What is a Soff cut saw?
Husqvarna Soff-Cut is a unique patented system for early entry concrete sawing. This technology enables concrete to be cut within the first one or two hours of finishing and before final set.
How deep should relief cuts be in concrete?
A good rule of thumb is to make your cut ¼ the thickness of your concrete. If ¼ of your slab’s thickness, doesn’t reach 1” make sure you still cut at least a 1” depth.
How do you keep dust down when cutting concrete?
Wet cutting and water suppression Wet cutting is essential as the name suggests, adding water into the mix to effectively reduce the amount of dust generated by up to 85% as opposed to cutting through dry concrete.
How do you cut a 4 inch concrete slab?
Use a standard circular saw, equipped with a corundum or diamond blade, for small tasks. For slabs, it’s best to cut through the top inch, then use a sledgehammer to break off the rest. The jagged edge left below the cutting line provides a good rough edge for the new concrete to bond to.
Why do we multiply 1.54 to dry concrete?
1.54 is a factor that helps us to convert the Wet Volume of Concrete into Dry Volume. So that we can calculate the number of materials in dry condition. 1.54 is nothing but a 54 percent increment of Wet volume of concrete along with Wet Volume.
Should you use water when cutting concrete?
You can use a dry-cutting blade with or without water, but a wet blade must always be used with water. Whenever you cut concrete, wear sight, hearing and respiratory protection, especially when dry-cutting.
Can you cut through rebar with a diamond blade?
While it is possible to cut through concrete with rebar using diamond blades and a concrete wet cutter, it is a job that is usually best left to the pros.
Is it OK if it rains after pouring concrete?
Rain falling on top of freshly laid concrete can damage the surface and compromise a level and floated finish. Even worse, if too much extra water works its way into the concrete mix, this can result in weak concrete overall.
Why is my concrete slab Chalky?
The chalking and dusting of the concrete is caused by a breakdown of the top surface area of the concrete. The surface of the concrete will erode easily under general traffic. This can produce a powdery, chalky appearance.
How soon can you cut concrete after pouring?
For most concrete work, cutting should take place within the first 6 to 18 hours and never beyond 24 hours. Smaller early-entry saws are available, which may allow cutting to begin within a few hours after placement.
Can I put a metal cutting blade on my miter saw?
Don’t put a low-speed metal blade on a high-speed miter saw in an attempt to convert your tool. Rather, look for a metal-cutting blade that matches the speed of your saw. That provides a safe, effective method of cutting metal on a miter saw or similar tool. The same goes for chop saws.
How deep should saw cuts be in concrete?
Cutting Depth When concrete saw cutting, aim to cut to a depth of one quarter to even one-third of the concrete slab thickness. When cutting concrete with a circular saw you don’t want to cut too shallow or else risk random cracking.
How far apart should concrete cuts be?
Cuts should be approx. 2-3 times the thickness of your slab in feet. For example, a 6” slab would have cuts 12′ – 18′ apart. This is strictly a guideline to work from.
Should you wet concrete while curing?
ANSWER: Keeping concrete moist helps the curing process. Concrete hardens as a result of a chemical reaction, called hydration, between cement and water, not because it dries. The hardening, or curing, continues as long as moisture remains in the concrete.
