This document describes the procedure for obtaining the non-steady-state chloride migration coefficient of specimens of hardened concrete at a specified age. 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 is electrically conductive or porous this will influence the magnitude of chloride migration. This fact has to be taken into account when establishing threshold values. It prevents comparison of chloride migration values between concretes if the aggregates show a difference of half an order of magnitude (higher or lower) of chloride migration.
Similar influence may be seen when metallic or electrically conducting fibres or particles are present.

This document specifies a procedure for carrying out impressed current electrochemical chloride extraction from chloride bearing concrete in existing structures. It is applicable to atmospherically exposed parts of structures with ordinary reinforcement and/or post-tensioned tendon ducts embedded in concrete. In the latter case, it is essential to verify that there is no risk of hydrogen embrittlement, if necessary by conducting trials and installing monitoring during the treatment.
This document does not apply to concrete containing pre-stressing steel which can suffer hydrogen embrittlement during chloride extraction, or to concrete containing epoxy-coated or galvanized reinforcement.
In case of post-tensioned, pre-stressing concrete, the endangered tendon strands may be shielded by the tendon ducts from unwanted and/ or exceeded polarization into the cathodic range and respective water reduction.

This document specifies requirements for the properties for silica fume, siliceous fly ash and ground granulated blastfurnace slag for use as a type II addition for production of concrete conforming to ISO 22965. Additions according to this document can also be used in mortars and grouts. This document applies to the silica fume which is a by-product of the smelting process used to produce silicon metal and ferro-silicon alloys. Fly ash produced with other types or higher percentages of co-combustion materials than those provided for in this document is outside the scope of this document. Ground granulated blastfurnace slag containing any added materials other than grinding aids and/or gypsum (calcium sulfate) is not within the scope of this document. It is not within the scope of this document to specify provisions for the practical application of additions in the production of concrete, mortar or grout, i.e. requirements concerning composition, mixing, placing, curing, etc. NOTE Some rules are given in ISO 22965‑2, e.g. provisions on general suitability and use of additions.

This document gives the determination of aggregate crushing value (ACV) of aggregates. This gives a relative measure of the resistance of the aggregate crushing under the gradually applied compressive load. The method is applicable to aggregates passing a 14,0 mm test sieve and retained on a 10,0 mm test sieve. For other size fractions, a recommended method is described in Annex A. The aggregate size fraction taken for this test can also be as per the relevant national standards. NOTE Minor variations in grading divisions can be allowed in respective national standards. The method is not suitable for testing aggregates with an aggregate crushing value higher than 30. In such cases, the method described in ISO 20290-4 is applicable.

This document gives the test method for determination of ten percent fines value (TFV) of aggregates. This method gives a relative measure of the resistance of the aggregate crushing under the gradually applied compressive load. It covers two sets of procedures: — the first procedure is applicable for aggregates tested in dry condition; and — the second procedure is applicable for aggregates tested in a soaked condition. NOTE 1 Generally, the test can be done under dry conditions. However, the engineer in charge can choose to test them in soaked condition, if necessary. The method is applicable to aggregates of different strengths covering both weak and strong aggregates. It is applicable to standards aggregates, i.e. passing a 14,0 mm test sieve and retained on 10,0 mm test sieve. National standards can also exist for the aggregate size fraction to be taken for this test. In case this definite size fraction is not available, the test can be made on other sizes, given in Annex A. The comparison of results of non-standard sizes with standard size aggregates is not possible due to lack of available data. NOTE 2 Minor variations in grading divisions can be allowed in respective national standards.

This document covers the method for determining the setting time of concrete with slump greater than zero, by testing mortar sieved from the concrete mixture. The initial setting time and the final setting time are the time intervals required for the mortar sieved from the concrete mixture to reach the specified values of penetration resistance after the initial contact of cement and water. The method can be used for determining the effect of variables such as temperature, type and content of cement, concrete mix proportions and admixtures, on the time of setting and hardening characteristics of concrete. This test method is applicable under controlled laboratory conditions, as well as under field conditions.

This European standard specifies a method for determining the consistence of fresh concrete by the
slump test.
The slump test is sensitive to changes in the consistence of concrete, which correspond to slumps
between 10 mm and 210 mm. Beyond these extremes the measurement of slump can be unsuitable and
other methods of determining the consistency should be considered.
If the slump continues to change over a period of 1 min after withdrawing of the cone, the slump test is
not suitable as a measure of consistence.
The test is not suitable when the declared value of D of the coarsest fraction of aggregates actually used
in the concrete (Dmax) is greater than 40 mm.

The test is suitable for specimens having a declared value of D of the coarsest fraction of aggregates actually used in the concrete (Dmax) not greater than 40 mm.

This European standard specifies a method for determining the consistence of fresh concrete by determining the degree of compactability.
The test is suitable for specimens having a declared value of D of the coarsest fraction of aggregates actually used in the concrete (Dmax) not greater than 63 mm.
If the degree of compactability is less than 1,04 or more than 1,46, the concrete has a consistence for which the degree of compactability test is not suitable.
