SupraCEM
high-strength Portland cement 42.5 R

High-strength 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 thanks a high level of hydration heat.

Characteristics

CEM I 42.5 R is characterized by a rapid increase in strength, while achieving a high initial strength and final strengths (after 2 days in the range of 29 to 36 MPa, after 28 days from 57 to 62 MPa). During solidification is manifested by a high development of heat of hydration.

Usage

• 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.)
• small concrete elements (blocks, paving, etc.)

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
