Introduction

The purpose of this document is to specify the requirements for cement with recycled concrete fines.

Different cements have different properties and performance. The performance tests available at the time of publication of this document (i.e. for the determination of setting time, strength, soundness and heat of hydration) have been included in this document. In addition, work is being carried out by CEN/TC 51 to identify any additional tests which are needed to specify further performance characteristics of cement. Until further performance tests are available, it is necessary that the choice of cement, especially the type and/or strength class in relation to the requirements for durability depending on exposure class and type of construction in which it is incorporated, follows the appropriate standards and/or regulations for concrete, mortar, grout, etc. valid in the place of use.

The fitness of cement with recycled concrete fines for the intended use to produce structural concrete (reinforced or not) has been experimentally assessed by testing programs, the results of which have been included in a dossier [1] approved by CEN/TC 51.

The cement types and strength classes defined in this document allow the specifier and/or the user to contribute to objectives of sustainability for cement-based constructions and of circular economy and to minimize the use of natural resources in accordance with local conditions of production.
