Depending on the tasks, pouring concrete mortar can be done in two ways. In the first case concrete in Ramensky district placed in formwork, in the second - directly into the ground. The last option is usually used when making screeds, garden paths, etc.. Laying in formwork is a more complex and responsible process. To perform this job you need knowledge and skills.
Preparation for installation
To make the foundation as reliable as possible, must, so that the concrete mixture is of high quality. When laying it, you should strictly adhere to existing technology, otherwise, after some time, defects may appear in the base. Before, how to start pouring, formwork and reinforcement must be thoroughly cleaned of all contaminants. The fittings should not show even small traces of corrosion..
The concrete solution must be delivered to the construction site before, when it starts to set, that is, a maximum of an hour after preparation. Typically, ready-mixed concrete is transported in concrete mixers., which avoids separation of the mixture. Unloading should be carried out as close as possible to the place of installation.
Laying the mortar
You should know - concrete with delivery laid in layers, horizontally located. Wherein, before starting to lay the next row, the previous one should be well compacted. When layer-by-layer laying of the solution, breaks are undesirable. You should try to lay the next row before, how the old one will grab. Otherwise, seams may appear in the structure, which can lead to a decrease in its strength.
If a break is unavoidable, Concrete work can only be continued after thorough cleaning of the surface. The solution can be supplied in different ways: gasoline pumps, conveyors, pipelines, etc. It is not advisable to drop it from a great height. Concrete placement consists of its distribution, leveling and compaction. The latter can be done manually or with vibrators.
Row thickness may vary, its optimal value is 15-30 mm. This parameter is due to several factors: mixture compaction option, shape and size of the part, subject to concreting. The consistency of the solution also matters.. Concrete prices in Ramenskoye directly depend on him. You have to try, so that the entire space inside the formwork, including corners, places around fittings, etc.. were filled with concrete mortar.
