Gray Portland Cement 32.5 R / 42.5 R / 52.5 N

There are two types of gray Portland cement: TS EN 197-1-CEM I with 42.5R and 52.5N standards. The strength of these types depends on the high amount of C3S in the cement.

These are the most popular cement types, especially in the high strength concrete class and in the construction of tall buildings. It is popular in pre-stretched prefabricated applications in particular, tunnel mould systems and in the construction of mass housing.

Portland Cement 32,5R - TS EN 197-1-CEM II/B-M (V-L) 32.5R
This Portland composite cement is in the early compressive strength group in its own class. Apart from Portland cement, it contains 35% fly ash, which is finely blended with limestone in its compounds. Thanks to the fineness of its filling material, this type of cement tightens by filling the micro pores in the concrete and improves its impermeability.

The finely blended puzzolanic materials used in the production of composite Portland cements ensures higher final strength and durability by accelerating the later age reactions and also improving resistance to external factors.

Portland Cemnent 42,5N - TS EN 197-1 CEM II / B-M (V-L) 42.5 N
This Portland composite cement contains 25% fly ash, which is finely blended with limestone in its compounds as well as Portland cement. Thanks to the fineness of the filling material it contains, this type of cement tightens by filling the micro pores in the concrete and improves its impermeability.
