12、 2004 (E) 3 Foreword This document (EN 14497:2004) has been prepared by Technical Committee CEN/TC 104 “Concrete and related products”, the secretariat of which is held by DIN. It has been drafted by Sub-Committee 8 “Products and systems for the protection and repair of concrete structures“ (Secreta

13、riat AFNOR). 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of an identical text or by endorsement, at the latest by March 2005, and conflicting national standards shall be withdrawn at the latest by March 2005. According to the CEN/CENELEC Internal Re

14、gulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands,

EN 14497:2004 (E) 4 1 Scope This document describes a test method to determine the filtration stability of cementitious injection products. This test can also be used: to check the filtration stability and

16、workable time in situ with the used mixing equipment, mixing time and temperature. for assessment of mixing stability and required mixing time, with the mixing equipment used. 2 Normative references The following referenced documents are indispensable for the application of this document.

20、th and to enter cracks without agglomeration Test principle The cementitious injection product is drawn into a filtration device by suction and then pressed out into a measuring vessel. The amount that has passed the filter is measured and registered as a measure of filtration stability. The filter

21、consists of a woven metal wire cloth. The cloth shall have a mesh width of 32 m, 45 m, 75 m, 100 m or 125 m, depending on the expected performance of the product to be tested. 4 Significance and use The most significant limitation to the penetrability of a cementitious injection product in a fine cr

22、ack is the tendency of cement grains to agglomerate into an impermeable filter cake. Clogging of the crack can occur by a combination of several factors including: large cement grains too large for the crack; poor initial dispersion of the cement grains; EN 14497: 2004 (E) 5 agglomeration when the g

23、rout is exposed to filtration situations such as entrances to fine cracks or porous material. This test can also be used: for assessment of mixing ability and required mixing time, with the mixing equipment used; for determination of pot life; to check the filtration stability and workable time in s

24、itu with the used mixing equipment, mixing time and temperature. 5 Apparatus 5.1 Suction filtration device, according to Figure 1. The body shall be made of non-corroding metal. 5.2 Woven metal wire cloths with mesh apertures of 125 m, 100 m, 75 m, 45 m and 32 m according to ISO 565. 5.3 Graduated b

25、eaker with an internal diameter of (105 5) mm and a height of at least 140 mm. 5.4 Measuring cylinder, with a capacity of 500 ml. 5.5 Stop-watch with an accuracy of 1 s. 5.6 Cementitious injection product mixer. 5.7 Thermometer with an accuracy of 0,5 C. 6 Sampling and preparation The temperature of

26、 the dry materials and mixing water shall be (21 2) C; the mixing procedure shall be in accordance with the manufacturers instructions; if it is required to test the mixture after a longer holding period, continue mixing of the remaining portion at slow speed for the specified time, If necessary (gi

27、ven by the manufacturers instruction). 7 Procedure The standard conditions of test shall be (21 2) C and (60 10) % ; The woven metal wire cloth in question (125 m, 100 m ,75 m, 45 m or 32 m) is fixed to the filtration suction device; The determination shall be made in duplicate. EN 14497:2004 (E) 6

28、the product is poured into a graduated beaker to the 1,0 l graduation mark within (5 1) min of the completion of mixing, unless otherwise stated. The suction filtration device is immersed in the grout in such a way that the bottom of the suction device is situated at half the height of the injection

29、 product fiilling level (see Figure 2). The handle of the suction device is immediately drawn up. This shall be done with a constant speed and the whole procedure shall take (5 2) s. The suction device is kept immersed in the same position for (20 5) s further. Then the suction device is taken up fr

30、om the graduated beaker and the content of the suction device pumped into the measuring vessel. The suction filtration device is cleaned by suction and pumping water through the device several times directly after the test. The remaining part in the vessel, which has earlier been tested, is not allo

31、wed to be tested again;the volumes passing through the mesh into the device are measured in ml with an accuracy of 5ml. the procedure starts with the 125 m metal wire cloth and if the suction device is completely filled (300 ml) the procedure is repeated for the following wire cloth and so forth, un

32、til the volume passing through the sieve is less than 20 ml; the repetition shall be made within 3 min. If one particular mesh size is expected to be suitable, the remaining wire cloths may be omitted. If the test is carried out with different mesh sizes it is advisable to have one device for each s

33、ize of mesh. 8 Expression of results The volumes passing through the mesh into the device are measured in ml with an accuracy of 5 ml. The determination shall be made in duplicate, for each selected mesh/size. 9 Report The test report shall contain the following informations: a) reference to the tes

34、t method standard; b) name and address of the test laboratory; c) identification number and date of the test report; d) name and address of the manufacturer or supplier of the product; e) name and identification marks or batch number of the product; f) date of supply of the product; g) procedure of

35、mixing the product (water content, description of mixing equipment, duration of mixing); h) time from the completion of the mixing until the test was made; i) date of test and details of the test equipment used, including the make, type and capacity and the calibrations details or the identification

36、 number of the apparatus; j) test results: individual and average values measured for each selected metal wire cloth; k) accuracy data; l) date of test report and signature.
