"Press and vibration method"

In the vibration method, first the mortar, which includes water, cement, sand and the desired color, is poured into a rubber mold. Also, it is dried in two ways, either in the sun or in a steam room. Also, in this method, pressing devices called female tables are used, which can be mobile and fixed, and in fact, the fixed type has a high vibration pressing power. In the pressing method, which are divided into dry pressing and wet pressing, concrete is prepared in a traditional way, and after pouring it into metal molds, it is pressurized using a press machine, and this pressure causes all the water to come out of the mortar. Come. This is also the reason for the resistance of these tables in regions with frost. "Traditional Method"

In the traditional method, concrete is poured into the molds and after the concrete takes the shape of the concrete mold and is processed, the table is removed from the mold. They say that to increase the life of the table, the ratio of water to cement is low. Also, in order to increase the strength of this type of concrete table against freezing and cold, foaming materials are used.
