Drywall – universal building material.

A plasterboard sheet is a plate of hardened gypsum dough with fillers, glued with two layers of construction paper or cardboard, playing the role of reinforcing coating. The paper surface is an ideal basis for the vast majority of finishing materials, such as paint, tiles, wallpaper, plaster. Drywall is suitable for both finishing and construction work. With it, it is easy to align the walls, ceilings, update old coatings with minimal time and means. Drywall is easily processed and great for creating decorative elements of the interior with a complex surface, for example, figured partitions and arched openings. The following types of drywall sheets are presented on the market: GKL – ordinary drywall. Designed for use in rooms with low humidity (not higher than seventy percent). GKLV – moisture -resistant drywall. In its production, impregnated cardboard is used, and antifungal and hydrophobic additives are introduced into the core material. Such drywall is used for construction and finishing work in rooms with a high level of humidity in the presence of extract and covering the front side of the sheet with ceramic tiles, waterproof primer or waterproofing. The level of humidity should not be above eighty percent. GCL – fire -resistant drywall, similar to GKL. Gypsum dough in such a sheet includes special reinforcing fillers. Like GKL, it is used in rooms with medium and low humidity. GKLVO – moisture -resistant fire -resistant drywall, combining the properties of GKLV and GLLC. Such drywall is usually much more expensive than ordinary. Along with drywall in construction, a gypsum fiber is used. This material according to the production method is similar to drywall, but it does not have an external coating – the gypsum base is reinforced with pulp fibers throughout the volume. Gypsum fiber has high strength and fireproof, however, its processing requires great effort than drywall. Gypsum -fiber sheets are widely used for firewall cladding of wooden structures. Gypsum cardboard is a modern finishing and building material that has proven itself in works at various levels of complexity. But we must not forget about its significant drawbacks – limited moisture resistance, low resistance to shock loads, etc. p.

This object has such a fate that involuntarily allocates it among others in Kazakhstan. The bridge across the Ural River in the administrative center of the West Kazakhstan region began to be built in the “good old days”, that is, under the Soviet regime. Since the republic never had their own organizations specialized in this case, bridge builders from different Russian cities worked here here. Then there was a notorious “parade of sovereignty”, followed by an economic crisis. Although the construction of the bridge continued, however, the payment of the executed volumes was now constantly delayed, or even at all moved away for an indefinite period. For this reason, the bridge builders stopped working several times. However, the object in Uralsk is one of the most significant in Kazakhstan, and therefore did not forget about it: the press periodically woke up this topic. Increased attention is also explained by the fact that the bridge across the Urals does not just connect the two banks of the river, it makes up an important link on the shortest path from Central Asia to the European part of Russia. As a result, the story of the invitation of bridge builders from a neighboring state was repeated again and again, without a visible result. There is a rather funny moment in it. A couple of years ago, when the President of Kazakhstan Nursultan Nazarbayev arrived in Uralsk, the local authorities invited him to take part in the solemn open… bridge over the Urals. The head of state made sensory words and cut the red ribbon. But when the ceremony ended and the president left, the entrance to the bridge was closed. The fact is that every driver who would decide to update the shortest path from Central Asia to Russia could well have been on the other side, but at the bottom of the river. The object was not over. And the main difficulty was not so much in building a car transition through the Urals itself, but in the construction of multi -kilometer approaches to it through a constantly flooded floodplain. And work here still start and finish. And now in the republic they decided to return to the long -suffering object again. The Ministry of Transport and Communications of the Republic of Kazakhstan announced the competition for state procurement of works and services for the reconstruction of the bridge over the Ural River. The required delivery time within 2000. Potential suppliers who meet the qualification requirements stipulated in Article 10 of the Law of Kazakhstan “On public procurement” are allowed to the competition.
