What is core testing of concrete?

Core tests are generally performed to assess whether suspect concrete in a new structure complies with strength-based acceptance criteria or not. In addition, it is critically used to determine in-place concrete strengths in an existing structure for the evaluation of structural capacity.

How do you remove a hole in concrete core?

Core Removal Insert each wire on opposites sides of the core, twist the wires to hook under the core, and pull the core out of the hole. For large cores, two opposing holes may be drilled into the top of the core at an angle using a hammer drill. Insert a rod into each hole and lift the core from the ground.

What is the drilling process?

Drilling is a cutting process that uses a drill bit to cut a hole of circular cross-section in solid materials. The drill bit is usually a rotary cutting tool, often multi-point. … Instead, the hole is usually made by hammering a drill bit into the hole with quickly repeated short movements.

How deep can you core drill concrete?

1-footDepth. Most of your standard concrete core testing samples can be drilled with a 1-foot bit. If you need to drill a core deeper than that, you can utilize barrel bits, which are essentially bit extensions that allow you to drill deeper than the cutting bit itself.
