19、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 method to be used to determine the water absorption coefficient due to capillary action when the grout surface contacts the wa
20、ter without any additional pressure. The coefficient is measured by means of prisms. This European Standard does not contain performance requirements or recommendations for the design and installation of ceramic tiles. NOTE Ceramic tile grouts may also be used for other types of tiles (natural and a
21、gglomerated stones, 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 referen
22、ced document (including any amendments) applies. EN 196-1:2005, Method 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 produc
23、t to be tested in accordance 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 T
24、hree gang mould with ground surfaces, made of steel, used for the preparation of 40 mm x 40 mm x 160 mm prisms, in accordance with Clause 4.5 of EN 196-1:2005. 6.2 Jolting apparatus or jolting table used for the compaction of 40 mm x 40 mm x 160 mm grout specimen, in accordance with Clause 4.6 of EN
25、 196-1:2005. 6.3 Tray with a flat base, large enough to contain three test specimens. BS EN 12808-5:2008EN 12808-5:2008 (E) 5 7 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 weight, i.e. liqui
26、d to dry powder. Prepare at least 2 kg of the grout in a mixer of the type described in Clause 4.4 of EN 196-1:2005, 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
27、 the liquid; mix for 30 s; take out the mixing 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 manuf
28、acturers instructions. 8 Preparation of test specimens Insert a 1 mm thick, rigid, plastic (e.g. PTFE) or metal divider into each compartment of the mould, approximately in the middle, parallel to the ends. Mould the specimens immediately after the preparation of the grout, with the mould firmly cla
29、mped to the 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. Lift t
30、he 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 the mould with a glass plate according to EN 196-1. Place the mould, suitably identified, on a horizontal base in standard con
31、ditions, (23 2) C and (50 5) % R.H. After 24 h carefully remove the specimen from the mould. Keep the demoulded prisms for 27 days in standard conditions leaving a clearance of at least 25 mm on all sides. Prepare six specimens for each grout. BS EN 12808-5:2008EN 12808-5:2008 (E) 6 9 Conditioning T
32、he test units are conditioned for 27 days in standard conditions, (23 2) C and (50 5) % R.H. 10 Test procedure After 21 days from manufacture seal the side faces by means of a neutral curing silicone sealant so as to be water impermeable. After 28 days from manufacture, weigh, with 0,1 g precision,
33、each test sample and then place them in the tray, with the upper surface down, immersed in water, 5 mm to 10 mm deep, taking care to prevent the prism faces from coming in contact with each other. Maintain the water level constant by adding water when necessary. After 30 min remove the test samples
34、from water, quickly dry them by blotting with a dampened cloth and immediately weigh. Replace in the tray and repeat the procedure after 210 min. 11 Evaluation and expression of results Calculate the water absorption, in grams, after 30 min and 240 min of each sample using the following formula: dtm
35、m =mtW where: Wmt is the water absorption, in grams; md is the mass of the dry specimen, in grams; mtis the mass of the specimen after immersion, in grams. Calculate the mean of at least three test samples. 12 Test report The test report shall provide the following information: a) number, title and
36、issue of this European Standard; b) place and date of sampling; c) type of grout, commercial designation and manufacturer name; d) identification of the test sample; e) handling and storage of samples before testing; f) test conditions; g) date of testing; h) amount of water or liquid used for prepa
37、ring the grout; i) test results (water absorption, individual and mean values after 30 min and 240 min); j) any other factor that could have influenced the result.
