You ever thought. How many building materials have been invented over the past 20 years. Many classifications can be listed based on one or other signs. In this article I would like to consider asbestos -cement products. This group of materials is made of Portland cement, asbestos mixed in water. The role of the substrate is played by the fibers of asbestos, and the connecting substance – cement and water. Asbestos -cement is customary to be attributed to fine -handed cement breeds. The material under consideration shows good strength, fire resistance, durability and poor moisture absorption. Asbestos -cement products can be the following types: 1) Various plates designed for wall cladding 2) half -wave and wavy half alerted slabs. Field of activity – walls of walls. 3) the communications system (pipes, couplings) 4) roofing products 5) special -purpose products asbestos -cement products are different variations: pressed and unprofitable, painted or natural color. Today, only profiled slabs of large sizes are produced, and as for the roof production of plates, it is no longer relevant. Large items are simplified today as much as possible, which generally affects the cost of facing or roofing work. By the way, this also affects the quality of work in general. If you use the usual roofing, it cost about 30 percent more than asbestos -cement coating. Asbestos -cement products are used in many construction work: when lining walls, to organize roofs, as wall panels and ceilings. When creating a structure, it must be borne in mind that asbestos-cement sheets due to sharp fluctuations in temperature, they have the ability to increase. It is best to fix the upper part of the sheet, and the hole on the lower part of the sheet is made oblong, so that the nail does not interfere with the deformation of the sheet. There are standard dimensions of asbestos -cement plates – 1500×1200 mm, 1500×300 mm, while the thickness can be from 6 to 10 mm. Facing asbestos -cement products are used as a material for interior decoration of the room. Summing up, we can conclude that asbestos -cement products are very popular today, in addition, the quality of the products is at a very high level.
