What does concrete chiseling do ?
The main reason for chiseling is to chisel away the floating slurry on the surface of concrete, so that the old and new joint of concrete is dense and firmly bonded.
Take the bridge analogy.
1, the bridge has a pile foundation broken pile head, can also be seen as hair chiseling, the purpose is to use the redi lock rotary bush hammer plate to chisel away the uncompact concrete to ensure quality.
2, piers and columns combined with hair chiseling, the purpose is to combine the concrete firmly, can also play a role in eliminating the joints.
3, the top surface of the beam slab chisel, the purpose is to combine with the paving layer firmly, because the paving layer thickness is thin, not chisel hair easy to cause peeling phenomenon.

1, Bush hammer roller for grinding floor can remove the soft part of concrete (floating pulp).
2, Increase the surface area of the poured concrete section, so that the two poured concrete can be better combined
03
It is to groove, gutter and cut the pit of the original concrete pouring surface, so that the old and new concrete become a whole and the stubble is firmly connected.
04
The surface of the original concrete is cleared of floating slurry and impurities with a 20S planetary type bush hammer roller, so that the original concrete rubble is exposed to enhance the adhesion of the old and new concrete, improve the overall stability, increase the roughness of the concrete surface, increase the bonding area between the concrete and the original concrete surface, and increase the friction.
