Concrete is one of the most important parts of any construction project and its quality will have a great impact on the overall structure of the structure. To ensure the quality of concrete, tests are done before and after concreting. Sanding operation is done after concreting in specific parts, the main purpose of which is to sample the desired concrete.
What is a concrete deafness?
Concrete scraping or taking the core from all types of concrete refers to a method in which pieces of concrete are separated from the surface of the concrete using special tools such as scrapers and are taken to the laboratory for examination and testing. This work is used to check the mechanical, chemical and physical properties of concrete as well as evaluate the quality of concrete. This work is done using special equipment and tools and requires technical expertise and knowledge of laboratory standards and methods.
What is the purpose of concrete chopping?
As mentioned above, concrete curing can be done for different purposes. In general, taking cores and samples from concrete in order to carry out more investigations and tests is one of the main goals pursued by Kergiri. Determining the compressive, bending and tensile strength of concrete, checking the density of reinforcements in foundations, beams, slabs and columns is carried out. In addition to taking concrete samples, sandblasting may be used for other operational purposes. For example, it may be necessary to drill holes in concrete to install power lines, telephones, pipes, and other equipment, in which case the best option would be to use the drilling method. Installing all kinds of holders and connections for the implementation of lighting equipment and other things is one of the other applications of this method.
How is concrete deafness done?
Taking core or drilling concrete requires very powerful equipment. In this process, a grinding machine is used. This device is used in different sizes depending on its type and power. Some are small and are carried by hand, and some are large, and many mechanical forces must be used to operate them.
In any case, these devices use electric, gasoline, and hydraulic forces to perform their tasks. They take. In the first step of the concrete grinding process, based on the calculations that have been made, they determine the exact place of taking the core or piercing the concrete. Depending on whether the purpose of drilling is to take a sample for testing or simply to drill holes in concrete, drills of different power and size are used. In the next step, depending on whether the surface is horizontal or vertical To get the core, several holes are made in the wall or floor using regular drills. These holes are used to secure the bases of the Kargir device. Some sanding machines have bases that are fixed to the bottom surface without the need for screws. After making sure that the bases are secured, the main engine of the device is placed on the bases.
In the last step, the device is connected to the energy source, which is mainly electricity. Water is one of the main resources needed for cleaning. Water plays several roles in digestion. On the other hand, it cools the drill. Cleans the drill path by moving cuttings upwards.
Upon reaching the desired depth, the device is turned off and the core is taken out. If the drilling depth is greater than the thickness of the desired surface, then the core will come out with the drill, but if the depth is less than the thickness, they use special tools to take out the core.
Cracker
Implementation of concrete sanding operations on any concrete surface must follow specific conditions and standards. In non-reinforced concretes, based on calculations, they determine the place of cracking, but in reinforced concretes, the case will be slightly different. In reinforced concrete, in order to avoid damage to the rebars, it is possible to determine their exact location inside the concrete using special scanners before starting work, and then based on that, determine the place of grinding. Sandblasting on reinforced and non-reinforced concrete has different tools and methods due to their different nature. In grinding on non-reinforced concrete, end and flat grinding machines can be used. In this case, unreinforced concrete, which is usually used in parts of buildings with different applications, is cut using a cutting machine and samples are taken for examination and testing in the laboratory. However, in reinforcing concrete, the location of rebars and rebars must be identified first, so that they can be ignored during the rebar, and this is important to maintain safety and prevent damage to reinforcements. Diamond and tube sanders can be used for sanding on reinforced concrete. In this case, the cutting machine cuts the concrete using a diamond blade or pipe, and samples of the concrete and reinforcements are taken for examination and testing in the laboratory.
