Testing hardened concrete - Part 18: Determination of the chloride migration coefficient

Testing hardened concrete - Part 18: Determination of the chloride migration coefficient

This document specifies the procedure for obtaining the non-steady-state chloride migration coefficient of specimens of hardened concrete at a specified age (see Annex A). The test procedure does not take into account any interaction of concrete with the saline solution over time. The test result is a durability indicator with respect to the resistance of the concrete investigated against chloride penetration.
The test procedure does not apply to concrete specimens with surface treatments such as silanes.
If the aggregate or any other embedded elements (such as metallic fibres or conducting particles) are electrically conductive, this will influence the magnitude of chloride migration. This fact is taken into account when establishing threshold values. It prevents comparison of chloride migration values between concretes if the aggregates induce a difference of half an order of magnitude (higher or lower) of chloride migration.

It can also be used to specify products for which there is no standard. Not all of the requirements (Clause 4) of this standard are relevant to all precast concrete products.
Some European product standards refer to this standard. They can include specific provisions that take precedence over the provisions of this standard.

Testing of hardened concrete - Determination of electrical resistivity
EN 12390-19:2023

This document describes a method for determining the electrical resistivity of concrete in water saturated conditions. Two methods of measuring the resistivity are standardized: the volumetric method (see 3.1.3), which is the reference method, and the surface method (see 3.1.4).
NOTE   The volumetric method is applicable to cast specimens or cores, while the surface method is suitable for use on cast specimens, cores and on construction site, but not all these applications are covered in this document.
The method can be applied to the normal range of concretes covered by current standards. It does not cover the concretes made with porous aggregates or having metallic components.
The use of resistivity to assess the potential for corrosion of reinforcement in existing structures is not specified in this document.
The use of resistivity to assess cores taken from an existing structure, which need pre-condition on water saturation, is not directly specified in this document.

Sustainability of construction works - Environmental product declarations - Product Category Rules for concrete and concrete elements
EN 16757:2022

This document complements the core rules for the product category of construction products as defined in EN 15804:2012+A2:2019 and is intended to be used as a c-PCR in conjunction with that standard.
This document applies to concrete and concrete elements for building and civil engineering, excluded autoclaved aerated concrete.
This document defines the parameters to be reported, what EPD types (and life cycle stages) to be covered, what rules to be followed in order to generate Life Cycle Inventories (LCI) and conduct Life Cycle Impact Assessment (LCIA) and the data quality to be used in the development of EPDs.
In addition to the common parts of EN 15804:2012+A2:2019, this document for concrete and concrete elements:
-   defines the system boundaries;
-   defines the modelling and assessment of material-specific characteristics;
-   defines allocation procedures for multi-output processes along the production chain;
-   defines allocation procedures for reuse and recycling;
-   includes the rules for calculating the LCI and the LCIA underlying the EPD;
-   provides guidance/specific rules for the determination of the reference service life (RSL);
-   gives guidance on the establishment of default scenarios;
-   gives guidance on default functional units for concrete elements.
This document is intended to be used either for cradle to gate with options or cradle to grave assessment, provided the intentions are properly stated in the system boundary description.
Within the construction works context, a cradle to grave declaration delivers a more comprehensive understanding of the environmental impact associated with concrete and concrete elements.

This European Standard covers:
- classification related to consistence of wet mix;
- environmental exposure classes; young, hardened and fibre reinforced concrete;
- requirements for constituent materials, for concrete composition and for basic mix, for
fresh and hardened concrete and all types of fibre reinforced sprayed concrete;
- specification for designed and prescribed mixes;
- conformity.
This European Standard is applicable to wet mix as well as dry mix sprayed concrete.
The substrates to which sprayed concrete can be applied include:
- ground (rock and soil);
- sprayed concrete;
- different types of formwork;
- structural components constituted of concrete, masonry and steel;
- drainage materials;
- insulating materials.
