Flat slate is asbestos-cementplates, manufactured by special technology. This material has a wide enough scope. Most often it is used in industrial, housing and economic construction. The technical characteristics of flat slate are quite high. Among its positive qualities - strength, durability, fire safety, ease of installation. The material is produced in different sizes, which largely depends on its type and method of application.
Since the main component in the manufacture offlat slate is asbestos, then first it is worth talking about it. This raw material has been used in various branches of construction for over a hundred years, and with its help they make a wide variety of structures. Asbestos has a natural origin. It is characterized by extremely strong fibers that exceed the strength of even steel wire. Products from it combine excellent quality and low cost.
In the manufacture of flat slate using the following components:
The proportion of asbestos in this composition is 18%.When forming a sheet, its fibers are evenly distributed over the entire area. They adhere well to the cement mortar and form a reinforcing mesh. Thanks to this basis, flat slate, the sheet size of which is determined initially during molding, has an increased tensile strength, high toughness, fire resistance and other positive qualities.
Flat slate has a wider spectrum.methods of application, rather than its wavy fellow. It is quite often used in agriculture, industrial and residential construction. With this material, formwork for the foundation and “dry screeds” are made. During the construction they build walls according to the method of sandwich panels and balcony railings. Also flat slate, sheet sizes of which are different, suitable for arranging the roof, exterior and interior of buildings.
Quite often, slabs are used for erection.fences. In agriculture, they are built with sheds, gazebos, enclosures, pens and other economic structures. In the field of industry, flat slate has also been used. With it, fences are erected, technical mines are faced, floors are laid. Often, various small structures are mounted from this material, for example, trade stalls or pavilions.
Depending on the technology of manufacturing flatslate, it is divided into two types: pressed and non-pressed. These materials differ from each other in their technical characteristics. For example, slate flat pressed sheet size and weight is larger than non-pressed. Its strength is slightly higher, as is the cost. The cycle of freezing and thawing of this type of material is twice as large, and the error in linear dimensions is less. Tolerance for extruded slate - 4 mm, whereas for non-pressed - 8 mm.
Differences between different types of materialare also in the areas of their application. Slate flat non-pressed, the sheet size of which is slightly smaller, is used for cladding of buildings, installation of internal partitions, arrangement of insulated wall panels. Extruded material is used for the construction of household structures, installation of floor slabs, roofs, fences.
Each type of slate is indicated by a different marking, for example: LP-P-3,6x1,5x8 GOST. Letters in it are deciphered as follows:
Indicated in the marking numbers indicate:
Technical characteristics of slate flat inmost depend on the technological equipment used in the production, as well as the main part of the raw material - asbestos. In particular, the following factors affect the quality of the material:
The amount of asbestos in the composition and uniformityThe distribution in the cement of its fibers also affect the slate flat. Sheet size, specifications and other material properties depend on its type. More information can be found in the comparison table:
Characteristics | Pressed | Unpressed |
Density, g / cm3 | 1,8 | 1,6 |
Strength, MPa | 23 | 18 |
Residual strength,% | 90 | 40 |
Flexural strength, kgf / cm3 | 230 | 180 |
Cold hardiness, cycle | 50 | 25 |
Impact strength, kJ / m2 | 2,5 | 2 |
Шифер плоский, размеры листа которого бывают different, and the technical characteristics are quite high, widely used in various branches of construction. This is due to a set of positive qualities that distinguish this material from others like it:
Asbestos-cement products possess highstrength indicators. They calmly maintain the weight of a person. This quality is characterized as a wavy material, and slate is flat. Sheet size, wave and other modifications do not affect the strength.
Flat slate, in addition to numerous advantages, has some disadvantages.
Шифер плоский размер листа может иметь разный.All plates are rectangular in shape. Deviations from the geometric dimensions are possible, but not more than 5 mm. Weight depends on the size and type of material. Possible options are listed in the table:
Length, mm | Width, mm | Thickness mm | Weight, kg |
3600 | 1500 | 8-10 | 70-115 |
3000 | 1500 | 8-10 | 59-96 |
2500 | 1200 | 6-10 | 39-64 |
2000 | 1500 | 6-10 | 48-80 |
1750 | 1130 | 6-10 | |
1500 | 1000 | 6-10 |
Also, slate is often found to be flat, the sheet dimensions of which are: 1750x1130.1500x1000, 600x400 mm.
Flat slate is great stuffwidely used in construction. When choosing it, you should pay attention to the labeling in order to purchase a product whose qualities are ideally suited for you.
