Pencounton’s formwork is a constant or temporary system that is used to give concrete structures the desired shape. In order to fill the monolithic floor and walls correctly, frames, racks, boards, as well as fasteners, are used by frames, racks, racks, racks. In order for the walls and ceilings to be even, shields and decks should be smooth. Fastenies and forests ensure the stability of the structure. All work should be carried out comprehensively: along with pouring foam concrete and reinforcing.
Foam concrete is a fairly easy material, in any case, its mass is much lower than bricks or cement. Despite such his “lightness”, it is quite durable, durable and reliable. In addition, it can significantly reduce labor and material costs for creating the foundation.
It is also worth paying attention to preparation for work. It is necessary to clean the place of work from garbage, dust, other items that may interfere with the execution of wall pouring foam concrete.
Materials for creating formwork

For how many years now, in order to create this “fence”, shields of wood of various lengths and shapes are used, sizes that are chopped from uncircumcised or cut boards. Carrying and connecting parts are made from the beam. And in order to fix it, the masters usually take the bears made of wood, twisted wire twisted.
In addition, instead of wood, you can use plywood or metal sheets, which are most often installed when a non -removable formwork for foam concrete is needed. If you have chosen a tree in the role of a fence, take boards, the thickness of which should not be 20 mm.

Regardless of what foam concrete will be, its filling must be carried out in advance in the already prepared formwork. Its internal surfaces, which will be in contact with the solution, should be smooth and even, and the distance between the walls – fully corresponds to the width and height of the walls. It is best to shoot down a fence from the boards driven to each other – there should not be a single gap.
Foam concrete requires more sealed formwork than when pouring ordinary concrete. You must comply with this condition, otherwise, the mixture will simply lead out, which can cause many problems in the future.
When calculating vertical formwork, take into account the fact that the pressure of foam concrete increases by about 30% compared to conventional material, even if it will be the same density. But due to its lightness, the design of the future formwork can be easier. So, for example, for its manufacture you can use wood, aluminum, metal and even plastic. In order to reduce adhesion, you need to use lubricants from the emulsion. Their use will significantly improve the quality of the surface of the mixture, which will be addressed directly to the formwork.
Before laying the mixture, as we have already said, it is necessary to reinforce and collect the structure itself, which should be firmly fixed, especially in places where door and window openings, pipes, embedded elements and other details are located. Since the mobility of this solution is approximately 60 cm or higher, many worry that a stratification will occur or volume will be lost in the process, as is the case with ordinary material. However, this is not so – in foam concrete there are stable pores, which create the “effect of the ball”, so you can easily bypass the usual plasticizer. And thanks to its tractism, the mixture can easily fill all the forming voids during operation.
The filling process can be carried out either directly into the formwork, or with the help of a receiving funnel.

The mixture for filling should be at the same time plastic, but not very liquid, otherwise, the walls of your house may not turn out at all durable. Tromy solution, pay special attention to all places of contact of the mixture with the walls of the formwork, otherwise the surface can be with “pores”, which also affects its stability.
It is imperative to give walls (and inter -story floors) to survive for at least two weeks – this will allow the mixture to harden as much as possible and become very strong, and only then you can remove the formwork, if necessary. It is also important that you do not forget to place the reinforcement between the shields before pouring the solution, since this will make the floors or walls even more durable and durable.
