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 document specifies a method for taking cores from hardened concrete, their examination, preparation for testing and determination of compressive strength. This document does not give guidance on the decision to drill cores or on the locations for drilling and does not provide procedures for interpreting the core strength results. It is recommended that before coring, full agreement should be reached by all parties on the need for core testing and how the results should be interpreted.

ISO 1920-2:2016 specifies procedures for testing fresh concrete. It specifies the following test methods: determination of consistence (slump test, Vebe test, degree of compactability, flow-table test for high‑fluidity concrete, and the slump-flow test), determination of fresh density and determination of air content by the pressure-gauge method and by the water-column method.

ISO 17785-1:2016 specifies the procedure for testing the infiltration rate of hardened pervious concrete pavement specimens in the laboratory. It is not a method for measuring the permeability of pervious concrete. The specimens can either be prepared in the laboratory or cored from field placements, but not representing field conditions. This part of ISO 17785 also specifies procedures to make and cure hardened pervious concrete samples in the laboratory.

This procedure specified in ISO 1920-12:2015 is a method for evaluating the carbonation resistance of concrete using an accelerated carbonation test. After a period of preconditioning, the test is carried out under controlled exposure conditions using an increased level of carbon dioxide to which, the vertical sides of the specimen are exposed. The test results are not designated to set performance requirements but to compare the carbonation resistance of different concretes of the same strength class, which are used in the same environmental conditions.

ISO 1920-11:2013 specifies a method for determining the unidirectional non-steady-state chloride penetration parameters of conditioned specimens of hardened concrete.
