Expanded clay: its types and some properties
Claydite is one of the most popular and popular materials in the world, which is used in the following jobs:
- production of building blocks;
- production of the so-called "warm" laying;
- insulation of the roof, foundation, facade and other structural parts of structures and buildings;
- soundproofing work;
- construction of bridges, roads and dams (here the expanded clay is used as a moisture-proof material);
- water flow filtration;
- heat insulation of pipelines of various types;
- haydite is used, oddly enough, even in plant growing (you can often see some laying a few clay blocks on the bottom with a flower pot to provide good drainage for the plant).
In general, expanded clay is a material of wide consumption. The most important property of claydite is its unusually low cost (the production process of this material is very simple and cheap - hence the relatively low price).This material is implemented by many Samara companies, but not always its quality really meets the high criteria of the modern construction industry. However, there are also time-tested manufacturing companies. For example, expanded clay plus can boast the highest quality of expanded clay produced, as well as low price and the possibility of delivery to all regions of the country without exception (and even beyond its limits, by the way).
By itself, claydite has the following properties:
- moisture resistant;
- It is an excellent refractory material (it simply does not burn);
- a light weight;
- ease of production.
This building material is usually divided into fractions (the size of individual grains of expanded clay). A small fraction (these are grains with a thickness of 10–20 millimeters) is used primarily for filling the roof or foundation. The middle fraction (from 20 to 40 millimeters) has the lowest bulk density, is used most often to fill the attics and basements. There is also a so-called claydite sand (fraction - up to 5 millimeters inclusive), which is used as an additive when pouring the foundation, manufacturing concrete walls and other similar structures.
When buying material, it is important to ensure that it is perfectly dry.Use in the construction of expanded clay, which has a large initial moisture content, is completely prohibited. This must be taken into account.
