As sawing aerated: the secrets and nuances. Part one.

Aerated concrete is considered one of the most popular building materials - largely due to the ease of processing. Aerated concrete blocks can be sawn, to equalize irregularities special planes, Stroebe by further laying of utilities.

Although there are many FORUMHOUSE article, which tells about the aircrete, From novice developers often raises the question of what and how to saw a concrete block. This is what we describe in our article.

The basic principles of working with gas concretes

To begin, we suggest to familiarize with the following table, which shows the results of a survey of users of our portal, "Who, what and how aerated concrete saws."

As the table shows, in the first place by a wide margin, there is a hand saw on aerated concrete. The remaining positions shared between mechanized assistants. This is not surprising, because the hand saw for aerated concrete - the cheapest and easiest way to cut the concrete block into two parts.

Despite the popularity of this method, there is no consensus, whether the cut aerated manually convenient among our users. Some builders say that this method is justified, even during the construction of a large house with a lot of work cut aerocrete. Others believe that we should not spend so much energy on manual work, if the process can be simplified and accelerated by using an electric tool.

I tried to saw "four hundred" gazoblok saw, carbide tipped on each tooth. Sawn initially good, but spent a lot of time and effort. Moreover, the web leads away, and the cut turns curve. Have to roll all the time block. I think to buy a saber saw.

vic_v (User FORUMHOUSE):

I used three hand saws. And branded with "pobeditom" on each tooth, and simple, where TCT go through the tooth. It's not something proprietary, of course, saws well, but "nouneymy" worse, but the main drawback - saw leads by 5-7 mm per side. Also pondered the mechanization process. I would like to buy a saw, alligator, that's just embarrassing price.

So, two people were in favor of working with gas concretes with a special power in return for a handsaw. Whether justified this purchase? To begin with let us recall what a reciprocating saw and what saw, alligator. Without going into technical details, let's say that the reciprocating saw, in fact, is a large and powerful jigsaw where the saw blade does not move vertically and horizontally, imitating the movement of a person, usually work saw.

In this case, the tool, unlike the alligator type blade has one cutting blade - nail file as a saber.

We saw an alligator-rotational movement of the motor is converted into a reciprocating motion. Thus saw blades (2 pcs.) Also moving horizontally but in the direction opposite to each other. Res are clean and neat.

Saws, alligators are more expensive than conventional saber, and their purchase is considered to be warranted at the professional building.

Dmitry Kale (FORUMHOUSE Consultant):

I believe that if the house does not have bay windows, difficult angles, and so on, that is - a simple form, you have to cut a little. In this case, you can do a handsaw, and to buy "alligator" does not make sense.

Before purchasing expensive power tools designed for narrowcasting or professional activity, need to think about where you will be able to use it after work. Will it demand to continue, or will gather dust around in the cabins.

Ivan Lukashenko (User FORUMHOUSE):

I sawed blocks D500 conventional saw for aerated concrete. Moreover, I bought the most simple, for 400 rubles. without carbide pads. No problem sawed it aerated for ordinary masonry on the total volume of about 50 cubic meters.

Ivanu Lukashenko echoed by a user with the nickname Vetalt, which is in the construction of houses bought for the workers who built him a house, a normal (non-brand) saw with carbide tipped. Saw successfully survived the building and, although a bit blunt, interesting fact: when Vetalt I bought for builders second - a more expensive saw with the "name", working by testing it in fact, returned to the old. The thing is that we first saw dense, unlike the new, was made of thick metal. Saw does not lead to side and cut a smooth, neat.

Therefore, choosing a saw to aerated concrete, do not chase the most expensive samples. For a start it is possible to manage and simple and only when needed to purchase a more expensive tool.

Sorox (User FORUMHOUSE):

I am using a handsaw for aerated concrete built a house the size of 9x9 meters. How old was she sawed, even scary to think. Saw is still in service.

How to manually cut aerated concrete

Some users said that the cut aerated concrete by hand - it is difficult and dreary occupation, and not the result of a very high quality. But there are also those who claim that the cut by hand is possible and necessary. Res a smooth, work is not drudgery. What is the reason diametrically opposing views?

In addition to proper technique cut aerocrete hand, as will be explained later, it is important - a unit you are processing. It is one thing - to cut manually block density of 400 kg / m³ and strength class B 2, and quite another - to cut aerated D600 V 3.5.

My work, as I suggested them to cut manually in aerated 3.5 poelozit saw on the block and become sad. It went more fun when I entrusted them to work with a saw-alligator. Hour practice, and they began to make additional elements with a tolerance of no more than 2 mm in the plane.

But the member of our portal with the nickname ELITE83 building a house, sawing blocks most simple hand saw. Moreover, he has cut blocks in the form of a trapezoid, for laying the round tower. At the user's calculations, it has already made more than a thousand cuts, and all the time there were no problems. Blocks sawn smoothly, the saw does not lead anywhere.

So, in addition to the density and strength of aerated concrete, an important technique of sawing and, importantly, the status of the block. To understand how to cut concrete, you can take advice RomanXRoman.

RomanXRoman (User FORUMHOUSE):

Many have problems with even saw cut aerocrete. During construction I had to cut a lot of hand saw, did not spoil a single unit. Pililos pretty simple, the only thing - it is very difficult to cut at temperatures below freezing, when gazoblok scored moisture, and she froze. Saw gets stuck and does not go.

The technique is as follows sawing.

1. Do not we press on the saw, otherwise it will start to withdraw aside. Unlearn sawing concrete, as we used to saw boards. The unit is not cut like wood. In fact, teeth crumble concrete, and this baby is removed by the same teeth.

2. Cut aerated concrete should be dry. Fir wet or frozen block, work is stopped. Because chips are not swept out, saw blade fit the unit itself.

3. To cut straight, making marks on the unit using the polygon on the three faces. On two adjacent labels do cuts to a depth of 2-3 cm. The third label is used as a control.

4. When starting to cut the block, it follows that the web is strictly followed two scheduled propylene. They are at 90 ° to each other and aligned web in two perpendicular planes. Sawing at an angle of 45 °. Do not we press on the saw. To saw off a piece of the unit does not fall at the end of work and did not get chips, sawing on a stand so that the unit lying on her completely.

5. Hacksaw choose longer, it should not just get to the end of the cut, but also good to clean propyl.

It is also possible to simplify the work of the scrap materials (boards and plywood) stuslo simplest manufacture. In this case, the saw blade will be given direction.

I Peel aerated handsaw with millimeter precision. For this, first a pencil to mark up the four sides. Then I do 2-3 cut. The block is sawn easily enough, but because process to be a lot, it would be desirable to optimize and speed up the process. Conceived to make miter box. Who says that?

Viktor Borisov (User FORUMHOUSE):

I am a self-built house of aerated concrete, and to simplify the work to make a simple miter box. This simple device is greatly facilitated cutting blocks. Block in width 37.5 cm in stuslo rises without gaps, and in cutting the block in a width of 25 cm is used for the block brick stop.

How does such a miter box, clearly seen in the following photo:

Taking it as a basis, we can make his own version of the device.

In conclusion, the article will talk about yet another embodiment, the cutting block using conventional two-handed saws for wood.

Deaddman (User FORUMHOUSE):

I have an old "are alternate", a real rarity,made in USSR! So, it is perfectly aerated concrete saws, only slightly spread his teeth and imprisoned.

So, in this article we described how to saw aerated manually. If you want to get the answer to the question, how fast sawing aerated using an electrical instrument and learn What other devices used to treat aerocrete our users, we recommend to wait for the second part articles. Look for updates on our site!
