Cement
Cement (a word derived from the Latin word “caementum” meaning “gravel, broken stone”) is artificial inorganic binder in powder form, one of the basic building materials. When mixed with water solutions or other liquids form a plastic mass, and during solidification it forms a stone-like body.
Key purpose is making concrete, building mortars or construction mixes.

Special features |
|
PC 500 D0-N |
For making high-strength precast, usual and prestressed concrete structures; for hydraulic structures (in fresh water); for exterior parts of massive cast-in-situ concrete structures; for thin-wall cast-in-situ structures, during construction of concrete work with quick stripping of formwork |
Increased frost resistance |
|
PC 400 D0-D |
Concrete for road and airport pavements, concrete pressure and free-flow pipes, concrete sleepers, bridge structures, high-voltage power transmission line poles, railway catenary and lighting poles |
Frost resistance |
|
PC 400 D20 |
For concrete and reinforced concrete cast-in-situ structures |
Increased water impermeability, crack resistance, improved time strength growth kinetics, concrete placeability, low efflorescence on the surface of products |
|
SPC 400 |
For cast-in-situ concrete and precast reinforced-concrete structures, manufactured with steaming, for internal-massive concrete hydraulic and underground; for mortars, etc. |
For structures subjected to alternately drying and wetting. Compared with subtype A cement, subtype B cement has increased salt resistance and water resistance. The most uniform strength gain during regulatory periods of hardening. |
