The Basics About Concrete Coring

Whether you’re a beginner or an expert, there are a few things you need to know about concrete coring. You’ll learn how to drill through concrete, how to get a core out of a core drill bit, and how to test the strength of solid concrete in a tower.

Drilling through concrete

Using the right drill bit is key to drilling through concrete. This may seem like a no-brainer, but there are many drills on the market, so which one is best for your project?

A hammer drill is a great tool to use for drilling through concrete. Unlike a rotary drill, a hammer drill breaks the concrete and fractures it into small pieces. This makes drilling through concrete much easier.

For best results, you’ll want to use a hammer drill that is designed for this task. Also, make sure to have the proper anchors. A common practice is to use a rebar sleeve to protect the concrete from damage.

You can also drill through concrete with a rotary drill, but you’ll need a specialty drill bit to get the job done. For example, a diamond-tipped blade has a hard time cutting into steel.

A cordless drill can make drilling through concrete easier, but it can also be daunting. Cordless drills come in different sizes and price ranges, so you’ll need to consider your budget and needs before purchasing.

Getting a core out of a core drill bit

Getting a core out of a core drill bit can be a challenging task. There are many variables that can affect the coring job. The material being drilled, the type of material being drilled, and the age of the concrete are just some of the factors.

The core drill rig is made up of a base, telescoping armature, and a drill bit. These components are mounted on a sturdy frame that prevents seizing.

Once the drill bit is mounted and set, the core drill is turned on. Its telescoping armature is then tapped with a rubber mallet. This will release the wedge.

The core hole should be slightly smaller than the opposite side of the wall. If the hole is too large, the bit will not be able to cut the core cleanly. The core bit should be stopped 1/4 to 3/8 inch from the opposite side of the wall.

Once the core hole is stopped, the core drill wrench should be used to rotate the bit backward. This releases the wedge and allows the core to be removed.

Testing the strength of solid concrete in a tower

Using non-intrusive testing methods to assess the strength of solid concrete in a tower is a smart choice because it reduces the number of destructive tests and means shorter down-times. It also means saving money by avoiding the need to spend on costly testing services.

The compressive strength of concrete is measured using a special machine. It uses a rebound hammer to measure the reverberation of a spring-driven hammer mass when hit with concrete. Using an ultrasonic pulse velocity to measure the rebound of the spring-driven hammer mass can improve the accuracy of this test.

The most important property of concrete is its strength. This property is largely dependent on the duration and temperature of the curing process. Higher curing temperatures promote early strength gain in concrete.

Typically, the compressive strength of concrete is measured in pounds per square inch. However, the flexural strength of concrete is also a factor to consider. It is generally estimated to be 10 to 15 percent of the compressive strength.

Cutting a conduit run

Whether you need to cut a conduit run or you need to repair an old one, it’s important to learn the proper techniques for cutting concrete. An improperly cut hole can result in a safety hazard and unnecessary expenses for repair. You also need to know what types of cuts to make and how to choose a professional to do the job.

When you’re cutting a conduit run, you want a smooth, clean cut. You want a hole that’s free of cracks or subsurface voids, which can damage your concrete. You also want the sides of the hole to be smooth. This is to ensure that the core’s integrity is not compromised.

In order to cut a conduit run, you need a special cutting rig. The rig has a hollow shaft and a dedicated drill bit. The rig is usually electric and runs off a portable generator. The rig can weigh up to 150 pounds.

Once the rig is in place, workers must tap the bit with a rubber mallet to remove any bituminous binding agent. This agent melts with the core drilling heat.
