TYPE I

TYPE 1 cements are obtained by grinding clinker and gypsum, and are available in strength classes of 42.5 R, 52.5 N and 52.5 R.  It is also available as a Type SR, obtained by using a special clinker with a low aluminate content, which is essential for rendering the product resistant to sulfate attacks.

These cements are particularly suitable for the construction of prefabricated structures in reinforced concrete and prestressed reinforced concrete, and other products that require very high strength with a short curing time.

Conformity

• European standard EN 197/1, which defines and specifies standard cements (separated into strength class and type), compliance criteria and the respective regulations, chemical/physical/mechanical requirements and the constituent requirements
• European standard EN 197/1, which defines and specifies special cements (separated into strength class and type), which are resistant to sulfate attack in aggressive environments: the standard also specifies the compliance criteria and the respective regulations, chemical/physical/mechanical requirements and the constituent requirements
• European regulation 305/2011 (CPR), which establishes the harmonized standards for the declaration of performance and for the use of the CE marking for building products
