Product Types of concrete. Companies-producers of concrete products typically specializes in the production of materials for walls, made by vibrocompression; products for the tiling and improvement. The most popular of reinforced concrete products are rings of the well cap the well and foundation blocks. The remaining output is produced by vibration compacting concrete in special forms of followed by solidification. In this way, get different kinds of blocks (septal, wall and air), 3 types of paving slabs ("coil", "brick" and the slab for the tram tracks), 3 types of curbs ("Garden", "road" and "roller"). In addition vypuskaetsyatovarny concrete in a large assortment. Reinforced concrete products are extremely durable.
The fact that the steel used as reinforcement construction, and concrete have the same coefficient of thermal expansion. This makes concrete one of the most durable and reliable materials. The plant manufactures 8 types of foundation blocks of various sizes – from 300mm (width) h580mm (height) h1180mm (length) to 600mmh580mmh2380mm. Ring wells produced 11 species, an outer diameter from 840 to 2200mm and a height of from 290 to 890mm. These reinforced concrete products are used to access devices located below ground pipelines for various purposes. Chastokoltsa wells used for the construction of drains, and sometimes for the construction of pipes. Also products are used as casing device for ordinary wells, dug for water supply companies as well as the private sector. Ready-mixed concrete – is a concrete mixture, which is made with the strictest observance of the production technology and quality control of products.
As you know, the higher the grade of concrete, the greater the burden on compression it can withstand. Concrete marki100 used for device preparation surface for subsequent layer pouring mixed concrete has a higher grade. Mark 200 is used for the blind area, floors and screeds, M300 – for the production of slabs and foundations. Higher grade ready-mixed concrete – is M400, which is used in bridge construction, hydraulic structures, girders and piles. Ready-mixed concrete of higher grades, due to its narrow scope, the factory is not made. The enterprise produces 7 types of concrete, 4 of them – are the main brands (M100, M200, M300, M400), and 3 intermediate (M150, M250, M350). Concrete is delivered to the place of construction work in special concrete mixers mounted on truck. A peculiarity of these mixers is that they work while driving, and not stir until the end of the ready-mixed concrete by the end of trip becomes ready for use. In all cases, to improve product characteristics such as increased strength, ductility, resistance to low temperatures and so forth, the concrete is added to the plasticizer.
