Technical purpose Cement II is a type of cement classified within the European standard EN 197-1, which defines the specifications and compositions of common cements. It is also known as Portland cement composite. The designation "Cement II" indicates that it is a cement that includes, in addition to clinker (the main component of traditional cement), supplementary materials that partially replace the clinker, making it more sustainable. This type of cement is more environmentally friendly compared to pure Portland cement (cement I) because it reduces the amount of clinker, which is the most intensive part in CO₂ emissions during its manufacturing. This makes it suitable for projects seeking to minimize the carbon footprint of construction, without compromising too much on the strength or durability of the material.
The product is marketed according to its resistance capacity, so there are two references according to this classification in the production of Ciments Terraferma. The capacity or resistance class is classified in numbers that usually range from 32.5 to 52.5 MPa. In the case of Terraferma, they have Cement II 32.5 and 52.5. The A-L and B-L classification indicates the filler content. Furthermore, the letter R indicates that the product has a high initial resistance, the letter N, on the contrary, indicates a normal initial resistance. Based on this classification, the two types of cement II manufactured by Ciments Terraferma are:
• Cement II A-L 42.5 R
Initial resistance (2 days) (EN 196-1): 22-24 MPa
Normal resistance (28 days) (EN 196-1): 48-52 MPa
Setting principle (EN 196-3): 160-200 min
Final setting (EN 196-3): 240-260 min
Expansion (EN 196-3): 0-1 mm
Insoluble residue (EN 196-2): < 1.5%
Sulfate content (EN 196-2): 3-3.5%
Chloride content (EN 196-2): 0-0.03%
• Cement II B-L 32.5 N
Initial resistance (2 days) (EN 196-1): 26-29 MPa
Normal resistance (28 days) (EN 196-1): 36-39 MPa
Setting principle (EN 196-3): 180-220 min
Final setting (EN 196-3): 240-270 min
Expansion (EN 196-3): 0-1 mm
Sulfate content (EN 196-2): 2.5-3.5%
Chloride content (EN 196-2): 0-0.03% |
