What is a cinder block?
We all heard and know a fairy tale about three piglets. More than one generation of people has grown up on this fairy tale, it clearly articulates the principle: a reliable house is a stone house. And indeed, if you look at the ratio of stone and wooden houses, the difference will not be in favor of the latter.
At the same time, the price of building a wooden house plays an important role. Therefore, many private developers and choose their choice on a stone house. And the material when building such a house is a brick or cinder block.
Slagblock is a popular building material obtained in the process of vibrocompression concrete mix in a special form. It is used for erection of bearing walls, internal walls and partitions on the object under construction.
Advantages of this building material are low cost in self-manufacturing, as well as in the high speed of erection of walls.
To make this building material, you do not need to have any special knowledge. Despite the technical equipment of the enterprises where the slag blocks are made, the production technology is quite simple, and all the equipment can be simplified to the size of a home master.
How to make a cinder block with your own hands, you can learn from the experience of seasoned builders. Of course, for this you will need not only the tools that any master has, but even additional spending on equipment will pay off with a significant decrease in the total cost of construction.
Slag blocks - what you need to know?
In the production of this material on an industrial scale, special shapes, presses and vibrating tables are used. In order to make slag blocks with their own hands, home craftsmen also make a form, most often of wood. It is possible to construct such a form on almost any size of the blocks.
In fact, this form is just a formwork for a concrete mix. To facilitate the excavation of the cinder block from this form, it is often made folding and even without a bottom, underlaying under the form of cellophane, which, as is known, does not adhere to the cement.
For the device of voids in a material usual bottles which fill with water and are pressed in necessary places directly in concrete are applied. But for the convenience and quality of the product, the objects with which it is planned to make voids are better clearly fixed in this form, by attaching them to the lid or bottom.
Standard slag size is 390х190х188 mm, where the first is the length, the second is the width, and the third is the height. The weight of the finished product with such dimensions is usually about 20 kg, so these parameters were given only as an example, with independent manufacture of blocks they can be varied.
In , the composition of slag block, based on the name, must include slag, ash and other wastes. But in practice, in the production of this product, any available materials( gravel, screening of gravel, sand, expanded clay, brick waste) are used.
Solution for slagblocks should be made medium flow. You can produce batch manually or in a concrete mixer. After pouring a concrete solution into the mold, it is advisable to "tear down" either a small deep vibrator, or simply tapping the entire shape from the outside with a hammer. This is done so that all components of the solution are evenly distributed in shape, and all the air bubbles come out.
It is possible to remove the finished product from the mold not earlier than 3-4 days after pouring. When drying the finished material, avoid possible drying, so in hot weather it is necessary to cover the blocks with a damp rag. Prescribed strength of the material accumulates only after 28 days.
How to put a cinder block or construction of a house from
cinder blocks. Despite the fact that there are enough offers on the construction services market for building houses from the material under consideration, we will try to figure out how to put the cinder block in order not to resort to the help of specialists.
Masonry from wall blocks is carried out on the foundation. To cement the blocks, a cement slurry is used. Do not save on the solution, becauseThe cinder block grasps long enough, and before that it undergoes fractures. The given building material is thick enough, therefore it is possible to manage a laying in half-block, only special attention will be necessary to be given to warming of walls.
Before the beginning of a laying out expose corners by means of a building level, then between them the building cord which will become a reference point for a laying, also its original controller on a horizontal and a plane is pulled.
At first, the corners are laid out, then the space between them is filled. If you need half-blocks in the process, you can make them from whole blocks, cutting them with a diamond drill or abrasive wheel.
To add plasticity to the cement slurry, special plasticizers sold in building stores can be added to it. Slag-block brickwork is almost identical to brickwork, it is made according to the same rules and norms as brick.
