(European Organization for Technical Assessment) process;
using the European Assessment Documents (EADs).
European Parliament and of the Council [1]; which establishes
the conditions for the commercialization of construction
products. The Systems of Assessment and Verification of
Constancy of Performance (AVCP) for application to mortars
designed with steelmaking slags as aggregates are System 4
for Rendering and Plastering Mortars and Systems 2+ and 4
for Masonry Mortars.
In this study; the procedure established by the European
Committee for Standardization (a) will be followed; because
European Harmonized Standards are applicable both to
construction mortars and to rendering and plastering mortars.
The Resolution of 6 April 2017; from the Dirección General de
Industria y de la Pequeña y Mediana Empresa (General
Directorate of Industry and Small and Medium Enterprises)
[12]; updates the list of Harmonized Standards; in accordance
with the contents of Regulation (EU) Nº 305/2011 of the
Table 1 shows the tasks that the participants in the process
have to follow. In this study; the actions of the Notified Body
will not be considered; due to the fact that its intervention
concerns the mass production process.

The essential characteristics with which the mortars have to
comply are included in the standards of rendering and
plastering mortars EN-998-1 [10] and masonry mortars EN
998-2 [11].
In accordance with the procedures; a technical data sheet with
the standards applicable to the product for the determination
of performance will be drafted. In this research work; mortars
dosed with steelmaking slags as aggregates either for use as
rendering and plastering mortars on vertical surfaces or for
use as masonry mortars to lay stone and brickwork will be
assessed. This assessment of performance will be based on the
laboratory-scale test results.
Subsequently; a set of tests will be established; in order to
determine the performance of the material and its
characteristics; with the objective of proceeding to its
classification; in accordance with European standards. In Fig.
1; the set of tests necessary for the Declaration of
Performance of CE Marking of both the rendering and
plastering mortars and the masonry mortars are shown.
A Unique ID-Code is assigned to the product (Reference;
Commercial Name-Manufacturing Code) for its inclusion in the
CE-Mark. In Table 2; the Code assigned to each mortar under
study in accordance with its use is shown: MSwr is a mortar
dosed with steelmaking slags as aggregates and a water
retention admixture and MSap is a mortar dosed with
steelmaking slags as aggregates and an air entrainment
admixture.
Type of Mortar Standard Code
Rendering and plastering mortar EN 998-1 MSwr
Masonry mortar EN 998-2 MSap
4. P RODUCT DESCRIPTION
Iron and steel production systems generate different types of
slag by-products; with different characteristics and properties;
in accordance with the raw material in use and the reagents
added for their transformation.
The environmental impacts of these waste products range from
visual impacts; due to the occupation of extensive surfaces for
their deposition and storage; to the filtering of toxic chemicals
such as toxic metals into the soil; as these toxins are
decomposed by the action of atmospheric agents.
