PRODUCTS
GRAY CEMENT

Portland cement (PC 42.5 - PC 32.5) (CEM I 32.5 R - CEM I 42.5 R)
Areas of use:PC 32.5 can be used in general-purpose construction to produce concrete where the hydration temperature and effects of sulfur do not require that special attention be given. PC 42.5 and PC 52.5 are used in construction works where highly resistant concrete is desired or where concrete with a high initial resistance to shock is required.


Composite cement (KZC/A 32.5R) (CEM V/A(S-P-Q) 32.5 R)
Areas of use:Used in ordinary construction works and in making block concrete for which a low hydration temperature is desired.


Sulfur-resistant cement (SDÇ 32.5)
Areas of use:Used in construction works in areas high in sulfates or affected by seawater; in underwater construction and in the construction of bridges, dams, and harbor substructures; in the construction of retaining walls.


Additive cement (KÇ 32.5)
Areas of use:Used in general-purpose construction, in all areas of construction not requiring early resistance, in the making of all forms of concrete where the hydration temperature and effects of sulfur do not require that special attention be given (resembles PC 32.5).

Portland composite cement (PKÇ/A- 42.5) (CEM II/A/M)
Areas of use:General-purpose construction in which additive cement is used and construction works requiring higher resistance.


Portland composite cement (PKÇ/A- 32.5 R) (CEM II /A/M 32.5 R)
Areas of use:Used in general-purpose construction in which additive cement is used, in construction works requiring higher resistance, in construction works (such as dams) where a low hydration temperature is needed, in places exposed to seawater.


Portland composite cement (PKÇ/B 32.5R) (CEM II /B/M 32.5 R)
Areas of use:Used in construction works were a low hydration temperature is required (such as dams), in places exposed to seawater, in normal construction works (since it is resistant to sulfates, chlorides, and other salts).


Pozzolanic cement (PZÇ/B-32.5 R) (CEM IV/B 32.5 R)
Areas of use:Used in general-purpose construction works where additive cement is used.


Trass cement (TÇ 32.5)(CEM II/B-P 32.5 R)
Areas of use:Used in dam, foundation, and tunnel construction works because it is highly resistant to alkali, salt, and aggressive water; in block concrete construction works where the hydration temperature must be rapid; in the construction of agricultural and industrial facilities.


Blast furnace slag cement (CEM III/A 32.5 R)
Areas of use:Used in places where corrosion is not very effective. Bolu Çimento produces ÇÇ 32.5.


WHITE CEMENT

White Portland cement (BPC 42.5-70) (CEM I 52.5 R)        
Areas of use:Precast elements, ready-mix, adhesives and fillers, architectural and decorative concrete, works of art.
