BS EN 12808-4:2009EN 12808-4:2009 (E) 4 1 Scope This European Standard applies to all ceramic tile grouts for internal and external tile installations on walls and floors. This European Standard specifies the test
20、 method to be used to determine the shrinkage of ceramic tile grouts. This European Standard does not contain performance requirements or recommendations for the design and installation of ceramic tiles. NOTE Ceramic tile grouts can also be used for other types of tiles (natural and agglomerated sto
21、nes, etc.), where these do not adversely affect the stones. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (i
22、ncluding any amendments) applies. EN 196-1, Methods of testing cement Part 1: Determination of strength EN 1067, Adhesives Examination and preparation of samples for testing EN ISO 15605, Adhesives Sampling (ISO 15605:2000) 3 Sampling Take a sample of at least 2 kg of the product to be tested in acc
23、ordance with EN ISO 15605 and EN 1067. 4 Test conditions Standard conditions shall be (23 2) C and (50 5) % R.H. and a speed of air in the working area less than 0,2 m/s. 5 Test materials Condition all test materials for at least 24 h under standard conditions. 6 Apparatus 6.1 Moulds, used to prepar
24、e prismatic specimens 10 mm 40 mm 160 mm (three-gang mould), with ground surfaces, made of steel, in accordance with EN 196-1. Holes for fitting suitable pins shall be drilled into the ends of the sides of the moulds corresponding to the ends of test specimen (see Figure 1): a) moulds with horizonta
25、l compartments 10 mm 40 mm 160 mm, or b) moulds with horizontal compartments 40 mm 40 mm 160 mm and width reducing plastic or metal inserts (6.2), two for each mould. BS EN 12808-4:2009EN 12808-4:2009 (E) 5 6.2 Six smooth, rigid, non-absorbent frames (e.g. in polyethylene or PTFE) to be inserted, wi
26、th dimensions of 40 mm x 160 mm and thickness of 15 mm. 6.3 Jolting apparatus or jolting table used for the compaction of 10 mm x 40 mm x 160 mm grout specimen; in accordance with EN 196-1. 6.4 Measuring apparatus that shall consist of a measurement attachment and a base with adjustment screws. The
27、measurement attachment shall be formed either by an analogue or digital gauge, which reads accurately to 0,01 mm, rigidly mounted in a measuring frame (see Figures 2, 3 and 4). 6.5 Calibration rod or reference rod that shall be used as a standard length against which gauge readings can be tested. Th
28、e rod shall be made of material having a negligible coefficient of expansion (e.g. Invar). 7 Procedure 7.1 Mixing of grouts The amount of water and/or liquid admix required for preparing the cementitious grout shall be as stated by the manufacturer in parts by mass, i.e. liquid to dry powder. Prepar
29、e at least 2 kg of the grout in a mixer of the type described in EN 196-1, using the slow speed settings, (140 5) r/min rotation and (62 5) r/min planetary movement. Carry out the following procedure: pour the liquid into the pan; scatter the dry powder over the liquid; mix for 30 s; take out the mi
30、xing paddle; scrape down the paddle and pan within 1 min; replace the paddle and mix for 1 min. Let the grout mature if and as specified in the manufacturers instructions, and then mix for a further 15 s. In the case of reaction resin grouts follow the manufacturers instructions. 7.2 Preparation of
31、test specimens Insert two non-absorbent frames at the sides of each compartment of the mould, to reduce the width to 10 mm. Apply a thin layer of release agent to the internal faces of the mould. Mould the specimens immediately after the preparation of the grout, with the mould firmly clamped to the
32、 jolting table. Introduce, using a suitable scoop, the first of two layers of grout into each of the compartments, directly from the mixing bowl. Spread the layer uniformly, then compact using 60 jolts. Introduce the second layer of grout, level and compact with a further 60 jolts. BS EN 12808-4:200
33、9EN 12808-4:2009 (E) 6 Lift the mould gently from the jolting table, strike off excess of material and smooth the surface with a flat trowel. Wipe off the grout left on the perimeter of the mould. Cover with a glass plate according to EN 196-1. Place the mould, suitably identified, on a horizontal b
34、ase in standard conditions, (23 2) C and (50 5) % R.H. After 24 h remove carefully the specimen from the mould and determine with the measuring apparatus (6.4) the length of the test sample (initial reading). Keep the demoulded prism in standard conditions leaving a clearance of at least 25 mm on al
35、l sides. Prepare three specimens for each grout. 7.3 Test procedure Take the reading of each specimen 27 days 12 h after the initial reading. 8 Evaluation of results The linear shrinkage is evaluated in mm/m as the mean of three values based on the initial measurement. 9 Test report The test report
36、shall provide the following information: c) number, title and issue of this European Standard; d) place and date of sampling; e) type of grout, commercial designation and manufacturer name; f) identification of the test sample; g) handling and storage of samples before testing; h) test conditions; i
37、) date of testing; j) amount of water or liquid used for preparing the grout; k) test results (individual and means values) in mm/m; l) any other factor that could have influenced the result.
