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of an identical text or by endorsement, at the latest by November 2002, and conflicting national standards shall be withdrawn at the latest by December 2002.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
18、one of a series dealing with products and systems for the protection and repair of concrete structures. It describes a method for determining the flow characteristics of repair grouts and mortars. It is one of a series of inter-related parts dealing with the workability of repair grouts, mortars and
19、 concretes.

23、ortars CC, polymer modified hydraulic cement mortars PCC and polymer bound mortars PC for the protection and repair of concrete, as defined in EN 1504-1. The method is suitable for high flow grouts or mortars that have a maximum aggregate size of 4 mm. 2 Normative references This European Standard i

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 publications apply to this
25、 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).

26、on and repair of concrete structures - Definitions, requirements, quality control and evaluation of conformity - Part 1: Definitions. 3 Terms and definitions For the purposes of this European Standard, the terms and definitions contained in EN 1504-1 and the following apply. 3.1 flow value distance
27、that the grout or mortar has travelled along a trough after 30 s 4 Principle The principle of this test is to provide a relevant method to evaluate the workability of flowing repair grouts or mortars in the laboratory, which reflects the actual workability requirements for site repair works. The tes
28、t measures the flow of a fixed quantity of the grout or mortar along a defined trough after 30 s. The distance that the grout or mortar has travelled in that time is the flow value. NOTEThe method of test is sufficiently robust as to be suitable for use as a quality control technique in on-site labo
29、ratories. 5 Equipment 5.1Mixer : Unless stated otherwise by the manufacturer, the equipment to be used for mixing the constituents for the grout shall be the standard type of mixer specified for producing cement mortars in EN 196-1. 5.2Grout flow trough : A grout flow trough fabricated in accordance
30、 with Figure 1. 5.3Measuring jug : Capable of taking the required one litre of grout used in the grout flow trough. 5.4Standard laboratory climate of (21 2) ?C and (60 10) % RH.

31、 (E) 5 6 Preparation All materials shall be conditioned in the standard laboratory climate (5.4) for a period of not less than 24 h prior to mixing. The proportioning and mixing of the repair grout shall be carried out in accordance with the manufacturers instructions. The grout flow trough shall be
32、 brought into the climatic chamber for a period of 24 h prior to use. The grout flow trough shall be positioned in its final testing position by adjusting the screws until the base is level. 7 Test Procedure The flow of the grout shall be determined at the standard laboratory temperature (5.4) 5 min
33、, 15 min, 30 min and 60 min after mixing. The mixed mortar shall be agitated in the grout mixer for five seconds prior to testing. NOTEIn addition, the flow value for the mortar may be determined at other temperatures for special applications. The surfaces of the grout flow trough shall be moistened
34、 with a damp cloth within one minute of carrying out the test. A one litre sample of grout shall be poured into the charging hopper of the grout flow trough, ensuring the surface of the grout is even; the surface should be gently rodded to level the surface if required. The pull-rod shall be pulled
35、upwards gently in a smooth operation after 30 s of charging the hopper, allowing the grout to flow evenly down the trough. The flow of the grout shall be measured as the horizontal distance from the centre of the discharge outlet to the end of the grout after a period of 30 s (the “flow value”). If
36、the grout is still moving along the grout flow trough, this fact should be noted. 8 Test report The test report shall include the following information: a) a reference to the test method standard; b) name and address of the test laboratory; c) identification number and date of the test; d) name and
37、address of the manufacturer or supplier of the product; e) name and identification marks or batch number of the product, including the maximum aggregate size; f) date of supply of the product; g) date of preparation of the test specimens and any deviation from the prescribed method of preparation; h
38、) conditions of storage of prepared specimens prior to test, including the period of delay between completion of mixing and testing and evidence of segregation and bleeding; i) date of test and details of the test equipment used, including the make, type and capacity and the calibration details or t
39、he identification number of the apparatus; j) the test results, including the distance of flow of the grout after 30 s (the “flow value”) and whether the grout is still moving; k) precision data; Licensed Copy: sheffieldun sheffieldun, na, Mon Oct 30 06:18:18 GMT+00:00 2006, Uncontrolled Copy, (c) B
