pathways, and public spaces. However, not all Outdoor Adjustable Street Light Fixture is created equal. There are various classifications and types of LED street lights available in the market, each designed to meet specific requirements and deliver optimal lighting solutions.One of the primary classifications of Outdoor LED Street Lights is based on their wattage or power consumption. LED street lights are available in a range of wattages, typically ranging from 20 watts to 400 watts or more. The wattage determines the brightness or lumen output of the Outdoor LED Street Light, and different wattages are suitable for different applications. Lower wattage LED street lights are often used for residential areas, pedestrian pathways, or small parking lots, while higher wattage lights are more suitable for major roads, highways, and large parking areas.
Another important classification of LED street lights is based on their optical design and light distribution patterns. LED street lights are available in various beam angles, including wide, medium, and narrow beams. The beam angle determines the spread and concentration of light, allowing lighting designers to choose the most appropriate option for specific applications. For example, a wider beam angle may be preferred for illuminating large open spaces, while a narrower beam angle may be more suitable for focusing light on specific areas or reducing light pollution.
