Concrete of increased strength. Such concrete is used in the construction of structures of particular importance. For these structures, as a rule, not only strength is important, but also a small volume. Such concrete have marking names M600-M1000. In their production, only high -marble fillers and cements are used.
Road concrete.
This concrete is based on a water-cement binder. In some cases, it is used as the basis of asphalt concrete. More often, such concrete becomes the top coating of the roadway (for example, on the runway). By the way, you will also need to be washing the sewage system best after construction.
In the production of such concrete, hydrophobic cements are used. They largely increase its frost resistance.
Hydrotechnical concrete.
This concrete, as the name implies, is used in the construction of objects constantly contacting with water. The production of this material is very expensive, t. To. it should be as frost as much as possible – and water is stable.
Heat -resistant concrete.
In the construction of industrial furnaces, as well as smoke pipes, special types of cements are used. They are – clay -earth cement, Portland cement, as well as compositions based on liquid glass.
Acid -pushed concrete.
It is made of special cements that are shut with liquid glass. In the composition of fillers, no metal inclusions are allowed.
In addition to the above, construction uses many concrete of other varieties and types.
