In order to enhance monolithic floors from reinforced concrete, it is necessary to lay an additional plate on top of the previously installed slab. Its thickness should be at least 5 centimeters. It is also necessary to reinforce a special grid. To ensure a more reliable adhesion of new concrete with the old one, you need to clean the slabs and apply notes. If this cannot be done due to the large pollution of the old ceiling, then the best option will be an additional increase in the thickness of the stove by another 5 centimeters.
In order to reinforce in the stretched zone of reinforced concrete beams, it is necessary to lay additional reinforcement in them. This is done by welding to previously cleaned reinforcement, which will hold back the enhanced beam. Welding is done with the help of keyworms, which are welded to the gaskets or to the rods of the reinforcement. To do this, you need to beat off the protective layer of concrete and make holes with a diameter of 10 cm, and the distance between them execute 30-50 cm. Then the rods are welded with a seam. The required seam length is 7-8 cm. In this case, the lower layer must be well concrete. This is done using fragmentation.
To do this, apply a layer of torque-concrete, which should be approximately 10-20 millimeters thick. If there is a need to make more the thickness of the intensified structure, then you need to do fragmentation in several layers. It is worth noting that each subsequent layer should be applied only after the previous one is completely dry.
If there was a break in construction, and a layer of torque-concrete has already been imposed, then when renewed work, it is recommended to rinse the surface.
With the onset of the mass of mass construction work, the demand for all building materials is raised. Interesting and profitable proposals for geomaterials are waiting for you on the STSGEO website, where each type of these materials is described in detail. You can choose and buy the necessary building material.
