How to perform core cutting in Reinforced Cement Concrete Structures
This construction video shows the detailed process on how to perform core cutting in reinforced cement concrete structures (beam/column slab). Before starting the process, compressive strength of the prevailing beam, column or concrete structure should be figured out.
Cores are generally cut with the use of a rotary cutting tool having diamond bits. In this way, a cylindrical specimen is acquired normally with its ends to be unequal, parallel and square and occasionally with embedded pieces of reinforcement.
Core cutting is performed for the following reasons :-
• To detect firmness and density of concrete
• To find out depth of carbonation of concrete
• Chemical analysis
• Water/gas conformity
• Petrographic analysis
• ASHTO Chloride permeability test
