What is deburring:
Chipping is the process of creating grooves on the finished concrete surface, commonly done in cast-in-place structures after the casting of the slab is completed. This chipping is necessary to ensure a strong bond for the subsequent casting of the next layer of columns and walls.
To put it simply, the process involves roughening the concrete surface with a drill and then thoroughly washing it clean, primarily to enhance the bonding between the concrete and the material being poured.
Section 2: The Role of Grooving
The reason for chiseling is not only to roughen the surface, but primarily to remove the laitance from the concrete surface, ensuring a dense and firm bond at the junction of new and old concrete. To illustrate with an analogy of a bridge:
1. Piers with broken pile heads or "roughening" treatment are in place; this is to remove non-tight concrete, ensuring quality.
Roughening at the joint of the 2 columns is done to ensure a firm concrete bond, and it also serves to eliminate the seam.
The top surface of the 3-beam slab is roughened to ensure a strong bond with the laying layer, as the laying layer is relatively thin and not roughening it can easily lead to peeling.

Section 3: Application Scope:
Surface roughening treatment for concrete products, including sawcut joints in precast beams and rebated modeling, followed by roughening at joint openings and areas with different heights.
Enhanced adhesion through coating cleaning, specific applications can be inquired with customer service in advance.
