How Do You Cut Thick Concrete?

Cuts in concrete are made for a variety of reasons in the building trades, including installing windows and doors, removing damaged portions, and modifying the design of a structure’s outline. Cutting through thick concrete, however, is not an easy job and calls for forethought, the proper equipment, and the observance of all necessary safety protocols. This tutorial will cover the necessary procedures for thick concrete cutting in a secure and effective manner.

Safety Measures

It is imperative to take all required precautions before beginning to cut through heavy concrete to ensure a safe and efficient concrete cutting job. The first is obvious: always use safety equipment like goggles, earplugs, mittens, and a respirator. To secure the concrete, use a sturdy workbench or table, and keep your work space clear of clutter. When using a concrete saw, safety first means not cutting too close to any potential hazards like live wires, gas lines, or water pipelines. Last but not least, always have a fire extinguisher and first aid equipment handy.

Choosing The Right Diamond Blade

The success of your concrete cutting project depends largely on choosing the right diamond blade for the job. Firstly, consider blade diameter and choose a blade that’s the right size for your concrete saw. Secondly, select a blade designed specifically for cutting concrete. Thirdly, choose a blade with the right level of hardness for your concrete’s density and strength. Finally, choose a blade with the right number and arrangement of segments for your job.

Preparing The Work Area

Before cutting thick concrete, it’s important to prepare the work area properly. Firstly, clear the area of any debris or obstructions. Secondly, mark the area where you’ll be cutting using chalk or a marker. This will help you stay on track and avoid cutting too far. Thirdly, make sure the workbench or table is stable and can support the weight of the concrete. Finally, measure the thickness of the concrete to determine how deep you need to cut.

Cutting Thick Concrete

Now that you’ve taken the necessary safety precautions, selected the right diamond blade, and prepared the work area, it’s time to start cutting thick concrete. Here are the steps to follow:

1). Set the depth of the blade: Before you start cutting, adjust the depth of the blade according to the thickness of the concrete you’re cutting. Make sure the blade doesn’t go deeper than necessary to avoid damaging the saw or injuring yourself.

2). Position the saw: Place the saw on the concrete and line up the blade with the chalk or marker line you made earlier. Make sure the saw is perpendicular to the concrete surface.

3). Start the saw: Hold the saw with both hands, and gently squeeze the trigger to start the blade. Allow the blade to reach full speed before beginning to cut.

4). Begin cutting: Slowly guide the saw along the chalk or marker line, making sure to keep the blade perpendicular to the concrete surface. Don’t force the saw or apply too much pressure, let the blade do the work.

5). Move the saw forward: As you cut, move the saw forward at a steady pace. Don’t rush, take your time and keep the blade perpendicular to the concrete surface.

6). Complete the cut: Once you’ve cut through the concrete, turn off the saw and allow the blade to come to a complete stop. Remove the concrete and repeat the process until you’ve cut through all the necessary sections.

How Long After Pouring Concrete Can You Start Framing?

When it comes to framing concrete, it is important that you consider several factors before carrying out the job. These factors include the time it takes for concrete to cure, the concrete’s cured strength, environmental temperature, the type of concrete mix, and much more. 

Therefore, it is important to consider these factors when it comes to determining how long a concrete slab will need to cure before it can begin supporting weight. 

If you want to learn more about framing, concrete cutting and how long after pouring concrete you can begin doing so, then feel free to explore this topic with us below. 

How Long Until Concrete Is Strong Enough For Framing

Poured concrete can take up to 28 days to fully cure. However, while it takes concrete four weeks or more to fully cure, you won’t have to wait this long to start framing or cutting concrete.

Generally, you can start framing on a poured concrete slab seven days after it is poured. Around this time period, the concrete slab will have reached 70% of its fully cured strength. This strength level is said to be adequate enough to support loads such as the framing for a house.

However, there are also expansion joints that need to be cut into the concrete within the first 6 to 18 hours, and shouldn’t be done more than 24 hours after pouring. Timing of this is very important. 

If cut too soon, the joints will basically be useless. If cut too late, cracks would most likely have already appeared and will defeat the purpose of the expansion joints. The concrete joints must be sawed as soon as the concrete can take the force of the sawing without dislodging or ravelling aggregate particles.

How Long After Pouring Concrete Can Start Framing

Further to the cutting of expansion joints, there are around four other factors to consider in determining how long a concrete slab needs to cure before it can support weight.

The first factor is the amount of water present in the mixture. Cement that has a high water-to-cement ratio will cure slower but can be stronger in the long-term. Meanwhile, the second factor is the ambient temperature, where high temperatures can cure faster but lead to less strength over time.

The third factor to consider is the type of mix used. There are actually rapid curing cement mixtures available you should consider. The last factor to consider is the size of the concrete slab, where larger and thicker slabs need more time to fully cure.

During the curing process, it is important to keep the cement moist so that it can cure correctly. Spraying it down several times each day in the first week helps prevent the cement from losing moisture too fast. This is a very critical step that helps prevent the concrete from becoming weak once it is fully cured. 

Why Is Curing Important?

There are a number of reasons why it is critical for concrete to cure. However, the underlying reason is that curing helps give concrete both long-term strength and durability.

Another important factor to consider is that you must maintain the right level of moisture in the concrete during the curing process. This can be ensured by ponding, spraying, or covering the concrete. If concrete loses moisture too fast, this can lead to cracks and loss of strength. 

Overall, concrete curing aims to retain moisture in the slab to strengthen the concrete; keep the concrete from cracking until it is strong enough to resist cracks; and improve strength, durability, water tightness, and wear resistance in the final concrete outcome. 

Of course, wet cement is not able to support any weight, so drying is necessary. Therefore, curing ensures that the concrete dries correctly.

How To Speed Up Curing Times

There are actually various steps you can take to speed up curing times. Time is very valuable when it comes to construction projects, so why not maximise this valuable resource?

Some ways you can speed up cure times are the following:

  • Reduce humidity in the air by enclosing the concrete surface and running an HVAC system. 
  • Use the right amount of water, as less water can speed up both curing and drying times. However, keep in mind that this can make the concrete weaker in the future.
  • Avoid applying a sealant to the surface. If it is applied while the concrete is curing, it can retain too much moisture and lead to longer dry times.
  • Make use of a rapid-cure additive. These are specially formulated to cut curing times down without weakening the concrete over time. 

The important thing to keep in mind is that you should not take out too much moisture from the concrete, as this can lead to structural defects in the future. 

Final Thoughts

When it comes to framing poured concrete, make sure that you consider the aforementioned factors above. This is important if you want to maintain the structural integrity of the concrete structure in the long run. It is vitally important to ensure the concrete is cured correctly.
