cement mortar that is respectful of the natural environmental
and manufactured from steelmaking slags; by-products that
are generated in the steel industry and recycled as
siderurgical aggregates.
conformity of the product in relation to its declared
performance.
The products commercialized in the European Union with
harmonized standards should carry the “ CE Marking ”; which
rather than a quality guarantee is an identification of a
technical nature that indicates that the product complies with
the standard that affects it; a necessary legal requirement for
its commercialization.
Steelmaking slags are classified as industrial waste that can
be transformed into products through their recycling; in
accordance with Directive 2008/98/EC of the European
Parliament and of the Council of the European Union of 19
November 2008 [4]. This action plan constitutes an
opportunity to improve environmental conditions in Spain; in
accordance with the “ Programa Estatal de Prevención de
Residuos 2014-2020” (State Program for Waste Prevention)
[5] and the “ Plan Estatal Marco de Gestión de
Residuos” (PREMAR) (State Waste Management Framework
Plan) 2016-2022 [6].
The “CE Marking ” displays all the information referring to a
construction product with a specific declaration of its
performance and essential characteristics; following the
application of either the relevant harmonized standards or the
approved European technical tests to which it has been
subjected. The product manufacturer must do the “ Declaration
of Performance ” or; if applicable; the importer; distributor; or
the representative.
2. M ETHODOLOGICAL PROCESS
This new approach determines that the manufacturers of
construction products should establish measures for verification
by means of material tests; controlling the manufacturing
process or conducting follow-up of their behaviour in terms of
performance; in accordance with the requirements and
demands of the System of Assessment and Verification of
Constancy of Performance (AVCP) for the CE Mark.
Mortars designed by the Building Engineering Research Group
of the University of Burgos have been used for the elaboration
of the CE Marking Technical File of mortars manufactured with
steelmaking slags as aggregates. These mortars have been
characterized both in fresh and hardened state; and have
undergone durability tests [7-9].
Subsequently; in order to determine “Declaration of
Performance” of mortars; the rest of the tests included in the
Standard EN 998-1 [10] (rendering and plastering mortars)
and the Standard EN 998-2 [11] (masonry mortars); have
been carried out.
The new Regulation determines that manufacturers of
construction products should prepare a technical data sheet; in
accordance with the required AVCP system; to verify the
product characteristics and to issue the “ Declaration of
Performance ”; a procedure that was not contemplated in
Directive 89/106/EEC [2]. The CE marking can only be
affixed to the product; if the corresponding technical data
sheet has been completed for the “ Declaration of
Performance ”; supported by the technical documentation
(tests; trials; verifications).
According to the Systems of Assessment and Verification of
Constancy of Performance (AVCP) for the CE Marking of
mortars designed with steelmaking slags as aggregates;
System 4 for Rendering and Plastering Mortars and Systems
2+ and 4 for Masonry Mortars were used respectively.
Finally; the CE Marking Technical File of mortars will be
completed by the elaboration of the CE Mark; for its inclusion
in documents; specifications sheet; packaging and other items
necessary for its commercialization.
In Spain; the application of the European Rules on Construction
Products or Energetic Efficiency was transposed into the
“ Código Técnico de la Edificación CTE” (Technical Building
Code) [3]. This document; also based on performance; defines
the participation of the different agents in the building process
through the sharing of experience acquired in the course of
their profession.
3. P REPARATION OF THE TECHNICAL DATA SHEET
Two avenues can be followed for the preparation of the
technical data sheet:
In the case of construction masonry mortars; the manufacturers
should verify that their products comply with the so-called
“ essential characteristics ” according to the applicable
harmonized standards; in accordance with a pre-established
test plan. In addition; controls over the factory production
process must be in place and; after some time; verification of
their behaviour at the work site where they have been used.
The aim of this work is to develop a Process of CE Marking
and Certification ; at a laboratory scale; of an innovative

CE marking of the product following the ECS (European
Committee for Standardization) using the harmonized
standards applicable to the product; in this study;
Standard EN 998-1 [10] (CE Marking for rendering and
plastering mortars ) and Standard EN 998-2 [11] (CE
Marking for masonry mortars ).
