The durability of the building erected to be in direct proportion to the use of building materials. Applying these or other species can significantly extend its operational period, as well as provide heat protection and construction even the sound insulation. Every year there is a tendency to improve the quality of our products. This is directly related to scientific and technological progress, mankind has presented a modified equipment and synthetic additives, which often serve to reinforce the manufactured materials and products. Today, most residential buildings, shopping centers, industrial facilities and other buildings are constructed of reinforced concrete building materials. Their molding is a process in which a concrete mixture in conjunction with the appropriate fittings, insulation and other materials attached to the desired shape. When the mixture is compacted, then grasped and hardens, forming a product given properties and dimensions.
So produced plates, blocks panels, foundations and other elements. This process is composed of a series of consistently conducting operations manufacture of concrete products, which include cleaning, lubrication and reassembly of the form, laying and fixing of reinforcement, concrete and other materials, seal the concrete mixture, smoothing the surface of the product and, finally, the setting and curing the mixture to stripping strength. Molding products can be accomplished in a movable and unmovable forms. Each of them is used depending on necessity, on the location and conditions. Manufacturer in move the form occurs in the course of successive transporting them from one station to the second, then third. At every point to make certain manufacturing operations, such as cleaning, lubrication, packing reinforcement, concrete, etc. In this case, cars and people doing these activities, which are located downstream in the appropriate positions. Molding products in non forms when all the manufacturing operations consistently committed in one spot moving cars and people, called the poster production. Here, Peter Thiel expresses very clear opinions on the subject.
This technology is used mainly for landfill-built temporary type. Basically it is used in manufacture large or long products, which moving from a post on a post due to certain difficulties. Regardless of whether a monolithic reinforced concrete products, or team, it manufactures in the formwork or forms, the primary purpose of which is to give the product proper shape, size and surface. Good sound insulation of various buildings provides a foamed concrete. Produce it by mixing cement paste (or mortar) with a special foam stable structure. It is insulating with volume up to 600 kg/m3 and constructive – Reinforced wire with a volumetric weight of more than 600 kg/m3. For the production of insulation type used dough cooked in a Portland cement not less than 300, and for constructive – solution of a mixture of basic ingredients with crushed quartz sand in a ratio of 1:1 – 1:3. The resulting mixture is poured into shape blocks and slabs. Compressive strength of insulating foam is 4-15 kg/cm2. Constructive (reinforced) material has a compressive strength of 50-100 kg/cm2. He has considerable strength in bending, allow the use of slabs of it at the same time as the insulation and the supporting elements.
