30、ng to EN 1542. 5.7 Pull-off equipment for measuring the pull-off strength, according to EN 1542. 6 Test procedure Two concrete slabs (see 5.2), conditioned in accordance with the manufacturers instructions, are mounted with the grit blasted surfaces at the bottom. NOTE 1 repair mortar or concrete. T
31、he substrates can be supported by form work on two sides (see 5.4) to ensure the required uniform thickness of The layer thickness shall be (20 f 2) mm for repair mortars up to 5 mm maximum particle size and (40 f 4) mm for repair materials with larger maximum particle sizes, unless recommended othe
32、rwise by the manufacturer. All materials shall be conditioned in the standard laboratory climate (5.1) for a period of not less than 24 hours prior to mixing. The repair mortar or concrete is mixed according to the manufacturers instructions. If no particular instructions are given, the maximum wate
33、r content should be applied in the case of CC and PCC. The repair mortar or concrete is applied to the overhead surface of the prepared substrates according to the manufacturers instructions. NOTE 2 If required, the substrates may be pre-wetted and/or a bonding aid used. After application to the req
34、uired layer thickness, the surface shall be finished with a steel float (5.5) to provide a smooth surface. The test specimens shall then be cured and stored according to annex A. After the cure periods (28 days for CC and PCC, 7 days for PC repair mortars - see annex A) the pull off strength shall b
