High-strength pure Portland cement for concretes requiring the highest strengths and a fast form removal or load of the structure, also suitable for concreting in cool weather.

Characteristics

CEM I 42,5 R is characterized by a rapid increase in strengths, attaining high early and final strengths (after 2 days in the range of 29 to 36 MPa, after 28 days from 57 to 62 MPa). During hardening, this manifests itself by a high development of heat of hydration.

Use

• concretes of high strength classes and concretes where fast demolding is required
• demanding structures made of reinforced concrete and plain concrete (bridge structures, pillars, etc.)
• production of prefabricated elements and ready-mixed plasters
• concrete pavements and concrete surfaces subject to high stress
• industrial floors
• all kinds of industrial and civil structures

Advantages

• the rapid increase in early strengths enables a
• quick demolding of products
• quick walk-on-ability of concrete surfaces
• quick load of the concretes produced
• high early and final compressive strengths
• good workability, colour fastness and low volume changes
• the high development of heat of hydration enables concreting even in cool weather
