Coring of concrete is called the operation of creating a hole or removing a part of concrete in a cylindrical shape. Kergiri is actually one of the different methods of cutting and coring from reinforced concrete or normal concrete.
Objectives of concrete curing
Creating concrete is done for various purposes. The most important of them are: creating a path for the passage of pipes, wiring, etc., as well as sampling of concrete for various tests that are performed in the concrete laboratory, in which various characteristics of concrete are determined.
In some projects, we need to perform a test on a part of the concrete, and this test cannot be done correctly at the location of the concrete structure. Therefore, a piece of concrete should be separated and taken to the concrete laboratory to test the concrete on it. It is in such a situation that it is necessary to remove a cylindrical piece of concrete by grinding concrete and deliver it to the laboratory so that it can be tested on it to obtain its various qualitative and quantitative characteristics. .
How to operate concrete grinding machines or drills
Special drills have been designed and built for this purpose, which are used in concrete polishing operations. The use of mechanical drills has a very long history in the construction industry and even goes back to ancient times. In any case, nowadays we use semi-automatic mechanical and electric drills for grinding concrete.
