People use concrete almost everywhere, starting with laying the foundation, ending with interior work and bricklaying. Such widespread use forced people to create substances with different compositions and properties. It is impossible to just buy any random concrete and start working - first you need to make sure that the composition is normal.
1. Main qualities
The main properties and qualities of concrete are different and it directly depends on them the price of concrete. Among the popular ones, the following can be singled out.
2. Corrosion resistance
It shows how strong and durable the concrete is. Resistance to external chemical and physical influences is tested. This includes washing and erasing.
3. Cold resistance
The material is characterized by its resistance to freezing or thawing. The density of the stone is taken into account, where there should not be many pores and water, which destroys the structure when it freezes. That concrete will be durable https://tehbeton.com.ua/ru/, which is not "afraid" of water. It will also not let air in, which will save the building.
4. Waterproofness
This is necessary so that the concrete does not wash out in a wet environment. Water resistance can be increased with the help of additives that must be added to cement.
Really good concrete should have all useful properties.
Concrete types
There is no concrete that would be absolutely universal and help everywhere. In each case, it is necessary to select a separate type. There are more than thirty of them. Each differs in properties, characteristics and solidification.
Concrete is divided into two types: general construction and special purpose.
Portland concrete is a viscous substance that is used to make most, namely 99% of cement. Perfectly suitable for creating monolithic concrete, finishing mortar, products from reinforced concrete, manufacturing tiles for sidewalks.
Portland slag concrete contains a small amount of slag. It gradually hardens without releasing much heat. It is suitable for large buildings and structures, it practically does not deform, it is resistant to water penetration, it is not affected by high temperatures and is cheaper than conventional production.
Fast-hardening material helps concrete gain strength faster. It is used during the construction of high-rise apartments.
Due to active additives, plastic fits better. Resistant to corrosion and frost, it is used for road, airfield and hydrotechnical repairs.
Tsvetnoi is used in the production of monolithic buildings, which do not require additional finishing.
White concrete is created using white clay. It is used for the production of concrete and plaster mix. The basis for the production of colored cement.
Damping concrete perfectly withstands high temperatures, up to 150 degrees Celsius. Durability is a feature. This is necessary for use in an oil and gas well. It isolates wells from groundwater.
