What Is Core Drilling Concrete

In this article, thepassionatewriter.com will try to examine what is core drilling concrete.

Core drilling, which is a type of concrete drilling and cutting machine in the construction industry, is used in many areas today thanks to advanced technologies.

What Is Core Drilling Concrete?

This machine is the name given to cylindrical concrete drilling today. After answering the question of what is core drilling, it would be appropriate to give information about drilling concrete with core drilling. This machine is generally preferred for drilling and cutting areas that are difficult to drill and cut. Another feature of the device is that it can be used in areas such as concrete floors and marble by adjusting the pressure level.

We can inform you that the meaning of the word Karot comes from the English word Carrot, meaning carrot. The process and device got this name because the pieces taken in the first core wall drilling process for the wall test were carrot-shaped.

What Are The Usage Areas of Core Core?

While the usage areas of the core drilling machine, which is a concrete drilling machine, were previously limited to taking samples only, today they are quite wide. These areas include:

• Low strength of samples taken from fresh concrete at the time of pouring
• Conflict situation between concrete producer and control (building inspection)
• Inability to take samples from fresh concrete at the time of pouring
• Determining the adequacy of applications such as placing and curing in concrete
• Control of the structure after events such as earthquakes and fire
• Making decisions such as reinforcement and demolition
• Renovation work
• Door-window opening
• Cable and infrastructure laying works
• Opening an expense

The type of core drilling device preferred for all these is different. If it is desired to be easy to use, a wet core drilling machine is preferred.

What is a Wet Core Drilling Machine?

A wet core drilling machine is a concrete drilling device used to apply more pressure when cutting concrete and to drill the concrete more easily. The core drilling machine is powered by electricity and can be used manually or on a stand.

What is Hand Core Drilling?

For those wondering what hand core drilling is, it can be described as a device similar to a hand-operated drill that is not mounted on a tripod.

Advantages of Core Drilling?

Nowadays, speed and practicality are extremely important for construction or any sector. Therefore, when asked questions such as what is core drilling and what are its advantages, the first answer can be given to a practical concrete drilling device. The models of this device used by hand or fixed to the ground provide great convenience to the operator. The ability to work with the pressure system in wet or dry conditions allows the device to operate on hard ground with zero error.

• It helps to do successful work in a short time.
• It only creates a hole in the area to be drilled and does not cause cracks or fractures in other parts.
• When you want to take a concrete sample, it allows you to take only a small piece without damaging the concrete floor.
• It helps create accurate incisions and holes for the purpose.
• Since it has many different types and drill bits, it allows opening holes of different sizes according to need.

How To Make The Ideal Core Draw?

• Samples should be taken from the most suitable places.
• It should be taken in the ideal size.
• A sufficient number of samples must be taken for analysis.
• It should be taken from concrete older than 28 days.
• When taking samples, attention should be paid to the existing plumbing line.
• Damage to the structure should be minimal.

Coring From The Column

• It is scanned with a reinforcement detection device and it is determined that there is NO reinforcement.
• The torque should be taken from the middle region, which is the zero point.
• Only 1 core is taken from a column.
• If the edge of the column is less than 30 cm, it is not taken.
• It is not taken from the tightening area.
• It is taken 3 cm from the inside of the column edge due to the margin of the pass.
• Due to the sample being taken close to the edge, the concrete may explode and spill, and the cross-section of the column will be weakened.

Core Retrieval from Beam

• It is not preferred as much as possible.
• It is scanned with a reinforcement detection device to ensure that there is NO reinforcement as much as possible,
• The moment is taken from the zero point, that is, the support region.
• Only 1 core is taken from a beam.
• If the beam height is less than 30 cm, it is not taken.

Does Core Drilling Damage The Building?

ITU Disaster Management Institute published a statement regarding the news that taking a concrete core sample from the building damaged its strength. The explanation is as follows: Studies carried out within the scope of TBDY-2018, the current earthquake regulation in force, especially in determining the earthquake performance and earthquake resistance of reinforced concrete buildings, do not offer steps that will weaken the current condition of the buildings. Concrete core samples taken from vertical load-bearing elements such as columns and curtains do not damage the load-bearing element from which the sample was taken in terms of strength. Moreover, the gaps opened for the cores are immediately filled with high-strength special mortar material.

Factors Affecting Core Strength

The core;

• Diameter of
• its delicateness
• place taken
• humidity condition
• Age
• Cutting effect on intake.

Why is core drilling used to take samples from concrete?

Because the core drilling method ensures that only the desired piece is removed from the concrete. Apart from this, it does not cause any spillage or breakage around the piece taken. Additionally, the core drilling machine enables easy processing of durable concrete that is very difficult to break and drill. Another reason for this choice is that the machine is extremely easy to use by hand or stationary. It is frequently used in concrete testing because there are many types of the device and one can easily choose one suitable for the area to be worked on. The important thing is to know how to perform the process and to choose the right machine needed.
