It is literally impossible to find a material as versatile as concrete. Today, any construction project can hardly be done without it. It is used in literally all cases: housebuilding, creating of bridges and tunnels, laying of roads and highways.
The possibilities of application are endless.
It is the large number of concrete types that makes this material so versatile. Some types of concrete are more durable, while others allow for thermal insulation of structures and protect them from moisture. Therefore, it is necessary to understand the characteristics of each type in order to use concrete correctly in your work.
There are three grades of this material:
M — means concrete strength;
F — determines frost resistance;
W — resistance to moisture.
The type of filler and the amount of binding agent determines the grade of the mixture. The latter include: slag, cement, construction waste, gypsum and other materials. The additive used in concrete determines its plasticity and hardening characteristics.
Concrete is classified according to its application:
- General purpose mixture. It is used to create floors, foundations, beams.
- Special purpose concrete. It has special properties such as resistance to vibration and other external factors.
- Concrete mixture for hydraulic engineering purposes. Obviously, it is used to create structures that are fully or partially underwater.
This material is also classified according to the binding agent added to its composition:
- Silicate concrete. Suitable for creating blocks, slabs, beams, etc.
- Gypsum concrete. It is used to create floors in buildings.
- Slag-lime mixture. Suitable for pouring foundations, creating walls and stairs.
- Cement concrete. Universal and used for almost all purposes.
- Special concrete. It contains additives that make the material resistant to certain external factors.
- Polymer cement mixture. It has anti-corrosion properties.
According to the degree of strength, concrete mixtures are divided into:
- Lightweight.
- Heavy.
- Extra heavy.
