Cinder block - universal todaybuilding material, which has excellent heat and noise insulation properties. Such characteristics of the material due to the technology of its manufacture. After cinder block - a hollow building material, the vibration generated by the shrinkage of concrete in special molds. A hollow cinder block is 30% of its total mass.
The size of the finished cinder block is 390h190h185 mmwhich makes the material extremely durable with its comparatively low weight. However, the owner, who decided to produce their own material, the right to decide what kind of values do blocks for a more agile and easy to work with them later.
Slag blocks for exterior and interior masonry walls are different from their competitors reasonable price and a full environmental friendliness. Especially if made personally.
Production of cinder blocks with their own hands will give an opportunity to significantly save the family budget and at the same time quickly and efficiently build desired building.
For the manufacture of cinder blocks at home, you will need these tools:
- Seeder for sand;
- Molds for casting solution therein;
- Concrete mixer or conventional trough for mixing cement;
- Vibrating table (or hammer);
- Bucket and spade;
- Detached trays for drying finished cinder block.
This vibration table for their production can be purchased, and the form for future blocks can be made independently.
For this it is necessary to take two long boardsa minimum height of 190 mm and connect them to the sides by wooden partitions, creating a distance between 185 mm long parts. This can be done by forming a hacksaw handy slots for all four design details. Now, the side panels are removed and dress in your desired time.
By the same principle we do partition in the formwork for the future of cinder blocks at a distance of 390mm from each other. You should have no more than five or six molds, cells for future building material.
Finished shuttering form can be set toa large piece of heavy oilcloth. This will be the bottom of our form. The design is ready. It remains to prepare plastic bottles filled with water. They will be the basis for the formation of hollow holes.
If you want to go to the production of cinder block more professional, then obzavedites prepared metal molds, in which will pour a solution.
To cinder block home has turned out no worse than the factory, it is necessary to know the exact proportion of bulk mixing of strong and reliable concrete and slag solution. So, you will need:
- Cement grade 400 or 500;
- Slag (burned coal ash, minor broken brick, concrete block);
So, take one part (bucket) cement, 3 parts(Buckets) and 5 parts of sand (buckets) slag. For bulk add 0.5 buckets of water and knead the solution. You can use both electric concrete mixer and mix the solution with a shovel and a large capacity.
Thus, the solution and equipment are ready. You can start making.
If you are using the means at hand and donot in a hurry, in this case you do without the vibrating table. You need to fill in the resulting solution by one-third in the form. Then hammer carefully to tap the wall formwork form around the perimeter. This will allow the solution to sit properly. Then again add another third solution, and again with a hammer rattles shaped perimeter.
Now it is possible to insert filled bottles plastic solution at the same distance from each other. So we form the necessary hole in the hollow of each cinder blocks.
Filled with building material leave for 2-4 days before the drying, and then gently remove the blocks from the formwork (removing side panels) and we arrange neatly on trays to dry.
If you decide to use a metal mold and a vibrating table for the production of slag blocks, the process of their manufacture will look like this:
bntonno-slag mixture is poured into metalform and set on the vibrating table. When the solution will be filled by one-third, is to include equipment for 10-15 seconds and allow the cement to pass a good shrink. Thus you will be able to expel all the air bubbles from each cinder block.
Then again, and again pour the solution include vibrating equipment literally a few seconds.
These cinder blocks can also be removed only after 48-96 hours.
Already formed and dried by cinder blocks willready to use within 28 days after their production. It was during this period, the solution is gaining its strength, and the cinder block, made at home, it is the most durable and suitable for construction.
Now you have to sketch the future building plan and build it with his own manufactured building materials.
Good luck and durable structure!
