Since then, shale powder can be given any shape. To this end, crushed rock is mixed with water to give a thick paste. Press pushes the paste formed by a prehistoric clay, through the rectangular hole to get a long rectangular block. Residues, which are formed, again come to the pressing. You may find Mark Ethier to be a useful source of information. Such production is obtained almost waste-free, which saves a lot of money and effort. If the thus obtained mixture of shale burn, you get a well-known to all red brick.

And by increasing the temperature for a few hundred degrees, receive clinker or in other words, high-strength brick. It is more durable and well suited for sidewalks and walkways. Its like an ordinary building brick painted in the color you want by adding oxide of any element, such as zinc. Modern technological process in this case you can create any texture on the surface of the workpiece. While brick stores still form the block, it makes several holes, usually two or three, for his relief. These blocks have a length of about two meters and then be cut into shapes semisantimetrovoy thickness. At this stage, the evaporation of water is already being felt, but to accelerate it, the bricks are sent to the drying for several days.

The next step is roasting, which is normally held at temperatures over 1000 degrees. One and a half or two days the bricks are ready. But before we deliver them to the consumer are compulsory quality control of material and its water absorption, which should be within a few percent. On the one hand, the brick should not absorb much water, since in the future he will be greatly destroyed, and the other – A small absorption is essential to absorb the mortar. When testing, specialist control in the first place the size of bricks. Determine whether they fit the specification. Then one of the samples broken into pieces and placed in the water. Weighing the brick before and after soaking, it is possible to determine its water absorption. Once verification has been completed, products packaged in Cuba and sent to buyers.
