CEM I 42.5R

Cement type: CEM I 42.5R, the Bezdobavochny portlandtsement, type I with a high initial durability

The defining characteristics: Superuniformny, high initial durability for fast works

Producer: LAFARGE CIMENT (MOLDOVA) of S. A.

Standard: SMV SR EN 197 - 1 A1: 2007

Packing: PILE

CEM I 42.5R bezdobavochny Portlandtsement with a high durability at early age. The main component is Portlandtsementny clinker (95 - 100) and an additional component (0 - 5% ).

Scope:
According to the existing standards/standards of CEMFORTEXTRA it can be applied to the following types of works:

Advantages:
• Fast curing of concrete
• High durability of concrete
• It is most suitable for an igotovleniye of high - branded concrete
• It is most suitable for works in cold time
• Suitable for production of concrete in buildings, with low, average and high extent of moistening (kitchen, shower and washing residential and industrial buildings; cellars, pools, tanks)
• Mechanical load of attrition: moderate, intensive and high - intensity
• It is steady against impact of carbonate corrosion
• It is steady against impact of corrosion of chlorides

Recommendations:
• Observe requirements concerning transportation and storage
• Observe requirements concerning laying and care of concrete
• Observe a water cement ratio (in/C)
• After concrete laying, protect a surface from direct exposure to sunlight, a rain and wind

Contraindications:
Do not fill in concrete at a temperature below 5º C without protivomorozovy additives.

Characteristics

Physics - mechanical characteristics sogolasno the SMV SR EN 197 - 1 A1: 2007 standard
• Skhvatyvaniye term - the beginning (min. ) - minim 60
• Uniformity of change of the volume (mm) - max. 10
• Durability on compression (MPa) in 2 days - we will pass 20
• Durability on compression (MPa) in 28 days - minim 42,5 - max. 62,5

Characteristics of concrete on the basis of CEMFORT EXTRA:
Concrete on the basis of CEMFORT EXTRA quickly hardens and has high initial and final durability, possesses high frost resistance. Concrete on the basis of CEMFORT EXTRA easily prepare and keep within and can be used both in the manual and mechanized way, without additional knowledge and skills. As CEMFORT EXTRA is quick - hardening, the final product turns out for the short period, i. e. working hours are saved and productivity increases.
Concrete on the basis of CEMFORT EXTRA, allocates a little bigger amount of heat unlike usual concrete that allows to perform successfully works in a cold season.
