CEM II / B-M (P-W-L) 42,5 N

CEM II / B-M (P-W-L) 42,5 N is a Portland fly ash - pozzolan - limestone cement suitable for civil engineering, building applications, ready-mixed concrete and concrete products. In comparison with CEM I cement, it has higher sulphate resistance and a lower heat of hydration.

It is based on Portland type clinker mixed with cementitious materials. According to ELOT EN 197-1 CEM II / B-M (P-W-L) 42.5 N is a Composite Portland cement with strength category 42.5. It conforms to the requirements of ELOT EN 197-1 and carries a CE Mark.

 

Applications

Contractual concrete production.

Marine concrete.

A moderately low heat cement to reduce the thermally-induced stresses in large pours.

Can be used in most applications, where CEM I Portland cement or CEM IV pozollanic cement are used.

 

Reference should be made to the Greek Concrete Norm KTS 97.

 

Properties

Grey in color

Consistent strength meeting all the conformity criteria of ΕLΟΤ EN 197-1.

Compatible with admixtures.

Trial mixes are recommended to determine the optimum mix proportions.
