This European Standard is
17、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

22、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 incorporates by dated or undated reference, provisions from other publications.

26、rovide 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 test measures the flow of a fixed quantity of the grout or mortar along a defined trough after 30 s. The distance
27、that the grout or mortar has travelled in that time is the flow value. NOTE laboratories. The method of test is sufficiently robust as to be suitable for use as a quality control technique in on-site 5 Equipment 5.1 for the grout shall be the standard type of mixer specified for producing cement mor

29、trough. 5.4 Standard laboratory climate of (21 f 2) OC and (60 f IO) % RH. 4 EN 1 3395-212002 (E) 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 c
30、arried out in accordance with the manufacturers instructions. The grout flow trough shall be 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
31、The flow of the grout shall be determined at the standard laboratory temperature (5.4) 5 min, 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. NOTE In addition, the flow value for the mortar may be determined at other te
32、mperatures for special applications. The surfaces of the grout flow trough shall be moistened 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 su
33、rface should be gently rodded to level the surface if required. The pull-rod shall be pulled 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 o
34、f the discharge outlet to the end of the grout after a period of 30 s (the “flow value”). If 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 reference to the test method standard; name and addr
35、ess of the test laboratory; identification number and date of the test; name and address of the manufacturer or supplier of the product; name and identification marks or batch number of the product, including the maximum aggregate size; date of supply of the product; date of preparation of the test
36、specimens and any deviation from the prescribed method of preparation; 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; date of test and details of the test equipment used, incl
