Paving slabs are one of the most popular materials for arranging pedestrian areas, parks, squares and other urban infrastructure facilities. It is characterized by high strength, durability and resistance to atmospheric agents, chemicals and mechanical stress. In this article we will consider the main types of paving slabs and the technology of its production.
Types of paving slabs.
There are several main types of paving slabs, which differ in shape, size and surface.
Classic paving slabs have a rectangular shape and dimensions of 200×100 mm or 150×150 mm. It can be of various colors and textures – from smooth to embossed. Classical tiles are often used for arranging pedestrian areas in cities and on the territories of private houses.
Figured paving slabs are tiles with a non-standard shape that can imitate brick, stone, wood and other materials. It allows you to create original compositions and decorate pedestrian areas, parks and squares.
Paving slabs with a pattern are tiles with a pattern or image applied to the surface. It can be used to create original mosaics and compositions in pedestrian areas, parks and squares.
Features of the manufacture of paving slabs
Paving slabs are made from cement, sand, water and special additives that ensure their strength and durability. There are several technologies for the production of paving slabs, which differ in the method of molding and surface finishing.
The vibrocasting method is one of the most common methods for the production of paving slabs. In this method, a mixture of cement, sand, water and additives is poured into a mold and then subjected to vibration to remove air bubbles and compact the mixture. After that, the tile is kept in shape for several days, then removed and subjected to surface finishing.
The dry pressing method is a paving slab production method in which a mixture of cement, sand, water and additives is compressed in a special mold. After that, the tile is kept in shape for several days, then removed and subjected to surface finishing.
The wet pressing method is a paving slab production method in which a mixture of cement, sand, water and additives is compressed in a special mold under water pressure. After that, the tile is kept in shape for several days, then removed and subjected to surface finishing.
The surface finish of paving slabs can be different – from smooth to embossed. For this, special forms and matrices are used, which apply the desired pattern or texture to the surface of the tile.
conclusions
Paving slabs are a reliable and durable material for arranging pedestrian areas, parks, squares and other urban infrastructure facilities. It can have a different shape, size and surface, which are determined by the technology of its production. There are several basic technologies for the production of paving slabs – the vibrocasting method, the dry pressing method and the wet pressing method. Each of them has its own characteristics and advantages, which allow you to create tiles of various shapes and surface finishes.
