Cement for all conventional concrete works requiring high final strengths with a slower increase in strengths and a longer workability. Cement suitable for the production of ready-mixed concrete and for stabilization of soils. The lower development of heat of hydration also predetermines it to concreting in warm weather and to massive structures.

Characteristics

CEM III/A 42,5N is a cement produced by fine grinding of Portland clinker, granulated blast-furnace slag and gypsum. It attains 2-day strengths ranging from 15 to 20 MPa and standard 28-day strengths of 48 to 55 MPa.

Use

• monolithic and massive concrete structures
• plain concrete and reinforced concrete of common strength classes
• concrete structures within water structures
• hard surfaces made of concrete
• concretes and concrete elements exposed to mechanical load
• subconcretes and cement screeds
• production of small concrete elements
• stabilization of soils

Advantages

• very good workability of concretes and soundness
• low development of heat of hydration and a gradual increase in strengths
• high final strengths which increase continuously within 90 days from the creation of the mix
• a light colour of the resulting concrete
• the optimum slag content causes higher resistance to moderately aggressive environment (XA1 environment)
