16、R. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2002, and conflicting national standards shall be withdrawn at the latest by December 2002. This European Standard is one of a series de

17、aling with products and systems for the protection and repair of concrete structures. It describes a method for determining the workability of free-flowing repair concrete mixes. It is one of a series of inter-related parts dealing with the workability of repair grouts, mortars and concretes. The ot

18、her parts are: EN 13395-1, Products and systems for the protection and repair of concrete structures Test methods Determination of workability Part 1: Test for flow of thixotropic mortars ; EN 13395-2, Products and systems for the protection and repair of concrete structures Test methods Determinati

According to the CEN/CENELEC Internal Regulations, the national

20、standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

21、EN 13395-3:2002 (E) 4 1 Scope This European Standard specifies a method for determining the workability of high flow hydraulic cement, PCC and PC based concrete products for the protection and repair of concrete, as defined in EN 1504-3, whose workability is outside the normal range for concrete as

22、defined in ENV 206. Tests for the workability of repair products and systems based on thixotropic mortar and high flow grout or mortar are contained in prEN 13395-1 and prEN 133952 respectively. Normal workability concrete mixes, which can include proprietary formulations, are applied and compacted

23、in accordance with conventional practice. The workability of these products should be assessed using the slump, VeBe or other appropriate method given in EN 206-1. The workability of conventional high flow concrete mixes should be assessed by the method of EN 12350-5. 2 Normative references This Eur

24、opean Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publicatio

25、ns apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).

28、1504-1 and the following apply. 3.1 flow time the time taken for a fixed volume of concrete to flow 750 mm along a trough 4 Principle The principle of this test is to provide a relevant method to evaluate the workability of high flow repair concrete in the laboratory, which reflects the actual worka

29、bility requirements for site concrete repair works. The test measures the time taken for a fixed volume of the concrete to flow 750 mm along a defined horizontal trough. NOTE 1 High flow repair concretes are specially formulated mixes with a maximum aggregate size of 10 mm that are unsuitable for te

30、sting by normal workability tests (i.e. EN 206-1 or EN 12358). NOTE 2 The method of test is sufficiently robust as to be suitable for use as a quality control technique in site laboratories.1Under preparation.EN 13395-3:2002 (E) 5 5 Equipment 5.1 Concrete mixer as specified in EN 206-1. 5.2 Flow tro

32、ing materials, including the mix water and the test equipment (5.2 and 5.3) shall be conditioned in either the standard laboratory climate (5.4) or the climatic chamber (5.5) for a period of not less than 24 h prior to mixing. Assemble the funnel support and funnel and locate onto the trough, ensuri

33、ng that the edge of the funnel support is aligned with the edge of the trough. Ensure that the test equipment is rigidly supported such that the trough is horizontal and free from vibration. Unless otherwise instructed by the manufacturer, mix the concrete in accordance with EN 206-1 at the required

34、 temperature. Carry out the testing of the concrete immediately after completion of mixing and then again (30 1) min after mixing. Gently re-agitate the concrete every five minutes between the two tests. Immediately before carrying out the test, flood the surfaces of the funnel and trough with water

35、 and drain-off excess water by inverting the test equipment for one minute. Fit the bung and charge the funnel with six litres of concrete. Pull the bung upwards to release the concrete and record the time taken for the concrete to flow a distance of 750 mm along the trough (the “flow time”) and the

36、 maximum distance flowed. Record any evidence of bleeding or segregation that occurs in the concrete. Carry out three repeat tests at both temperatures (5.4 and 5.5) and at both times after mixing, resulting in a total of twelve tests. 7 Test report a) a reference to the test method standard; b) nam
