The use of monolithic casting technology increases the speed of building construction, allows you to get almost any building configuration, the structure is very durable, energy efficiency is maximum – the heat transfer coefficient of concrete is low, due to this you can save on heating in winter and air conditioning in summer. The cost of construction is less compared to brick buildings by up to 30%. In addition, the cost of exterior and interior decoration is reduced, the problems associated with the supply of materials in dense urban areas and heavy traffic are minimal, and the strength of the building can withstand even earthquakes.
Using fixed formwork
Time does not stand still and new technologies come to replace the old methods. An example is such a thing as fixed formwork. Due to the ease of installation and the absence of the need for disassembly after pouring concrete, it is becoming more and more common. In addition to a serious reduction in the time spent on construction, its components, while remaining a structural element of the building, improve its sound insulation and reduce thermal conductivity. There are several most widely used materials for its manufacture.
Expanded polystyrene is a very convenient and cheap fairly material for the manufacture of fixed formwork. They can be made in the form of a set of plates or special blocks with cavities inside. The latter are more convenient due to the fact that special grooves and protrusions are made on their ends to ensure the reliability of the connection.
The construction of a concrete building using blocks is carried out in the following sequence: a waterproofing layer is applied to the finished foundation, on which the blocks are installed, forming the first level of the structure. Then a reinforcing strapping is laid in the cavity and concrete is poured. The operation is repeated cyclically until the overlap level is reached.
This is a material in which the role of the base is played by crushed wood bound with cement. The use of such components significantly increases the environmental friendliness of the building and increases the practicality of installation. As a rule, fiberboard is made in the form of plates of various sizes.
The method of application of fibrolite is as follows. The finished strip or block foundation is waterproofed, and then fiberboard plates are installed on it in the required sequence. They are fastened together with special metal brackets. It is necessary to carefully fit them to each other in order to avoid leakage of concrete through the cracks. Then reinforcement is laid in the resulting voids and the concrete mixture is poured. The advantage of this method is the ability to perform various structural elements at the required angle relative to the ground level.
The difference between wood concrete and fiberboard is small. In both cases, the basis is wood filler bound with cement mortar. However, wood concrete is cheaper, since it uses waste products from the production of wood products, and not specially made chips. Due to the finer structure, the moisture absorption rates are very high, which contributes to the accelerated set of concrete of its branded qualities. The construction of structures using wood concrete slabs is in principle similar to the use of fiberboard. After the completion of pouring concrete and acquiring the necessary properties, external finishing is carried out in order to improve the exterior of the building, as well as to exclude the impact of external harmful influences on the formwork.
