Expanded clay (expanded clay gravel, expanded clay gravel, expanded clay sand) is a porous substance made of burned clay. Due to the fact that alloy clay is subjected to a sharp thermal shock, it increases in volume (this achieves a porous internal structure), and its rapidly melted outer surface acquires strength and becomes resistant to external exposure.
The use of expanded clay: it is used as the basis for repair and laying in road construction, in agriculture, for filtering in sewage drains, as a filling of light concrete, as pounds in thermal insulation work. In matters of improvement of territories and personal plots, expanded clay, perhaps one of the most favorite materials, it is not only practical, but also acts as decorative material. When growing indoor plants, it has proven itself as a drainage. In the hydroponics, the quality of expanded clay is appreciated easily to absorb moisture and give it badly (this is due to internal porosity and a solid outer shell).Ceramzit is sold in bulk or in bags, and if there is a need to ennoble the territory and fall asleep near the house or put it in pots for indoor plants, then expanded clay in bags, of course, the most suitable option, and there is no need to acquire a large batch for this, which is very Convenient and economical.
The main advantage of expanded clay over other materials is its origin. This material of natural origin, it is environmentally friendly and absolutely safe, has excellent sound insulation, otherwise it has a low weight, microorganisms are not formed in it, resistant to frost. In addition, this is a fairly cheap material used in construction.
