This European Standard shall be given the status of a national standard, either by
15、 publication of an identical text or by endorsement, at the latest by April 2007, and conflicting national standards shall be withdrawn at the latest by April 2007. This standard forms part of a series of tests for chemical properties of aggregates. Test methods or other properties of aggregates wil
16、l be covered by Parts of the following European Standards: EN 932 Tests for general properties of aggregates EN 933 Tests for geometrical properties of aggregates EN 1097 Tests for mechanical and physical properties of aggregates EN 1367 Tests for thermal and weathering properties of aggregates EN 1

20、t 05 02:52:09 GMT+00:00 2007, Uncontrolled Copy, (c) BSI EN 1744-6:2006 (E) 4 1 Scope This European Standard specifies the procedure for the determination of the influence of water- soluble components from recycled aggregates on the initial setting time of cement. NOTE A procedure is described in EN
21、 1744-1:1998, clause 15.3, for use with natural aggregates; this procedure is intended to demonstrate and quantify the effects of organic contaminators. It is not suitable for recycled aggregates because these may also contain inorganic contaminators. 2 Normative references The following referenced

For undated references, the latest edition of the referenced document (including any amendments) applies. EN 196-3, Methods of testing cement Part 3: Determination of sett
